The transmission interface 117 is coupled wiredly or wirelessly to the computer 13.

For convenience of explanation, the peripheral device 15 could include a lock key 151, an unlock key 153, a transmission module 155 and an encoding module 157, but the peripheral device 15 may also include other related circuitry. The lock key 151 and the unlock key 153 are coupled to the encoding module 157, and the encoding module 157 is coupled to the transmission module 155. The transmission module 155 is coupled wiredly or wirelessly to the computer 13.

The processing module 115 of the keyboard device 11, for example, could be a processing circuit with controllers and related circuits. In the present embodiment, the processing module 115 is exemplified by the keyboard controller 1153 and the decoding module 1151. The decoding module 1151, for example, could be a software or hardware decoder, and the encoding module 157, for example, also could be a software or hardware encoder, to which the present invention is not limited.

When the user wants to lock the specific key of the keyboard device 11 to avoid touching in game play or a software operation, the user can operate the lock key 151 of the peripheral device 15 to make the encoding module 157 generating a locking signal according to the keyboard indicator light control instruction outputted from the computer 13 to the keyboard device 11. The encoding module 157 wiredly or wirelessly transmits the locking signal to the computer 13 through the transmission module 155. Since the locking signal is encoded by the keyboard indicator light control instruction, the computer 13 can directly transmit the locking signal to the keyboard device 11 when receiving it from the peripheral device 15.

The processing module 115 of the keyboard device 11 wiredly or wirelessly receives the locking signal through the transmission interface 117, and then the decoding module 1151 decodes the locking signal. The keyboard controller 1153 locks the specific key of the key module 111 according to the decoded result of the decoding module 1151 to make the locked key stop outputting signal to the computer 13, thereby achieving the purpose of using a peripheral device 15 to lock a specific key of the keyboard device 11.

When the user wants to unlock the locked key of the keyboard device 11, the user can operate the unlock key 153 of the peripheral device 15 to make the encoding module 157 generate an unlocking signal according to the keyboard indicator light control instruction outputted from the computer 13 to the keyboard device 11. The encoding module 157 wiredly or wirelessly transmits the unlocking signal to the computer 13 through the transmission module 155. Since the unlocking signal is encoded by the keyboard indicator light control instruction, the computer 13 can directly transmit the unlocking signal to the keyboard device 11 when receiving it from the peripheral device 15.

The processing module 115 of the keyboard device 11 wiredly or wirelessly receives the unlocking signal through the transmission interface 117, and then the decoding module 1151 decodes the unlocking signal. The keyboard controller 1153 unlocks the locked key of the key module 111 according to the decoded result of the decoding module 1151 to make the locked key resume outputting signal to the computer 13, thereby achieving the purpose of using a peripheral device 15 to unlock the locked key of the keyboard device 11.

The locking signal and the unlocking signal is encoded by the keyboard indicator light control instruction outputted from the computer 13 to the keyboard device 11, so that the computer 13 can directly transmit the locking signal and the unlocking signal to the keyboard device 11 when receiving them from the peripheral device 15. The detailed coding will be described in the following description.

Referring to FIG. 3A, FIG. 3A is a schematic diagram of the signal code according to one embodiment of the present invention. In FIG. 3A, the locking signal in this embodiment is an encoding of “the indicator light of the Scroll Lock key is off, the indicator light of the Caps Lock key is on and the indicator light of the Num Lock key is on”, and the default action of this coding is to lock the Windows key of the keyboard device 11. Therefore, when the processing module 115 of the keyboard device 11 receives a signal encoded with “the indicator light of the Scroll Lock key is off, the indicator light of the Caps Lock key is on and the indicator light of the Num Lock key is on”, the decoding module 1151 decodes the signal received and obtains the action according to this signal to lock the Windows key of the keyboard device 11. Then, the keyboard controller 1153 locks the Windows key of the key module 111 according to the decoded result of the decoding module 1151 to make the Windows key not output signal to the computer 13 when being pressed.

In this embodiment, the unlocking signal is an encoding of “the indicator light of the Scroll Lock key is on, the indicator light of the Caps Lock key is off and the indicator light of the Num Lock key is on”, and the default action of this encoding is to unlock the Windows key of the keyboard device 11. Therefore, when the processing module 115 of the keyboard device 11 receives a signal encoded with “the indicator light of the Scroll Lock key is on, the indicator light of the Caps Lock key is off and the indicator light of the Num Lock key is on”, the decoding module 1151 decodes the signal received and obtains the action according to this signal to unlock the Windows key of the keyboard device 11. Then, the keyboard controller 1153 unlocks the Windows key of the key module 111 according to the decoded result of the decoding module 1151 to make the Windows key output signal to the computer 13 when pressed.

