The edge touch screen 190 may include the main display area 190a and the edge display areas 190b and 190c. The main display area 190a may be flat or have a curvature (for example, approximate to a flat surface) smaller than curvatures of the edge display areas 190b and 190c.

According to an embodiment of the present disclosure, the main touch screen may include a touch screen corresponding to the main display area 190a. Further, the edge touch screen may include a touch screen corresponding to the edge display areas 190b and 190c. The main touch screen area may include a touch screen area corresponding to the main display area 190a. Further, the edge touch screen area may include a touch screen area corresponding to the edge display areas 190b and 190c.

The first edge touch screen may refer to a touch screen corresponding to one edge display area between the edge display areas 190b and 190c. The second edge touch screen may refer to a touch screen corresponding to the other edge display area, which is not the first edge touch screen area, between the edge display areas 190b and 190c. For example, when the first edge touch screen is the touch screen corresponding to the edge display area 190b, the second edge touch screen may be the touch screen corresponding to the edge display area 190c. In contrast, when the first edge touch screen is the touch screen corresponding to the edge display area 190c, the second edge touch screen may be the touch screen corresponding to the edge display area 190b.

The main display area 190a may be separated from the edge display areas 190b and 190c by virtual lines 190b1 and 190c1. The virtual lines 190b1 and 190c1 may refer to lines from which the curvature of the main display area 190a starts being changed. The virtual lines 190b1 and 190c1 may also refer to lines at which the curvature of the main display area 190a is changed to the curvature of the edge display areas 190b and 190c. The virtual lines 190b1 and 190c1 may correspond to lines at which the curvature of the main display area 190a is changed to one of first curvatures of the single curvature and the multi-curvature of the edge display areas 190b and 190c.

In the edge display areas 190b and 190c, the single curvature may refer to the edge display areas 190b and 190c having one curvature. For example, the single curvature is larger than or equal to 13 R and equal to or smaller than 5 R. Cross sections (not shown) of both sides of the portable device including the edge display areas 190b and 190c having the single curvature may include a semicircle or an oval.

In the edge display areas 190b and 190c, the multi-curvature may refer to the edge display areas 190b and 190c having a first curvature corresponding to areas including the virtual lines (including 190b1 and 190c1), which are extended and bended from the main display area 190a, and a second or more curvature corresponding to areas (for example, including edge areas 190b2 and 190c2 of the edge display areas 190b and 190c) contacted with the bezel of the front surface, the second curvature being different from the first curvature.

For example, the first curvature may be 12 R or 13 R, where R is the radius of a curvature between a front surface and a rear surface of the portable device 100. The first curvature may be larger than or equal to 13 R and equal to or smaller than 5 R. Further, the second curvature may be 6.5 R or 6.9 R. The second curvature may be larger than or equal to 8 R and equal to or smaller than 4 R. Cross sections (not shown) of both sides of the portable device including the edge display areas 190b and 190c having the multi-curvature may include a semicircle or an oval.

The curvature of the left edge display area 190b and the curvature of the right edge display area 190c may be different. When the edge display areas 190b and 190c correspond to the single curvature, the curvature of the left edge display area 190b may be, for example, 13 R. Further, the curvature of the right edge display area 190c may be 6.5 R.

One of the edge display areas 190b and 190c may have the single curvature, and the other edge display area may have the multi-curvature. For example, the left edge display area 190b may correspond to the single curvature and the right edge display area 190c may correspond to the multi-curvature. The single curvature of the left edge display area 190b may be 13 R, and the first curvature of the right edge display area 190c may be 12 R and the second curvature of the right edge display area 190c may be 6.5 R.

In an embodiment of the present disclosure, the single curvature value and/or the multi-curvature value are only examples and the present disclosure is not limited thereto. It is easily understood by those skilled in the art that the single curvature value and/or the multi-curvature value can be changed.

The successive motions of the second touch 511 may be stored in the storage unit 175 under a control of the controller 110. The number of touches contacted on the second edge touch screen 190c may be singular or plural.

The successive motions (for example, a movement from a first location 511a to a second location 511b, from the second location 511b to a third location 511c, and from the third location 511c to a last location 511d) of the second touch 511 may refer to a second touch gesture detected on the second edge touch screen 190c. The successive motions (for example, the movement from the first location 511a to the last location 511d) of the second touch 511 may refer to the second touch gesture detected on the second edge touch screen 190c in a down direction (for example, y axis direction).

The successive motions (for example, the movement from the first location 511a to the last location 511d) of the second touch 511 may mean that the contact between the second edge touch screen 190c and the second touch 511 is continuously maintained. Further, in the successive motions of the second touch 511, the contact on the second edge touch screen 190c may be touch-released at the last location 511d.

The successive motions (for example, a movement from the first location 511a to the last location 511d) of the second touch 511 may refer to the second touch gesture detected from the second edge touch screen 190c to the main touch screen 190a. The successive motions (for example, the movement from the first location 511a to the last location 511d) of the second touch 511 may mean that the contact of the second touch 510 from the second edge touch screen 190c to the main touch screen 190a is continuously maintained. Further, in the successive motions of the second touch 511, the contact on the main touch screen 190a may be touch-released at the last location 511d.

In an embodiment of the present disclosure, there may be a plurality of touches included in the “successive motions of the touch”, however the above described four touch locations are only an embodiment and the present disclosure is not limited thereto. It is easily understood by those skilled in the art that the number of touches included in the successive motions of the touch can be changed.

Referring to FIG. 5C, the successive motions of the second touch 511 in a down direction from the second edge touch screen 190c may include a drag, drag & drop, flick, or swipe. Further, the successive motions of the second touch 511 in a down direction from the second edge touch screen 190c to the main touch screen 190a may include a drag, drag & drop, flick, or swipe.

In operation S406 of FIG. 4A, successive motions of the first and/or second touch moving in a down direction are detected.

Referring to FIG. 5C, the first touch 510 successively moving in a down direction (for example, y axis direction) may arrive at the last location 510d from the first location 510a. The controller 110 may calculate the last location 510d of the first touch 510 moving in the down direction on the first edge touch screen 190b by using the edge touch screen controller 195 and the storage unit.

The last location of the first touch 510 successively moving in the down direction may be different according to a route and/or a movement distance of the successive motions of the first touch 510. For example, the last location of the first touch 510 successively moving in the down direction may be one of 510b, 510c, and 510d included along the route of the successive motions of the first touch 510. Further, when the movement distance of the successive motions of the first touch 510 is short, the last location of the first touch 510 successively moving in the down direction may be the location 510b. When the movement distance of the successive motions of the first touch 510 is long, the last location of the first touch 510 successively moving in the down direction may be the location 510d or 510c.

The controller 110 may detect the successive motions of the first touch 510 in the down direction by using an allowable slope range (not shown). The controller 110 may calculate a slope of a straight line connecting the first location 510a and the last location 510b, 510c, or 510d, of the first touch 510.

When a horizontal direction and a vertical direction of the portable device 100 correspond to an x axis direction and a y axis direction, respectively, the allowable slope range of the successive motions of the first touch 510 in the down direction may refer to an area between an extension line from the first location 510a corresponding to a slope of +45 degrees in a +x axis direction based on the y axis, and an extension line corresponding to a slope of −45 degrees in an x axis direction. A slope of −45 degrees in a −x axis direction may be limited by the edge area 190b2. The allowable slope range may be equal to or smaller than ±5 degrees, equal to or smaller than ±15 degrees, equal to or smaller than ±25 degrees, equal to or smaller than ±35 degrees, or equal to or smaller than ±65 degrees, but embodiments are not limited thereto.

The storage unit 175 may store allowable slope information corresponding to the allowable slope range under a control of the controller 110.

