In this embodiment, the touch sensing module 42 can include a plurality of electrode sensors 421 disposed under the keycaps 34 (as shown in FIG. 3). When the user's finger approaches the electrode sensor 421 disposed under the keycap 34, the electrode sensor 421 can generate a change in potential, thereby generating a corresponding one of the touch signals to the logic unit 40. In this way, the user can generate the touch signal by sliding the finger on the key cap 34, thereby touching the touch keyboard 3. In this embodiment, the logic unit 40 can be a processor unit.

Please refer to FIG. 4 , which is a flowchart of a method for inputting a touch command of the touch keyboard 3 according to an embodiment of the present invention. As shown in FIG. 4, the method for inputting the touch command includes the following steps: Step 100: The touch keyboard 3 is in a standby state; Step 102: sequentially touch a group of buttons 32 to cause the touch sensing module 42 to generate a phase Corresponding to the touch signal; Step 104: The logic unit 40 determines whether the touch signal meets a preset password value; if not, executes step 106; if yes, skips to step 108; Step 106: logic unit 40 performs a re-input The instruction returns to step 100; step 108: the logic unit 40 executes a touch command; and step 110: ends.

The above steps are described in detail herein. First, the touch keyboard 3 is coupled to a computer device to cause the touch keyboard 3 to communicate with the logic unit 40 to be in a standby state (step 100). Then, the user can sequentially touch a set of buttons 32 on the touch keyboard 3 in a sliding manner, so that the touch sensing module 42 generates the corresponding touch signal (step 102). Since each button 32 corresponds to a specific meaning, such as a letter, a number, etc., when the user sequentially touches a group of buttons 32 on the touch keyboard 3, the group of buttons 32 can form a specific path corresponding to a graphic. .

For example, as shown in FIG. 1, the button A, the button S, and the button D on the touch keyboard 3 are adjacent to each other. When the user sequentially touches the button A, the button S and the button D on the touch keyboard 3 in a sliding manner along the horizontal straight path on the touch keyboard 3, the touch sensing module 42 will respond accordingly. The touch signal of the horizontal straight path, that is, the touch signal is a straight line. At this time, the logic unit 40 can compare the touch signal corresponding to the straight line with a preset password value preset in the logic unit 40, and the logic unit 40 determines whether the touch signal corresponding to the horizontal straight path is consistent. The preset password value (step 104).

It should be noted that the horizontal straight path described above is only one of the embodiments (ie, a straight line) corresponding to the graphic, but the graphic formed by the specific path may not be limited to that described in this embodiment. For example, when the user sequentially touches the button A, the button Z, the button X, and the button S on the touch keyboard 3 in a sliding manner along the specific path on the touch keyboard 3, the specific path is formed. One of the graphics corresponds to a parallelogram. In summary, when the user sequentially touches a group of buttons 32 on the touch keyboard 3 in a sliding manner, as long as the user touches the group of buttons 32 along a specific path and the specific path can form a graphic. The above methods for inputting touch commands are all within the scope of protection of the present invention.

When the logic unit 40 determines that the touch signal corresponding to the horizontal straight path does not meet the preset password value, the logic unit 40 executes a re-input command, and the touch keyboard 3 returns to the standby state (step 100). In other words, when the logic unit 40 determines that the touch signal corresponding to the horizontal straight path does not meet the preset password value, the logic unit 40 executes the re-input command to enable the user to re-generate a touch using the touch keyboard 3. Control signal.

On the other hand, when the logic unit 40 determines that the touch signal corresponding to the horizontal straight path meets the preset password value, the logic unit 40 executes a touch command. In this embodiment, the touch command can be a screen unlock command. In other words, when the logic unit 40 determines that the touch signal corresponding to the horizontal straight path meets the preset password value, the logic unit 40 executes the screen unlocking command, so that the user can perform the desired execution by using the touch keyboard 3. Functions such as entering text, symbols or numbers.

In addition, the touch command may not be limited to that described in this embodiment. For example, the touch command can also be a reset preset password value command. In other words, when the logic unit 40 determines that the touch signal corresponding to the horizontal straight path meets the preset password value, the logic unit 40 executes the reset preset password value command, so that the user can re-use the touch keyboard 3 Set a default password value. As for which of the above designs is used, it depends on the actual design requirements.

In practice, when the user sequentially touches a group of buttons 32 on the touch keyboard 3, the group of buttons 32 can also form a specific path corresponding to one of the characters. For example, as shown in FIG. 1 , the buttons A, S, and D on the touch keyboard 3 are adjacent to each other, and the buttons Z, X, and C on the touch keyboard 3 are also in pairs with each other. Adjacent. When the user touches the touch keyboard 3 along a specific path, the first subgroup buttons (key A, button S, and button D) adjacent to each other on the touch keyboard 3 are sequentially touched in a sliding manner. And the second sub-group button (key Z, button X, and button C) adjacent to each other on the touch keyboard 3, the touch sensing module 42 generates the touch signal corresponding to the specific path. This means that the touch signal is a text "two."

At this time, the logic unit 40 can compare the touch signal corresponding to the text "2" with a preset password value preset in the logic unit 40, and the logic unit 40 determines the touch corresponding to the text "2". Whether the control signal complies with the preset password value. Then, the logic unit 40 performs the subsequent actions according to the determination result. Since the subsequent actions are the same as the above steps 106 and 108, the description is simplified for brevity.

It should be noted that the specific path described above is only one of the corresponding texts (ie, the text "two"), but the text formed by the specific path may not be limited to that described in this embodiment. For example, when the user touches the touch keyboard 3 along a specific path, the first subgroup buttons (key Q, button W) adjacent to each other on the touch keyboard 3 are sequentially touched in a sliding manner. And a button E), a second subgroup button (key A, button S and button D) adjacent to each other on the touch keyboard 3, and a third sub of the touch keyboard 3 adjacent to each other When the button is pressed (the button Z, the button X, and the button C), the touch sensor module 42 generates the touch signal corresponding to the specific path, that is, the touch signal is a text "three." In summary, when the user sequentially touches a group of buttons 32 on the touch keyboard 3, as long as the user touches the group of buttons 32 along a specific path and the specific path can form a character, the touch The method of controlling the command input is within the scope of protection of the present invention.

In addition, the user can also touch a button 32 only on the touch keyboard 3, and the button 32 corresponds to a symbol. For example, when the user touches the button A on the touch keyboard 3 on the touch keyboard 3, the touch sensing module 42 generates the touch signal corresponding to the touch action, that is, the touch The signal is a symbol A. At this time, the logic unit 40 can compare the touch signal corresponding to the symbol A with a preset password value preset in the logic unit 40, and the logic unit 40 determines whether the touch signal corresponding to the symbol A is consistent. The default password value. Then, the logic unit 40 performs the subsequent actions according to the determination result. Since the subsequent actions are the same as the above steps 106 and 108, the description is simplified for brevity.

It should be noted that the touch action described above is only one of the corresponding symbols (ie, symbol A), but the symbol corresponding to the touch action may not be limited to that described in this embodiment. For example, the user can also touch the button S on the touch keyboard 3, and one symbol corresponding to the touch action is a symbol S. In addition, the user can also touch the plurality of buttons 32 on the touch keyboard 3. In summary, as long as the user touches at least one of the buttons 32 on the touch keyboard 3 and the at least one button 32 can correspond to at least one symbol, the touch command input method belongs to the present invention.
