Description
Technical Field
The present invention relates to an input system, a keyboard device and a locking method, and more particularly, to an input system, a keyboard device and a locking method for locking a specific key on a keyboard device.
Background
In the modern times, the use of computers has been an integral part of most people. Especially, when various types of software applications in different types such as electronic games, communities, and networks are developed, the faster the operating performance of the computer becomes.
For example, in the present computer game, it is often necessary to input the command quickly for the game operation. However, keys that are not required for a specific game, such as a control (Ctrl) key, an alternate (Alt) key, a Windows (Windows) key, a Shift (Shift) key, or a Caps lock (Caps lock) key, are often provided on a general computer keyboard device. If the user accidentally touches these keys which are not needed for the game while the game is in progress, the game may be interrupted or missed.
In the prior art, manufacturers have developed locking software that can be installed in a computer host. The user can operate the locking software to shield or lock the unnecessary specific keys on the keyboard device, so that the functions corresponding to the keys are not executed when the keys are pressed.
In the prior art, manufacturers also design specific keyboard devices, and the keyboard devices are provided with locking keys. The user can lock the specific key on the keyboard device by operating the locking keys.
However, by installing a locking software in the computer host to lock the keys of the keyboard device, the user needs to install the locking software, which increases the trouble of using the keyboard device. Meanwhile, installing locking software consumes certain computer host resources and may cause software conflicts.
When the keyboard device with the locking key is used for locking, a user needs to change the position of a hand to operate the locking key on the keyboard device during game playing or operation programs, and the game playing or operation programs are often interrupted. For example, when a user is playing a stimulating computer game, the left hand operates the game keys on the keyboard device and the right hand operates a mouse device to play the game. At this time, if the user needs to lock a specific key on the keyboard device, the original finger position must be changed to operate the lock key on the keyboard device. During the intense game, the action may generate the mistake of the game and even cause the interruption of the game.
Therefore, there is still much room for improvement in locking specific keys of a keyboard apparatus.

Since the unlocking signal is the code of the keyboard light control command, the host computer 13 can directly transmit the unlocking signal to the keyboard device 11 after receiving the unlocking signal output by the peripheral device 15.
Next, the processing module 115 of the keyboard apparatus 11 receives the unlocking signal through the transmission interface 117 in a wired or wireless manner, and the decoding module 1151 decodes the unlocking signal. The keyboard controller 1153 unlocks the specific key on the key module 111 according to the decoding result of the decoding module 1151, so that the originally locked key is restored to output the key signal to the host computer 13, thereby unlocking the locked key on the keyboard device 11.
The locking signal and the unlocking signal are coded according to a keyboard light signal control command which is output to the keyboard device 11 by the computer host 13. So that the host computer 13 can directly transmit the locking signal and the unlocking signal to the keyboard device 11 after receiving the locking signal and the unlocking signal output by the peripheral device 15. For details of the encoding, see the following example.
Referring to fig. 3A, fig. 3A is a schematic diagram of signal encoding according to an embodiment of the input system of the invention. As shown in the figure, the Lock signal in this embodiment is a code of "the light signal of the Scroll Lock (Scroll Lock) key is off, the light signal of the Caps Lock (Caps Lock) key is on, and the light signal of the number Lock (Num Lock) key is on" by default, and the code corresponds to a default action of locking the window (Windows) key of the keyboard apparatus 11. Therefore, after receiving a coded signal "the light signal of the Scroll Lock (Scroll Lock) key is turned off, the light signal of the Caps Lock (Caps Lock) key is turned on, and the light signal of the number Lock (Num Lock) key is turned on", the processing module 115 of the keyboard apparatus 11 decodes the coded signal, and knows that the corresponding action of the coded signal is to Lock the window (Windows) key of the keyboard apparatus 11. Then, the keyboard controller 1153 locks the window (Windows) key of the key module 111 according to the decoding result of the decoding module 1151, so that the key signal is not output to the host computer 13 when the window (Windows) key is pressed.