It is easily understood by those skilled in the art that the allowable slope range can be changed in accordance with the horizontal length and/or the vertical length of the first edge touch screen 190b. Further, it is easily understood by those skilled in the art that the allowable slope range can be changed in accordance with the horizontal length of the first edge touch screen 190b and the main touch screen 190a and/or the vertical length of the first edge touch screen 190b and the main touch screen 190a.

In an embodiment of the present disclosure, the last location of the first touch 510 successively moving in the down direction may be in an area within the allowable slope range.

The controller 110 may detect the successive motions of the first touch 510 in the down direction by using a setting area (not shown). The setting area may refer to a semicircle with a radius of 3 cm having the first location 510a of the first touch 510 as the center in a y axis direction. The semicircle with the radius of 3 cm in a −x axis direction may be limited by the edge area 190b2. The radius of the setting area may be equal to or smaller than 1 cm, equal to or smaller than 2 cm, equal to or smaller than 3 cm, equal to or smaller than 4 cm, or equal to or smaller than 5 cm, but embodiments are not limited thereto.

The storage unit 175 may store setting area information corresponding to the setting area under a control of the controller 110.

It is easily understood by those skilled in the art that the setting area can be changed in accordance with the horizontal length (for example, y axis direction) and/or the vertical direction (for example, x axis direction) of the first edge touch screen 190b. Further, it is easily understood by those skilled in the art that the setting area can be changed in accordance with the horizontal length of the first edge touch screen 190b and the main touch screen 190a and/or the vertical length of the first edge touch screen 190b and the main touch screen 190a.

In an embodiment of the present disclosure, the last location of the first touch 510 successively moving in the down direction may be within the setting area. The route from the first location 510a to the last location of the first touch 510 successively moving in the down direction may pass through the setting area.

The controller 110 may detect the successive motions of the first touch 510 in the down direction based on a combination of an time interval as well as the allowable slope range and the setting area. For example, the controller 110 may detect the successive motions of the first touch 510 in the down direction by using a combination of the allowable slope range and the time interval and a combination of the setting area and the time interval.

The time interval may refer to an interval between the time of the first location 510a of the first touch 510 and the time of the last location 510d. For example, the time interval may be equal to or smaller than 500 ms. The time interval may be equal to or smaller than 100 ms, equal to or smaller than 200 ms, equal to or smaller than 300 ms, equal to or smaller than 500 ms, equal to or smaller than 700 ms, or equal to or smaller than 1000 ms, but embodiments are not limited thereto.

The storage unit 175 may store time interval information corresponding to the combination of the allowable slope range and the time interval, and the combination of the setting area and the time interval, under a control of the controller 110.

In an embodiment of the present disclosure, the last location of the first touch 510 successively moving in the down direction may be in an area within the allowable slope range within the time interval.

In an embodiment of the present disclosure, the last location of the first touch 510 successively moving in the down direction may be within the setting area within the time interval. Further, the route from the first location 510a to the last location of the first touch 510 successively moving in the down direction may pass through the setting area within the time interval.

Referring to FIG. 5C, the second touch 511 successively moving in the down direction (for example, y axis direction) may arrive at the last location 511d from the first location 511a. The controller 110 may calculate the last location 511d of the second touch 511 moving in the down direction on the second edge touch screen 190c by using the edge touch screen controller 195 and the storage unit 175.

The last location of the second touch 511 successively moving in the down direction may be different according to a route and/or a movement distance of the successive motions of the second touch 511. For example, the last location of the second touch 511 successively moving in the down direction may be one of 511b, 511c, and 511d, included along the route of the successive motions of the second touch 511. Further, when the movement distance of the successive motions of the second touch 511 is short, the last location of the second touch 511 successively moving in the down direction may be the location 511b. When the movement distance of the successive motions of the second touch 511 is long, the last location of the second touch 511 successively moving in the down direction may be the location 511d or 511c.

The controller 110 may detect the successive motions of the second touch 511 in the down direction by using an allowable slope range. The controller 110 may calculate a slope of a straight line connecting the first location 511a and the last location 511b, 511c, or 511d of the second touch 511.

Since the detection of the successive motions of the second touch 511 in the down direction using the allowable slope range in operation S406 of FIG. 4A is substantially similar (for example, a touch difference) to the detection of the successive motions of the first touch 510 in the down direction using the allowable slope range, a duplicate description will be omitted.

For example, the time interval may be equal to or smaller than 500 ms. The time interval may be equal to or smaller than 200 ms, equal to or smaller than 300 ms, equal to or smaller than 500 ms, equal to or smaller than 700 ms, or equal to or smaller than 1000 ms, but embodiments are not limited thereto.

In an embodiment of the present disclosure, the last location of the second touch 511 successively moving in the down direction may be within the setting area within the time interval. Further, the route from the first location 511a to the last location of the second touch 511 successively moving in the down direction may pass through the setting area within the time interval.

Referring to FIG. 5G, the controller 110 may display a thumbnail image 504 in response to the first touch 510 (for example, a movement from the location 510a to a location 510e) successively moving in the down direction and/or the second touch 511 (for example, a movement from the location 511a to a location 511e) successively moving in the down direction. Further, the controller 110 may display another screen (including another screen including the thumbnail image 504) (not shown) except for the first screen 500, the second screen 520 (see FIG. 5D), and the third screen 530 (see FIG. 5F) in response to the first touch 510 (for example, the movement from the location 510a to the location 510e) successively moving in the down direction and/or the second touch 511 (for example, the movement from the location 511a to the location 511e) successively moving in the down direction.

The controller 110 may display one or a plurality of thumbnail images in response to the first touch 510 successively moving in the down direction and/or the second touch 511 successively moving in the down direction. When a plurality of thumbnail images are displayed in response to the first touch 510 successively moving in the down direction and/or the second touch 511 successively moving in the down direction, the controller 110 may display each of the thumbnail images at a regular time interval (for example, 50 ms, but values can be changed).

The controller 110 may display the thumbnail image 504 only in the main touch screen area. Further, the controller 110 may display the thumbnail image 504 over the main touch screen area and the edge touch screen area as illustrated in FIG. 5G.

The controller 110 may also display the thumbnail image 504 before the touch arrives at the last location of the first touch 510 and/or the touch arrives at the last location of the second touch 511.

The controller 110 may provide feedback corresponding to the arrival at the last location of the first touch 510 to the user. The controller 110 may also provide feedback corresponding to the arrival at the last location of the second touch 511 to the user. Further, the controller 110 may provide feedback corresponding to the arrival at the last location of the first touch 510 and the arrival at the last location of the second touch 511 to the user.

The provided feedback may be provided as one of a visual feedback, an audible feedback, and a tactile feedback. Further, the controller 110 may provide a combination of the visual feedback, the audible feedback, and the tactile feedback to the user.

Further, the audible feedback may include a sound corresponding to the arrival of the last location of the second touch 510 and the arrival of the last location of the second touch 511.

The controller 110 may output the audible feedback through the speaker 163. For example, the controller 110 may output the audible feedback through one of the first speaker 163a and the second speaker 163b. Further, the controller 110 may output the audible feedback through a combination of the speaker 163a and the speaker 163b.

A feedback provision time (for example, 500 ms) provided to the user may be changed through environment settings (not shown). Further, at least one of a plurality of feedbacks (for example, the visual feedback, the audible feedback, and the tactile feedback) provided in response to the arrival at the lost location of the first touch 510 and/or the second touch 511 may be selected.

When the successive motions of the first and second touches successively moving in the down direction are not detected, operation S408 is performed.

When the successive motions of the first and second touches successively moving in the down direction are detected, a first screen is changed to another screen corresponding to a first order among a plurality of screens in operation S407.

Referring to FIG. 5D, the controller 110 may change the first screen 500 to another screen 520 (for example, a first screen among the plurality of screens) corresponding to the first order among the plurality of screens in response to the arrival at the last location of the first touch 510.