Referring to FIG. 3B, FIG. 3B is a schematic diagram of the signal code according to another embodiment of the present invention. The present embodiment is different from the embodiment in FIG. 3A in that the locking signal is an encoding of “the indicator light of the Scroll Lock key is off, the indicator light of the Caps Lock key is on/off three times per second and the indicator light of the Num Lock key is off”, and the default action of this coding is to lock the Caps Lock key of the keyboard device 11. Also, the unlocking signal is an encoding of “the indicator light of the Scroll Lock key is on/off three times per second, the indicator light of the Caps Lock key is off and the indicator light of the Num Lock key is off”, and the default action of this encoding is to unlock the Caps Lock key of the keyboard device 11.

The encodings of the locking signal and the unlocking signal shown in FIG. 3A and FIG. 3B are merely illustrative, to which the present invention is not limited. In practice, the locking signal and the unlocking signal could be encoded by any combination of the on/off of indicator lights of the Scroll Lock key, the Caps Lock key and the Num Lock key.

In one embodiment of the present invention, the peripheral device 15 is a mouse. The lock key 151 and the unlock key 153, for example, could be any possible combination of the left, right and/or scroll keys of a peripheral device 15. For example, pressing the left key and scrolling the scroll key up at the same time will output the locking signal, and pressing the left key and scrolling the scroll key down at the same time will output the unlocking signal, to which the present invention is not limited. The lock key 151 and the unlock key 153 also could be a specific key of the peripheral device 15, such as a separate key other than the left, right and scroll keys of mouse, to which the present invention is not limited.

In one embodiment of the present invention, the peripheral device 15 is a keyboard. The lock key 151 and the unlock key 153, for example, could be any possible combination of the keys of the keyboard, to which the present invention is not limited.

In one embodiment of the present invention, the transmission interface 117 and the transmission module 155, for example, could be the wireless transmission circuit of Bluetooth, WIFI, NFC, or ZigBee, and also could be the wired transmission circuit of USB or PS/2, to which the present invention is not limited.

In one embodiment of the present invention, the encoding module 157 includes an encoding table (not shown in the Figures). The encoding table could be implemented as a memory, a storage device or firmware, to which the present invention is not limited. The encoding table could store the coding information of the locking signal and the unlocking signal. The encoding module 157 generates the locking signal and the unlocking signal according to the encoding table.

In one embodiment of the present invention, the decoding module 1151 includes a decoding table (not shown in the Figures). The decoding table could be implemented as a memory, a storage device or firmware, to which the present invention is not limited. The decoding table could store the coding information of the locking signal and the unlocking signal. The decoding module 1151 decodes the locking signal and the unlocking signal according to the decoding table.

Referring to FIG. 4 and FIG. 2, FIG. 4 is a flowchart of a locking method for locking according to one embodiment of the present invention. In step S401, when the user wants to lock the specific key of the keyboard device 11 to avoid touching in the game play or software operation, the user can operate the lock key 151 of the peripheral device 15 to execute the action of locking. In step S403, the encoding module 157 of the peripheral device 15 generates a locking signal according to the keyboard indicator light control instruction outputted from the computer 13 to the keyboard device 11. The encoding module 157 wiredly or wirelessly transmits the locking signal to the computer 13 through the transmission module 155. The locking signal, for example, could be any combination of the on/off of indicator lights of the Scroll Lock key, the Caps Lock key and the Num Lock key.

In step S405, since the locking signal is encoded by the keyboard indicator light control instruction, the computer 13 can directly transmit the locking signal to the keyboard device 11 when receiving it from the peripheral device 15. In step S407, the processing module 115 of the keyboard device 11 wiredly or wirelessly receives the locking signal through the transmission interface 117, and then the decoding module 1151 decodes the locking signal. The keyboard controller 1153 locks the specific key of the key module 111 according to the decoded result of the decoding module 1151 to make the locked key stop outputting signal to the computer 13, thereby achieving the purpose of using a peripheral device 15 to lock the specific key of the keyboard device 11.

Referring to FIG. 5 and FIG. 2, FIG. 5 is a flowchart of a method for unlocking according to one embodiment of the present invention. In step S501, when the user wants to unlock the locked key of the keyboard device 11, the user can operate the unlock key 153 of the peripheral device 15 to execute the action of unlocking. In step S503, the encoding module 157 of the peripheral device 15 generates an unlocking signal according to the keyboard indicator light control instruction outputted from the computer 13 to the keyboard device 11. The encoding module 157 wiredly or wirelessly transmits the unlocking signal to the computer 13 through the transmission module 155. The unlocking signal, for example, could be any combination of the on/off of indicator lights of the Scroll Lock key, the Caps Lock key and the Num Lock key.

In step S505, since the unlocking signal is encoded by the keyboard indicator light control instruction, the computer 13 can directly transmit the unlocking signal to the keyboard device 11 when receiving it from the peripheral device 15. In step S507, the processing module 115 of the keyboard device 11 wiredly or wirelessly receives the unlocking signal through the transmission interface 117, and then the decoding module 1151 decodes the unlocking signal. The keyboard controller 1153 unlocks the locked key of the key module 111 according to the decoded result of the decoding module 1151 to make the locked key resume outputting signal to the computer 13, thereby achieving the purpose of using a peripheral device 15 to unlock the locked key of the keyboard device 11.