The codes of the locking signal and the unlocking signal shown in fig. 3A and 3B are only for illustration, and the present invention is not limited thereto. In practical applications, the expression of the Lock signal and unlock signal codes of the present invention may be any possible permutation and combination of the Scroll Lock (Scroll Lock) key, Caps Lock (Caps Lock) key, or number Lock (Num Lock) key of the keyboard device 11 indicating that the light signal is turned on/off.
In an embodiment of the present invention, the peripheral device 15 is a mouse. The lock key 151 and the unlock key 153 may be implemented by any possible combination of left, right, and/or wheel keys of the peripheral device 15. For example, pressing the left mouse button while dialing the roller key up outputs a lock signal, and pressing the left mouse button while dialing the roller key down outputs an unlock signal, which is not limited in the present invention. The lock key 151 and the unlock key 153 may be specific keys on the peripheral device 15, such as independent keys other than the left key, the right key and the wheel key of the mouse, but the invention is not limited thereto.
In one embodiment of the present invention, the peripheral device 15 is a keyboard. The lock key 151 and the unlock key 153 may be implemented by any possible combination of keys on the keypad, and the present invention is not limited thereto.
In one embodiment of the present invention, the peripheral device 15 has a control key (not shown), and the user can operate the control key to alternately output the locking signal and the unlocking signal. The user can output the locking signal after operating the control key once, and can output the unlocking signal after operating the control key once again.

The decoding module 1151 decodes the locking signal and the unlocking signal according to the decoding table.
Referring to fig. 4 and also to fig. 2, fig. 4 is a locking flowchart of a locking method of a keyboard apparatus according to an embodiment of the present invention. As shown in the figure, in step S401, when the user wants to lock a specific key on the keyboard device 11 to avoid mistaken touch for operating a game or a program. The user can operate the lock key 151 of the peripheral device 15 to perform a locking action with respect to the keyboard apparatus 11. Next, in step S403, the encoding module 157 of the peripheral device 15 encodes the key signal control command outputted by the host computer 13 to the keyboard device 11 to generate a locking signal. The encoding module 157 transmits the locking signal to the host computer 13 through the transmission module 155 in a wired or wireless manner. The expression of the Lock signal code may be any possible permutation and combination of the Scroll Lock (Scroll Lock) key, Caps Lock (Caps Lock) key, or number Lock (Num Lock) key of the keyboard apparatus 11 that indicates that the light signal is turned on/off.
Next, in step S405, since the Lock signal is a combination of on/off of the indicator light of the Scroll Lock (Scroll Lock) key, Caps Lock (Caps Lock) key or number Lock (Num Lock) key of the keyboard device 11, the host computer 13 can directly transmit the Lock signal to the keyboard device 11 after receiving the Lock signal output by the peripheral device 15. In step S407, after the processing module 115 of the keyboard apparatus 11 receives the lock signal through the transmission interface 117 in a wired or wireless manner, the decoding module 1151 decodes the lock signal. The keyboard controller 1153 locks the specific key on the key module 111 according to the decoding result of the decoding module 1151, so that the locked key stops outputting the key signal to the host computer 13, thereby achieving the purpose of locking the specific key on the keyboard device 11.

Next, in step S503, the encoding module 157 of the peripheral device 15 encodes the key signal control command outputted by the host computer 13 to the keyboard device 11 to generate an unlocking signal. The encoding module 157 transmits the unlocking signal to the host computer 13 through the transmission module 155 in a wired or wireless manner. The expression manner of the unlock signal code may be any possible permutation and combination of the turn-on/turn-off of the indicator light of the Scroll Lock (Scroll Lock) key, Caps Lock (Caps Lock) key, or number Lock (Num Lock) key of the keyboard apparatus 11.
Next, in step S505, since the unlocking signal is a combination of on/off of the indicator light of the Scroll Lock (Scroll Lock) key, Caps Lock (Caps Lock) key or number Lock (Num Lock) key of the keyboard device 11, the host computer 13 can directly transmit the unlocking signal to the keyboard device 11 after receiving the unlocking signal output by the peripheral device 15. In step S507, after the processing module 115 of the keyboard device 11 receives the unlocking signal through the transmission interface 117 in a wired or wireless manner, the decoding module 1151 decodes the unlocking signal. The keyboard controller 1153 unlocks the specific key on the key module 111 according to the decoding result of the decoding module 1151, so that the originally locked key can recover to output the key signal to the host computer 13 when being pressed, thereby unlocking the specific key locked on the keyboard device 11.
In summary, according to the technology of the disclosure, the input system provided by the present invention can generate the locking signal or the unlocking signal by encoding the keyboard light control command outputted from the host computer to the keyboard device. Therefore, the purpose of locking or unlocking the specific key on the keyboard device by using a peripheral device is achieved.