When the first touch 510 successively moves in the down direction, but and the second touch 511 does not move, the controller 110 may change the first screen 500 to another screen 520 (for example, an initial screen among the plurality of screens) corresponding to the first order among the plurality of screens in response to the arrival at the last location of the first touch 510. When the second touch 511 successively moves in the down direction, but the first touch 510 does not move, the controller 110 may change the first screen 500 to another screen 520 (for example, a first screen among the plurality of screens) corresponding to the first order among the plurality of screens in response to the arrival at the last location of the second touch 511.

The other screen 520 may be a first screen corresponding to a first order of the first screen 500 (for example, facing the initial screen) among the plurality of screens (for example, IMG 001 to IMG 008 displayed in the application) corresponding to the successive motions of the touch. The changed screen 520 may have a number of images which is different from the number of images displayed on the first screen 500 before the change. Further, the changed screen 520 may have a number of images which is the same as the number of images displayed on the first screen 500 before the change.

Further, at least one of a plurality of feedbacks (for example, the visual feedback, the audible feedback, and the tactile feedback) provided in response to the change to the other screen 520 may be selected.

When the controller changes the first screen 500 to the other screen 520 corresponding to the first order among the plurality of screens in operation S407 of FIG. 4A, the screen changing method of the portable device ends.

When the controller detects no successive motions of the first and/or second touches moving in the down direction, operation S408 is performed.

In operation S408, successive motions of the first and/or second touches moving in an up direction are detected.

Referring to FIG. 5E, the first touch 510 successively moving in an up direction (for example, −y axis direction) may arrive at a last location 510m from the first location 510a, a second location 510k, and a third location 510l. The controller 110 may calculate the last location 510m of the first touch 510 moving in the up direction on the first edge touch screen 190b by using the edge touch screen controller 195 and the storage unit.

The last location of the first touch 510 successively moving in the up direction may be different according to a route and/or a movement distance of the successive motions of the first touch 510. For example, the last location of the first touch 510 successively moving in the up direction may be one of 510k, 510l, and 510m included along the route of the successive motions of the first touch 510. Further, when the movement distance of the successive motions of the first touch 510 is short, the last location of the first touch 510 successively moving in the up direction may be the location 510k. When the movement distance of the successive motions of the first touch 510 is long, the last location of the first touch 510 successively moving in the up direction may be the location 510m or 510l.

The controller 110 may detect the successive motions of the first touch 510 in the up direction by using an allowable slope range. The controller 110 may calculate a slope of a straight line connecting the first location 510a and the last location 510k, 510l, or 510m of the first touch 510.

Since the detection of the successive motions of the first touch 510 in the up direction using the allowable slope range in operation S408 of FIG. 4A is substantially similar (for example, a direction difference) to the detection of the successive motions of the first touch 510 in the down direction using the allowable slope range in operation S406 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the first touch 510 successive moving in the up direction may be in an area within the allowable slope range.

The controller 110 may detect the successive motions of the first touch 510 in the up direction by using a setting area (not shown). The setting area may refer to a semicircle with a radius of 3 cm having the first location 510a of the first touch 510 as the center.

Further, the route from the first location 510a to the last location of the first touch 510 successively moving in the up direction may pass through the setting area within the time interval.

Referring to FIG. 5E, the second touch 511 successively moving in an up direction (for example, −y axis direction) may arrive at a last location 511m from the first location 511a, a second location 511k, and a third location 511l. The controller 110 may calculate the last location 511m of the second touch 511 moving in the up direction on the second edge touch screen 190c by using the edge touch screen controller 195 and the storage unit.

The last location of the second touch 511 successively moving in the up direction may be different according to a route and/or a movement distance of the successive motions of the second touch 511. For example, the last location of the second touch 511 successively moving in the up direction may be one of 511k, 511l, and 511m included along the route of the successive motions of the second touch 511. Further, when the movement distance of the successive motions of the second touch 511 is short, the last location of the second touch 511 successively moving in the up direction may be the location 511k. When the movement distance of the successive motions of the second touch 511 is long, the last location of the second touch 511 successively moving in the up direction may be the location 511l or 511m.

The controller 110 may detect the successive motions of the second touch 511 in the up direction by using an allowable slope range. The controller 110 may calculate a slope of a straight line connecting the first location 511a and the last location 511k, 511l, or 511m of the second touch 511.

In an embodiment of the present disclosure, the last location of the second touch 511 successively moving in the up direction may be in an area within the allowable slope range within the time interval.

In an embodiment of the present disclosure, the last location of the second touch 511 successively moving in the up direction may be within the setting area within the time interval. Further, the route from the first location 511a to the last location of the second touch 511 successively moving in the up direction may pass through the setting area within the time interval.

The controller 110 may display a thumbnail image (not shown) in response to the first touch 510 successively moving in the up direction and/or the second touch 511 successively moving in the up direction.

Since the displaying of the thumbnail image in operation S408 of FIG. 4A is substantially similar (for example, a direction difference and an image difference) to the displaying of the thumbnail image in operation S406 of FIG. 4A, a duplicate description will be omitted.

The controller 110 may provide feedback corresponding to the arrival at the last location of the first touch 510 successively moving in the up direction to the user. The controller 110 may also provide feedback corresponding to the arrival at the last location of the second touch 511 successively moving in the up direction to the user. Further, the controller 110 may provide feedback corresponding to both the arrival at the last location of the first touch 510 successively moving in the up direction and the arrival at the last location of the second touch 511 successively moving in the up direction to the user.

The provided feedback may be provided as one of a visual feedback, an audible feedback, and a tactile feedback. Further, the controller 110 may provide a combination of the visual feedback, the audible feedback, and the tactile feedback to the user.

Since the feedback corresponding to the arrival at the last location of the first touch 510 and/or the second touch 511 successively moving in the up direction in operation S408 of FIG. 4A is substantially similar (for example, a direction difference) to the feedback corresponding to the arrival at the last location of the first touch 510 and/or the second touch 511 successively in the down direction in operation S406 of FIG. 4A, a duplicate description will be omitted.

When the successive motions of the first and second touches successively moving in the up direction are not detected, operation S410 is performed.

When the successive motions of the first and second touches successively moving in the up direction are detected, a first screen is changed to another screen corresponding to a second order among a plurality of screens in operation S409.

Referring to FIG. 5F, the controller 110 may change the first screen 500 to another screen 530 corresponding to the second order among the plurality of screens in response to the arrival at the last location of the first touch 510 successively moving in the up direction. The controller 110 may also change the first screen 500 to another screen 530 (for example, a last screen among the plurality of screens) corresponding to the second order among the plurality of screens in response to the arrival at the last location of the second touch 511 successively moving in the up direction. The controller 110 may also change the first screen 500 to another screen 530 corresponding to the second order among the plurality of screens in response to both the arrival at the last location of the first touch 510 successively moving in the up direction and the arrival at the last location of the second touch 511 successively moving in the up direction.

When the first touch 510 and the second touch 511 successively move in the up direction, the controller 110 may change the first screen 500 to another screen 530 (for example, a last screen among the plurality of screens) corresponding to the second order among the plurality of screens in response to the first arrival at the last location of the first touch before the arrival at the last location of the second touch 511. When the first touch 510 and the second touch 511 successively move in the up direction, the controller 110 may also change the first screen 500 to another screen 530 (for example, a first screen among the plurality of screens) corresponding to the first order among the plurality of screens in response to the first arrival at the last location of the second touch 511.

When the first touch 510 successively moves in the up direction, but the second touch 511 does not move, the controller 110 may change the first screen 500 to another screen 530 (for example, a last screen among the plurality of screens) corresponding to the second order among the plurality of screens in response to the arrival at the last location of the first touch 510. When the second touch 511 successively moves in the up direction, but the first touch 510 does not move, the controller 110 may change the first screen 500 to another screen 530 corresponding to the second order among the plurality of screens in response to the arrival at the last location of the second touch 511.

The other screen 530 may be an initial screen corresponding to a second order of the first screen 500 (for example, facing the last screen) among the plurality of screens (for example, IMG 201 to IMG 207 displayed in the application) corresponding to the successive motions of the touch. The changed screen 530 may have a number of images which is different from the number of images displayed on the first screen 500 before the change. Further, the changed screen 530 may have a number of images which is the same as the number of images displayed on the first screen 500 before the change.

The controller 110 may provide feedback corresponding to the change to the other screen 530. The provided feedback may be provided as one of a visual feedback, an audible feedback, and a tactile feedback. Further, the controller 110 may provide a combination of the visual feedback, the audible feedback, and the tactile feedback to the user.

Since the feedback corresponding to the change to the other screen 530 in operation S409 of FIG. 4A is substantially similar (for example, a screen difference) to the feedback corresponding to the change to the other screen 520 in operation S407 of FIG. 4A, a duplicate description will be omitted.

When the controller 110 changes the first screen 500 to the other screen 530 corresponding to the second order among the plurality of screens in operation S409 of FIG. 4A, the screen changing method of the portable device ends.

When the controller detects no successive motions of the first and/or second touches moving in the up direction, operation S410 is performed.

FIGS. 6A to 6D illustrate screens of a portable device according to another embodiment of the present disclosure.

In operation S410 of FIG. 4A, successive motions of the first and/or second touches moving in a main touch screen direction are detected.

Referring to FIG. 6A, the first touch 510 successively moving in a main touch screen direction (for example, −x axis direction) may arrive at a last location 510t from the first location 510a, a second location 510r, and a third location 510s. The controller 110 may calculate the last location 510t of the first touch 510 moving in the main touch screen direction on the first edge touch screen 190b by using the edge touch screen controller 195 and the storage unit 175.

The last location of the first touch 510 successively moving in the main touch screen direction may be different according to a route and/or a movement distance of the successive motions of the first touch 510. For example, the last location of the first touch 510 successively moving in the up direction may be one of 510r, 510s, and 510t, included along the route of the successive motions of the first touch 510. Further, when the movement distance of the successive motions of the first touch 510 is short, the last location of the first touch 510 successively moving in the up direction may be the location 510r. When the movement distance of the successive motions of the first touch 510 is long, the last location of the first touch 510 successively moving in the up direction may be the location 510s or 510t.

The successive motions of the first touch 510 successively moving in the main touch screen direction may correspond to a curved line. For example, the route of the successive motions of the first touch 510 successively moving in the main touch screen direction may correspond to a curved line following a curvature of the first edge touch screen 190b.

The controller 110 may detect the successive motions of the first touch 510 in the up direction by using an allowable slope range. The controller 110 may calculate a slope of a straight line (or arc) connecting the first location 510a and the last location 510r, 510s, or 510t, of the first touch 510.

Since the detection of the successive motions of the first touch 510 in the main touch screen direction using the allowable slope range in operation S410 of FIG. 4A is substantially similar (for example, a direction difference) to the detection of the successive motions of the first touch 510 in the down direction using the allowable slope range in operation S406 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the first touch 510 successively moving in the main touch screen direction may be in an area within the allowable slope range.

The controller 110 may detect the successive motions of the first touch 510 in the main touch screen direction by using a setting area. The setting area may refer to a semicircle with a radius of 3 cm having the first location 510a of the first touch 510 as the center in the y axis direction

Since the detection of the successive motions of the first touch 510 in the main touch screen direction using the setting area in operation S410 of FIG. 4A is substantially similar (for example, a direction difference) to the detection of the successive motions of the first touch 510 in the down direction using the setting area in operation S406 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the first touch 510 successively moving in the main touch screen direction may be within the setting area. Further, the route from the first location 510a to the last location of the first touch 510 successively moving in the main touch screen direction may pass through the setting area.

The controller 110 may detect the successive motions of the first touch 510 in the main touch screen direction based on a combination of a time interval as well as the allowable slope range and the setting area. For example, the controller 110 may detect the successive motions of the first touch 510 in the main touch screen direction by using a combination of the allowable slope range and the time interval, and a combination of the setting area and the time interval.

Since the detection of the successive motions of the first touch 510 in the main touch screen direction using the combination of the allowable slope range and the time interval, and the combination of the setting area and the time interval in operation S410 of FIG. 4A is substantially similar (for example, a direction difference) to the detection of the successive motions of the first touch 510 in the down direction using the combination of the allowable slope range and the time interval, and the combination of the setting area and the time interval in operation S406 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the first touch 510 successively moving in the main touch screen direction may be in an area within the allowable slope range within the time interval.

In an embodiment of the present disclosure, the last location of the first touch 510 successively moving in the main touch screen direction may be within the setting area within the time interval. Further, the route from the first location 510a to the last location of the first touch 510 successively moving in the main touch screen direction may pass through the setting area within the time interval.

Referring to FIG. 6A, the second touch 511 successively moving in a main touch screen direction (for example, −x axis direction) may arrive at the last location 511t from the first location 511a, a second location 511r, and a third location 511s. The controller 110 may calculate the last location 511t of the second touch 511 moving in the main touch screen direction on the second edge touch screen 190c by using the edge touch screen controller 195 and the storage unit 175.

The last location of the second touch 511 successively moving in the main touch screen direction may be different according to a route and/or a movement distance of the successive motions of the second touch 511. For example, the last location of the second touch 511 successively moving in the main touch screen direction may be one of 511r, 511s, and 511t, included along the route of the successive motions of the second touch 511. Further, when the movement distance of the successive motions of the second touch 511 is short, the last location of the second touch 511 successively moving in the main touch screen direction may be the location 511r. Further, when the movement distance of the successive motions of the second touch 511 is long, the last location of the second touch 511 successively moving in the main touch screen direction may be the location 511s or 511t.

The successive motions of the second touch 511 successively moving in the main touch screen direction may be a curved line. The route of the successive motions of the second touch 511 successively moving in the main touch screen direction may correspond to a curved line following a curvature of the second edge touch screen 190c.

The controller 110 may detect the successive motions of the second touch 511 in the up direction by using an allowable slope range. The controller 110 may calculate a slope of a straight line connecting the first location 511a and the last location 511r, 511s, or 511t of the second touch 511.

Since the detection of the successive motions of the second touch 511 in the main touch screen direction using the allowable slope range in operation S410 of FIG. 4A is substantially similar (for example, a direction difference) to the detection of the successive motions of the second touch 511 in the down direction using the allowable slope range in operation S406 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the second touch 511 successively moving in the main touch screen direction may be in an area within the allowable slope range.

The controller 110 may detect the successive motions of the second touch 511 in the main touch screen direction by using a setting area. The setting area may refer to a semicircle with a radius of 3 cm having the first location 511a of the second touch 511 as the center in the y axis direction.

Since the detection of the successive motions of the second touch 511 in the main touch screen direction using the setting area in operation S410 of FIG. 4A is substantially similar (for example, a direction difference) to the detection of the successive motions of the second touch 511 in the down direction using the setting area in operation S406 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the second touch 511 successively moving in the main touch screen direction may be within the setting area. Further, the route from the first location 511a to the last location of the second touch 511 successively moving in the main touch screen direction may pass through the setting area.

The controller 110 may detect the successive motions of the second touch 511 in the main touch screen direction based on a combination of a time interval as well as the allowable slope range and the setting area. For example, the controller 110 may detect the successive motions of the second touch 511 in the main touch screen direction by using a combination of the allowable slope range and the time interval and a combination of the setting area and the time interval.

Since the detection of the successive motions of the second touch 511 in the main touch screen direction using the combination of the allowable slope range and the time interval and the combination of the setting area and the time interval in operation S410 of FIG. 4A is substantially similar (for example, a direction difference) to the detection of the successive motions of the first touch 510 in the down direction using the combination of the allowable slope range and the time interval and the combination of the setting area and the time interval in operation S406 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the second touch 511 successively moving in the main touch screen direction may be in an area within the allowable slope range within the time interval.

In an embodiment of the present disclosure, the last location of the second touch 511 successively moving in the main touch screen direction may be within the setting area within the time interval. Further, the route from the first location 511a to the last location of the second touch 511 successively moving in the main touch screen direction may pass through the setting area within the time interval.

The controller 110 may provide feedback corresponding to the arrival at the last location of the first touch 510 successively moving in the main touch screen direction to the user. The controller 110 may also provide feedback corresponding to the arrival at the last location of the second touch 511 successively moving in the main touch screen direction to the user. Further, the controller 110 may provide feedback corresponding to both the arrival at the last location of the first touch 510 successively moving in the main touch screen direction and the arrival at the last location of the second touch 511 successively moving in the main touch screen direction to the user.

The provided feedback may be provided as one of a visual feedback, an audible feedback, and a tactile feedback. Further, the controller 110 may provide a combination of the visual feedback, the audible feedback, and the tactile feedback to the user.

Referring to FIG. 6B, the visual feedback may be feedback for reducing the first screen 500 to be a reduced screen 603 having a determined size (for example, 50% of the first screen 500, but values can be changed). The controller 110 may gradually reduce (for example, 500601602603) the first screen 500 to be the reduced screen 603 at one of a constant velocity and a non-constant velocity. The reduced screen 603 may be displayed to overlap the first screen 500. The reduced screen 603 may have one or more transparent regions (which can be changed, combined or configured in any number of ways).

The number of intermediate reduced screens 601 and 602 displayed during the reduction process from the first screen 500 to the reduced screen 603 is one example, and it is easily understood by those skilled in the art that the number of intermediate reduced screens can be changed.

Referring to FIG. 6C, the reduced screen 603 may move or be moved to one side of the edge touch screen 190. When the reduced screen 603 moves to one side of the edge touch screen 190, the controller 110 may further reduce the reduced screen 603 and gradually move the reduced screen 603. Further, the reduced screen 603 may move to the one side of the edge touch screen 190 at one of the constant velocity and the non-constant velocity at which reduction occurred.

The one side of the edge touch screen 190 to which the reduced screen 603 can move may include an upper portion, a lower portion, a left side, or a right side and may, for example, correspond to an orientation of the portable device 100.

When the successive motions of the first and second touches successively moving in the main touch screen direction are not detected at operation S410, the screen changing method of the portable device ends.

In operation S411 of FIG. 4A, the first screen is captured.

Referring to FIG. 6D, the controller 110 captures the first screen 500 in response to the arrival at the last location of the first touch 510 successively moving in the main touch screen direction. The controller 110 may also capture the first screen 500 in response to the arrival at the last location of the second touch 511 successively moving in the main touch screen direction. The controller 110 may also capture the first screen 500 in response to both the arrival at the last location of the first touch 510 successively moving in the main touch screen direction and the arrival at the last location of the second touch 511 successively moving in the main touch screen direction.

When the first touch 510 and the second touch 511 successively move in the main touch screen direction, the controller 110 may capture the first screen 500 in response to the first arrival at the last location of the first touch 510. Further, when the first touch 510 and the second touch 511 successively move in the main touch screen direction, the controller 110 may capture the first screen 500 in response to the first arrival at the last location of the second touch 511.

When the first touch 510 successively moves in the main touch screen direction, but the second touch 511 does not move, the controller 110 may capture the first screen 500 in response to the arrival at the last location of the first touch 510. When the second touch 511 successively moves in the main touch screen direction, but the first touch 510 does not move, the controller 110 may capture the first screen 500 in response to the arrival at the last location of the second touch 511.

Referring to FIG. 6D, when the first screen 500 is captured, the controller 110 may display the first screen 500. When an output of feedback corresponding to the arrival at the last location of the first touch 510 successively moving in the main touch screen direction is completed, the controller 110 may also display the first screen 500.

The controller 110 may provide the feedback corresponding to the capturing of the first screen 500. The provided feedback may be provided as one of a visual feedback, an audible feedback, and a tactile feedback. Further, the controller 110 may provide a combination of the visual feedback, the audible feedback, and the tactile feedback to the user.

Since the feedback corresponding to the capturing of the first screen 500 in operation S411 of FIG. 4A is substantially similar (for example, screen capturing) to the feedback corresponding to the change to the other screen 520 in operation S407 of FIG. 4A, a duplicate description will be omitted.

When the controller 110 captures the first screen 500 in operation S411 of FIG. 4A, the screen changing method of the portable device ends.

FIG. 4B is a flowchart illustrating a screen changing method of a portable device according to another embodiment of the present disclosure.

FIGS. 7A to 7D illustrate screens of a portable device according to an embodiment of the present disclosure.

In operation S431 of FIG. 4B, a third screen is displayed in a third application.

Referring to FIG. 7A, a second screen 700 is displayed on the edge touch screen 190.

The controller 110 may execute a second application and display the second screen 700 in response to a user input (not shown). The second screen 700 may display a title bar (not shown) for showing a name of the second application (for example, a game market) executed in the portable device 100 and one or more games (for example, games 701a, 701b, 701c and 701d) displayed through the second application.

The second application executed in the portable device 100 may be one of various applications (for example, a messenger, an SNS, and the like), but the present disclosure is not limited thereto.

The user may select one of the displayed games and install the selected game in the portable device. Further, the user may end the second application.

Referring to FIG. 7B, a third screen 705 is displayed on the edge touch screen 190.

The controller 110 may execute a third application and display the third screen 705 in response to a user input (not shown). The third screen 705 may display a title bar (not shown) for showing a name of the third application (for example, a photo album) executed in the portable device 100 and one or more photos (for example, photos 706a, 706b, 706c, 706d, 706e, 706f, 706g, 706h, 706i, 706j, 706k and 706l) displayed through the third application.

The third application executed in the portable device 100 may be one of various applications (for example, a messenger, an SNS, and the like) but the present disclosure is not limited thereto.

In operation S432 of FIG. 4B, an eleventh touch is detected on the main touch screen.

Referring to FIG. 7C, the user conducts the eleventh touch 710 on the main touch screen 190a. The controller 110 may detect the eleventh touch 710 by using the edge touch screen 190 and the edge touch screen controller 195. Further, the controller 110 may detect the eleventh touch 710 by using the main touch screen 190a and the edge touch screen controller 195. The controller 110 may calculate an eleventh touch location 710a (for example, X11 and Y11 coordinates) corresponding to the eleventh touch 710 by using an electrical signal received from the edge touch screen controller 195.

The controller 110 may store eleventh touch location information corresponding to the eleventh touch location 710a in the storage unit 175. The stored eleventh touch location information may include a touch ID, a touch location, a touch detection time, or touch information (for example, a touch pressure, touch direction, and touch duration time) for history management.

Since the detection of the eleventh touch on the main touch screen in operation S432 of FIG. 4B is substantially similar (for example, a difference in the detected touch location) to the detection of the first touch on the first edge touch screen in operation S402 of FIG. 4A, a duplicate description will be omitted.

In operation S433 of FIG. 4B, a twelfth touch is detected on the main touch screen.

Referring to FIG. 7C, the user conducts the twelfth touch 711 on the main touch screen 190a. The controller 110 may detect the twelfth touch 711 by using the edge touch screen 190 and the edge touch screen controller 195. Further, the controller 110 may detect the twelfth touch 711 by using the main touch screen 190a and the edge touch screen controller 195. The controller 110 may calculate a twelfth touch location 711a (for example, X12 and Y12 coordinates) corresponding to the twelfth touch 710 by using an electrical signal received from the edge touch screen controller 195.

The controller 110 may store twelfth touch location information corresponding to the twelfth touch location 711a in the storage unit 175. The stored twelfth touch location information may include a touch ID, a touch location, a touch detection time, or touch information (for example, a touch pressure, touch direction, and touch duration time) for history management.

Since the detection of the twelfth touch on the main touch screen in operation S433 of FIG. 4B is substantially similar (for example, a difference in the detected touch location) to the detection of the eleventh touch on the main edge touch screen in operation S403 of FIG. 4A, a duplicate description will be omitted.

In operation S434 of FIG. 4B, successive motions of the eleventh touch are detected.

Referring to FIG. 7C, the controller 110 may detect (or calculate) successive motions (for example, a plurality of X and Y coordinates corresponding to the successive touches) of the eleventh touch 710 by using the main touch screen 190a and the edge touch screen controller 195. The successive motions of the eleventh touch 710 may be stored in the storage unit 175 under a control of the controller 110. The number of touches contacted on the main touch screen 190a may be singular or plural.

The successive motions (for example, a movement from a first location 710a, a second location 710b, and a third location 710c, to a last location 710d) of the eleventh touch 710 may refer to an eleventh touch gesture detected on the main touch screen 190a. The successive motions (for example, the movement from the first location 710a to the last location 710d) of the eleventh touch 710 may refer to an eleventh touch gesture detected on the main touch screen 190a in a left direction (for example, −x axis direction).

The successive motions (for example, the movement from the first location 710a to the last location 710d) of the eleventh touch 710 may mean that the contact between the main touch screen 190a and the eleventh touch 710 is continuously maintained. Further, in the successive motions of the eleventh touch 710, the contact on the main touch screen 190a may be touch-released at the last location 710d.

The successive motions (for example, the movement from the first location 710a to the last location 710d) of the eleventh touch 710 may refer to an eleventh touch gesture detected from the main touch screen 190a to the first edge touch screen 190b beyond the virtual line 190b1. The successive motions (for example, the movement from the first location 710a to the last location 710d) of the eleventh touch 710 may mean that the contact of the eleventh touch 710 from the main touch screen 190a to the first edge touch screen 190b is continuously maintained. Further, in the successive motions of the eleventh touch 710, the contact on the first edge touch screen 190b may be touch-released at the last location 710d.

Referring to FIG. 7C, the successive motions of the eleventh touch 710 in the left direction from the main touch screen 190a may include drag, drag & drop, flick, or swipe.

In operation S435 of FIG. 4B, successive motions of the twelfth touch are detected.

Referring to FIG. 7C, the controller 110 may detect (or calculate) successive motions (for example, a plurality of X and Y coordinates corresponding to the successive touches) of the twelfth touch 711 by using the main touch screen 190a and the edge touch screen controller 195. The successive motions of the twelfth touch 711 may be stored in the storage unit 175 under a control of the controller 110. The number of touches contacted on the main touch screen 190a may be singular or plural.

The successive motions (for example, a movement from a first location 711a, a second location 711b, and a third location 711c, to a last location 711d) of the twelfth touch 711 may refer to a twelfth touch gesture detected on the main touch screen 190a. The successive motions (for example, the movement from the first location 711a to the last location 711d) of the twelfth touch 711 may refer to a twelfth touch gesture detected on the main touch screen 190a in a right direction (for example, x axis direction).

The successive motions (for example, the movement from the first location 711a to the last location 711d) of the twelfth touch 711 may mean that the contact between the main touch screen 190a and the twelfth touch 711 is continuously maintained. Further, in the successive motions of the twelfth touch 711, the contact on the main touch screen 190a may be touch-released at the last location 711d.

The successive motions (for example, the movement from the first location 711a to the last location 711d) of the twelfth touch 711 may refer to a twelfth touch gesture detected from the main touch screen 190a to the second edge touch screen 190c beyond the virtual line 190c1. The successive motions (for example, the movement from the initial location 711a to the last location 711d) of the twelfth touch 711 may mean that the contact of the twelfth touch 711 from the main touch screen 190a to the second edge touch screen 190c is continuously maintained. Further, in the successive motions of the twelfth touch 711, the contact on the second edge touch screen 190c may be touch-released at the last location 711d.

Referring to FIG. 7C, the successive motions of the twelfth touch 711 in the left direction from the main touch screen 190a may include drag, drag & drop, flick, or swipe.

In operation S436 of FIG. 4B, the successive motions of the eleventh touch are detected on the first edge touch screen, and the successive motions of the twelfth touch are detected on the second edge touch screen.

Referring to FIG. 7C, the eleventh touch 710 successively moving in the left direction (for example, −x axis direction) may arrive at the last location 710d from the first location 710a. The controller 110 may calculate the last location 710d of the eleventh touch 710 moving in the left direction on the first edge touch screen 190b by using the edge touch screen controller 195 and the storage unit 175.

The controller 110 may detect the successive motions of the eleventh touch 710 in the left direction by using a setting area (not shown). The setting area may refer to a semicircle with a radius of 3 cm having the intersection point at the third location 710c of the eleventh touch 710 as the center. The semicircle with the radius of 3 cm in an x axis direction may be limited by the edge area 190b2. The radius of the setting area may be equal to or smaller than 1 cm, equal to or smaller than 2 cm, equal to or smaller than 3 cm, equal to or smaller than 4 cm, or equal to or smaller than 5 cm. The aforementioned setting area is only an embodiment, and the present disclosure is not limited thereto.

In an embodiment of the present disclosure, the last location of the eleventh touch 710 successively moving in the left direction may be within the setting area. Further, the route from the first location 710a to the last location of the eleventh touch 710 successively moving in the left direction may pass through the setting area.

The controller 110 may detect the successive motions of the eleventh touch 710 in the left direction based on a combination of the allowable slope range, the setting area, and a time interval. For example, the controller 110 may detect the successive motions of the eleventh touch 710 in the down direction by using a combination of the allowable slope range and the time interval, and a combination of the setting area and the time interval.

The time interval may refer to an interval between the time of the first location 710a of the eleventh touch 710, and the time of the last location 710d.

In an embodiment of the present disclosure, the last location of the twelfth touch 711 successively moving in the right direction may be within the setting area within the time interval. Further, the route from the first location 711a to the last location of the twelfth touch 711 successively moving in the right direction may pass through the setting area within the time interval.

In operation S437 of FIG. 4B, the second screen of the second application, which is executed before the execution of the third application, is displayed.

Referring to FIG. 7D, the controller 110 displays the second screen 700 of the second application, which was executed before the execution of the third application, in response to the arrival of the eleventh touch 710 at the first edge touch screen 190b of the edge touch screen 190 as in FIG. 7A. The second screen 700 displays a title bar (not shown) for showing a name of the second application (for example, a game market) executed in the portable device 100 and one or more games (for example, games 701a, 701b, 701c and 701d) displayed through the second application. The controller 110 displays the second screen of the second application, which is executed before the execution of the third application, in response to the arrival of the twelfth touch 711 at the second edge touch screen 190c of the edge touch screen 190.

The controller 110 may display the second screen 700 of the second application, which is executed before the execution of the third application, in response to the arrival of the eleventh touch 710 at the first edge touch screen 190b of the edge touch screen 190 and the arrival of the twelfth touch 711 at the second edge touch screen 190c of the edge touch screen 190.

When the eleventh touch 710 in the left direction and the twelfth touch 711 in the right direction successively move, the controller 110 may display the second screen 700, which is executed before the execution of the third application, in response to the first arrival of the eleventh touch 710 at the first edge touch screen 190b. Further, when the eleventh touch 710 in the left direction and the twelfth touch 711 in the right direction successively move, the controller 110 may display the second screen 700, which is executed before the execution of the third application, in response to the first arrival of the twelfth touch 711 at the second edge touch screen 190c.

When the eleventh touch 710 successively moves in the left direction, but the twelfth touch 711 does not move, the controller 110 may display the second screen 700, which is executed before the execution of the third application, in response to the first arrival of the eleventh touch 710 at the first edge touch screen 190b. When the twelfth touch 711 successively moves in the right direction, but the eleventh touch does not move, the controller 110 may display the second screen 700, which is executed before the execution of the third application, in response to the first arrival of the twelfth touch 711 at the second edge touch screen 190c.

The controller 110 may provide feedback corresponding to the displaying of the second screen 700 of the second application. The provided feedback may be provided as one of a visual feedback, an audible feedback, and a tactile feedback. Further, the controller 110 may provide a combination of the visual feedback, the audible feedback, and the tactile feedback to the user.

Since the feedback corresponding to the displaying of the second screen 700 of the second application in operation S437 of FIG. 4B is substantially similar (for example, a screen difference) to the feedback corresponding to the change to the other screen 520 in operation S407 of FIG. 4A, a duplicate description will be omitted.

When the controller 110 changes the screen to the second screen of the second application in operation S437 of FIG. 4B, the screen changing method of the portable device ends.

FIG. 4C is a flowchart illustrating a screen changing method of a portable device according to another embodiment of the present disclosure.

In operation S451 of FIG. 4C, a fourth screen is displayed on the main touch screen and a first edge screen is displayed on the first edge touch screen.

Referring to FIGS. 8A and 8B, a fourth screen 800 is displayed on the main touch screen 190a of the portable device 100 and a first edge screen 820 is displayed on the first edge touch screen 190b. FIG. 8A illustrates a screen display of the main edge touch screen and at opposite sides thereof, illustrates several screen displays of the first (left) and second (right) edge touch screen. The screen displays of the first (left) and second (right) edge touch screen are rotated and presented in a flat manner to simplify descriptions. In contrast to FIG. 1, the positions of the first edge touch screen 190b and the second edge touch screen 190c in FIGS. 8A to 8F are reversed.

The controller 110 may display edge screens 820, 821, 822, 823 and 824 on the edge touch screens 190b and 190c, as well as the fourth screen 800 on the main touch screen 190a.

The plurality of edge screens 820 to 824 displayed on the edge touch screens 190b and 190c may be screens of applications executed in the portable device 100 or screens of widgets. The edge screens 820 to 824 may have sizes corresponding to the sizes of the edge touch screens 190b and 190c.

For example, a music edge screen corresponding to the first edge screen 820 may be a reduced control panel of a music player (not shown). The first edge screen 820 may include a play button 820a, a next button 820b, or a previous button 820c. The music player may be controlled through the first edge screen 820. The buttons displayed on the first edge screen 820 are only examples, and the present disclosure is not limited thereto. Further, the first edge screen 820 may be a reduced control panel of a video player (not shown). When the video player is played, the reduced control panel may be displayed on the edge touch screen 190b or 190c.

A social network edge screen 821 corresponding to the second edge screen may be a screen of a SNS application. A received message 821a of the SNS application received through the second edge screen 821 may be displayed.

A preference edge screen 822 corresponding to a third edge screen may display short cut icons 822a, 822b, 822c, 822d, 822e, 822f and 822g corresponding to preferred applications among the applications installed in the portable device 100. When one of the short cut icons 822a to 822g displayed on the third edge screen 822 is selected, the controller 110 may display an application corresponding to the short cut icon on the main touch screen 190a.

A stock edge screen 823 corresponding a fourth edge screen may display information of a preferred item 823a, such as in a stock application. The information (or quotes) may include an offer price, a bid price, a current price, or a price compared to the previous day's price.

A battery edge screen 824 corresponding to a fifth edge screen may display a residual battery amount 824a. Further, the battery edge screen 824 may display an available battery use time (for example, 15 min).

The controller 110 may revolve the plurality of edge screens 820 to 824 according to a user input. For example, two edge screens may be displayed on the two edge touch screens 190b and 190c. The remaining edge screens, which are not displayed, may be revolved to take the place of previous screens in order for each screen to be displayed according to one of a repeating first order (for example, 820821822823824820821822823824) and a repeating second order (for example, 824823822821820824823822821820).

When the edge screens are revolved according to the first order, the controller 110 may sequentially display the edge screens from the first edge screen 820 to the fifth edge screen 824 on the two edge touch screens 190b and 190c in accordance with a user input. When the edge screens are revolved according to the first order, the controller 110 may sequentially display the edge screens from the first edge screen 820 to the fifth edge screen 824 on the two edge touch screens 190b and 190c in accordance with a user input.

Referring to FIG. 8B, the controller 110 may display the fourth screen 800 on the main touch screen 190a. The controller 110 may display the first edge screen 820 on the first edge touch screen 190b and the second edge screen 821 on the second edge touch screen 190c. The edge touch screens and the edge screens displayed on the edge touch screens are only examples, and it is easily understood by those skilled in the art that the edge touch screens and the edge screens can be variously changed.

In operation S452 of FIG. 4B, a twenty first touch is detected on the first edge touch screen.

Referring to FIG. 8C, the user conducts a twenty first touch 810 on the first edge touch screen 190b. The controller 110 may detect the twenty first touch 810 by using the edge touch screen 190 and the edge touch screen controller 195. Further, the controller 110 may detect the twenty first touch 810 by using the first edge touch screen 190b and the edge touch screen controller 195. The controller 110 may calculate a twenty first touch location 810a (for example, X21 and Y21 coordinates) corresponding to the twenty first touch 810 by using an electrical signal received from the edge touch screen controller 195.

The controller 110 may store twenty first touch location information corresponding to the twenty first touch location 810a in the storage unit 175. The stored twenty first touch location information may include a touch ID, a touch location, a touch detection time, or touch information (for example, a touch pressure, touch direction, and touch duration time) for history management.

Since the detection of the twenty first touch in operation S452 of FIG. 4C is substantially similar (for example, a touch difference) to the detection of the first touch in operation S402 of FIG. 4A, a duplicate description will be omitted.

In another embodiment of the present disclosure, when the portable device 100 is grasped by the user's left hand (or right hand), the twenty first touch 810 may be input by the thumb. Further, another touch 815 may be detected on the second edge touch screen 190c by one of the remaining fingers except for the thumb. Since the detection of the other touch 815 and calculation of a location 815a of the other touch are substantially similar (for example, a touch difference) to the detection of the twenty first touch 810 and calculation of a location 810a of the twenty first touch, a duplicate description will be omitted.

When successive motions of the twenty first touch 810 are detected, the portable device 100 may be supported by the other touch 815 (for example, a reaction of the successive motions of the twenty first touch). Further, when the successive motions of the twenty first touch 810 are detected, the other touch 815 may maintain the contact on the second edge touch screen 190c.

In operation S453 of FIG. 4C, the successive motions of the twenty first touch are detected.

Referring to FIG. 8C, the controller 110 may detect (or calculate) the successive motions (for example, a plurality of X and Y coordinates corresponding to the successive touches) of the twenty first touch 810 by using the first edge touch screen 190b and the edge touch screen controller 195. The successive motions of the twenty first touch 810 may be stored in the storage unit 175 under a control of the controller 110. The number of touches contacted on the first edge touch screen 190b may be singular or plural.

The successive motions (for example, a movement from a first location 810a, a second location 810b, and a third location 810c, to a last location 810d) of the twenty first touch 810 may refer to a twenty first touch gesture detected on the first edge touch screen 190b. The successive motions (for example, the movement from the first location 810a to the last location 810d) of the twenty first touch 810 may refer to a twenty first touch gesture detected on the first edge touch screen 190b in a left direction (for example, −x axis direction).

The successive motions (for example, the movement from the first location 810a to the last location 810d) of the twenty first touch 810 may mean that the contact between the first edge touch screen 190b and the twenty first touch 810 is continuously maintained. Further, in the successive motions of the twenty first touch 810, the contact on the first edge touch screen 190b may be touch-released at the last location 810d.

Since the detection of the successive motions of the twenty first touch in operation S453 of FIG. 4C is substantially similar (for example, a touch difference) to the detection of the successive motions of the first touch in operation S404 of FIG. 4A, a duplicate description will be omitted.

In operation S454 of FIG. 4C, the twenty first touch arrives at the main touch screen.

Referring to FIG. 8C, the twenty first touch 810 successively moving in the main touch screen direction (for example, −x axis direction) may arrive at the last location 810d from the first location 810a. The controller 110 may calculate the last location 810d of the twenty first touch 810 moving in the main touch screen direction on the main touch screen 190a by using the edge touch screen controller 195 and the storage unit 175.

The last location of the twenty first touch 810 successively moving in the main touch screen direction may be different according to a route and/or a movement distance of the successive motions of the twenty first touch 810. For example, the last location of the twenty first touch 810 successively moving in the left direction may be one of 810b, 810c, and 810d, included along the route of the successive motions of the twenty first touch 810. Further, when the movement distance of the successive motions of the twenty first touch 810 is short, the last location of the twenty first touch 810 successively moving in the left direction may be the location 810b. When the movement distance of the successive motions of the twenty first touch 810 is long, the last location of the twenty first touch 810 successively moving in the left direction may be the location 810d or 810c.

The route of the successive motions of the twenty first touch 810 moving from the first edge touch screen 190b to the main touch screen 190a may be a curved line. The route of the twenty first touch 810 successively moving from the first edge touch screen 190b to the main touch screen 190a may be a curved line following a curvature of the first edge touch screen 190b.

The controller 110 may detect the arrival of the twenty first touch 810 moving in the left direction at the main touch screen 190a by using an allowable slope range. The controller 110 may calculate a slope of a straight line (or arc) connecting the first location 810a and the last location 810b, 810c, or 810d of the twenty first touch 810.

Since the detection of the arrival of the twenty first touch 810 at the main touch screen 190a using the allowable slope range in operation S454 of FIG. 4C is substantially similar to the detection of the successive motions of the first touch 510 in the left direction using the allowable slope range in operation S410 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the twenty first touch 810 successively moving in the direction of the main touch screen 190a may be in an area within the allowable slope range. In an embodiment of the present disclosure, the last location of the twenty first touch 810 successively moving in the main touch screen direction may be on the main touch screen 190a.

The controller 110 may detect the arrival of the twenty first touch 810 moving in the left direction at the main touch screen 190a by using a setting area. The setting area may refer to a semicircle with a radius of 3 cm having the first location 810a of the twenty first touch 810 as the center in a y axis direction.

Since the detection of the arrival of the twenty first touch 810 moving in the left direction at the main touch screen 190a using the setting area in operation S454 of FIG. 4C is substantially similar to the detection of the arrival of the last location of the first touch 510 successively moving in the left direction in operation S410 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the twenty first touch 810 successively moving in the main touch screen direction may be within the setting area. In an embodiment of the present disclosure, the last location of the twenty first touch 810 successively moving in the main touch screen direction may be on the main touch screen 190a. Further, the route from the first location 810a to the last location 810d of the twenty first touch 810 successively moving in the main touch screen direction may pass through the setting area.

The controller 110 may detect the successive motions of the twenty first touch 810 in the main touch screen direction based on a combination of a time interval as well as the allowable slope range and the setting area. For example, the controller 110 may detect the successive motions of the twenty first touch 810 in the main touch screen direction by using a combination of the allowable slope range and the time interval and a combination of the setting area and the time interval.

Since the detection of the arrival of the twenty first touch 810 at the main touch screen 190a using the combination of the allowable slope range and the time interval and the combination of the setting area and the time interval in operation S454 of FIG. 4C is substantially similar to the detection of the arrival of the last location of the first touch 510 successively moving in the left direction using the combination of the allowable slope range and the time interval, and the combination of the setting area and the time interval in operation S410 of FIG. 4A, a duplicate description will be omitted.

In an embodiment of the present disclosure, the last location of the twenty first touch 810 on the main touch screen 190a may be in an area within the allowable slope range within the time interval.

In an embodiment of the present disclosure, the last location of the twenty first touch 810 on the main touch screen 190a may be within the setting area within the time interval. Further, the route from the first location 810a to the last location of the twenty first touch 810 on the main touch screen 190a may pass through the setting area within the time interval.

The controller 110 may provide feedback corresponding to the arrival of the twenty first touch 810 at the main touch screen 190a to the user. The provided feedback may be provided as one of a visual feedback, an audible feedback, and a tactile feedback. Further, the controller 110 may provide a combination of the visual feedback, the audible feedback, and the tactile feedback to the user.

Since the feedback corresponding to the arrival of the twenty first touch 810 at the main touch screen 190a in operation S454 of FIG. 4C is substantially similar (for example, a direction difference) to the feedback corresponding to the arrival at the last location of the first touch 510 successively moving in the left direction in operation S410 of FIG. 4A, a duplicate description will be omitted.

Referring to FIG. 8E, in another embodiment of the present disclosure, a twenty second touch 811 may be detected on the second edge touch screen 190c. Successive motions (for example, from a first location 811a, a second location 811b, a third location 811c, to a last location 811d) of the twenty second touch 811 may be detected. The arrival of the twenty second touch 811 successively moving may be detected on the main touch screen 190a.

Since the detection of the arrival of the twenty second touch 811 at the main touch screen 190a from the second edge touch screen 190c in FIG. 8E is substantially similar (for example, a touch difference) to the detection of the arrival of the twenty second touch 811 at the main touch screen 190a from the first edge touch screen 190b in FIG. 8C, a duplicate description will be omitted.

In operation S455 of FIG. 4C, the first edge screen is displayed on the second edge touch screen and the third edge screen is displayed on the first edge touch screen.

Referring to FIG. 8D, the controller 110 may display the first edge screen 820 on the second edge touch screen 190c and the fifth edge screen 824 on the first edge touch screen in response to the arrival of the twenty first touch 810 at the main touch screen 190a.

The controller 110 may display the first edge screen 820 displayed on the first edge touch screen 190b on the second edge touch screen 190c. Further, the controller 110 may display the fifth edge screen 824 on the first edge touch screen 190b in response to the movement of the first edge screen 820 displayed on the first edge touch screen 190b to the second edge touch screen 190c.

The controller 110 may provide feedback corresponding to the change to the other screen. The provided feedback may be provided as one of a visual feedback, an audible feedback, and a tactile feedback. Further, the controller 110 may provide a combination of the visual feedback, the audible feedback, and the tactile feedback to the user.

Since the feedback corresponding to the displaying of the other edge screen 821 in operation S455 of FIG. 4C is substantially similar (for example, a screen difference) to the feedback corresponding to the change to the other screen 520 in operation S407 of FIG. 4A, a duplicate description will be omitted.

Referring to FIG. 8F, in another embodiment of the present disclosure, the controller 110 may display the third edge screen 822 on the second edge touch screen 190c and the second edge screen 821 on the first edge touch screen 190b in response to the arrival of the successively moving twenty second touch 811 at the main touch screen 190a.

When the controller 110 displays the other edge screen 821 in response to the successive motions of the twenty first touch 810 in operation S455 of FIG. 4C, the screen changing method of the portable device ends.
