Bits 1016~1026. In this embodiment, the user can select the desired keyboard layout for editing operation by clicking one of the keyboard layout options 1004~1014. The start condition field 1016~1026 is used to describe the possible application scenarios of the keyboard layout options 1004~1014 corresponding to the trigger start. For example, the user can understand from the description text "computer, small abacus" in the start condition field 1022 that the keyboard layout option 1010 is preset to correspond to the execution of "computer" or "small abacus" applications. The keyboard layout that triggers the launch (such as the keyboard layout in Figure 7A).

On the other hand, when the user clicks the keyboard layout option 1010, the content of the start condition field corresponding to the addition and deletion can be edited; for example, deleting the "computer" and adding the "Sudoku game" program, so that when the user executes "Sudoku" In the game mode, the touch display and operation body 108 will display the keyboard layout as shown in FIG. 7A as the current keyboard layout. However, the present invention is not limited to the above-described examples, and it is within the spirit of the present invention to display the form for the user to select the desired keyboard layout.

Please refer to FIG. 11A, which illustrates the touch display of the embodiment of the present invention. A schematic diagram of the operating body 108 is shown. As shown in FIG. 11A , the touch display and operation body 108 includes a display layer 1102 , a capacitive sensing layer 1104 , and a switch layer 1106 . Display layer 1102 is used to dynamically display the current keyboard layout. The capacitive sensing layer 1104 is disposed under the liquid crystal display layer 1102 for sensing a touch operation to generate a corresponding touch signal. The switch layer 1106 is disposed under the liquid crystal display layer 1102 and has a plurality of switches thereon, and the individual switches are responsive to the pressing operation to independently generate corresponding button signals. The control unit 106 communicates with the system end 102 according to the touch signal and the button signal.

The display layer 1102 is, for example, an organic light emitting diode (OLED) layer, which can dynamically display the position and size of each button in the current keyboard layout according to the control signal sent by the control unit 106, thus prompting the user to operate. The position of the switch on the corresponding switch layer 1106 can be correctly pressed. The capacitive sensing layer 1104 can generate a corresponding change in capacitance value in response to a touch operation (such as a touch operation gesture of the user), and thereby generate a touch signal. The individual switches on the switch layer 1106 can be independently turned on in response to the pressing operation to generate a button signal corresponding to the button.

In one embodiment, the touch display and operation body 108 further has a key cap layer 1108 disposed under the display layer 1102. The keycap layer 1108 has at least one protrusion unit 1110 that can be pressed. Since the protrusion unit 1110 has resilience in response to the pressing operation, the user can have the feel of tapping the keyboard button when making a key input on the touch display and the operating body 108. Please refer to FIG. 11B. In an example, the configuration of the protrusion unit 1110 on the cap layer 1108 preferably corresponds to the standard. The quasi-keyboard layout, and the size of the button area and the corresponding pattern displayed by the display layer 1102 are determined by the control unit 106. For example, the area of the button pattern displayed by the display layer 1102 may include only a single protrusion unit 1110, and may also include a plurality of protrusion units 1110. The area of the button pattern is substantially adjusted by an integral multiple of the protrusion unit 1110. For example, in FIG. 11B, the display layer 1102 displays only the digital pattern of the numeric keypad (indicated by a thick frame in the figure), wherein the number corresponding to the numeric key "1" to the numeric key "9" and the symbol "." The pattern size includes two protrusion units 1110, and the digital pattern corresponding to the number key "0" includes four protrusion units 1110.

Please refer to FIG. 12, which is a flowchart of a method for operating the peripheral device 100 according to an embodiment of the present invention. This method of operation has the following steps: First, in step S1, the peripheral device 104 receives system status information from the system terminal 102. Next, in step S2, the control unit 106 of the peripheral device 104 determines, according to the system status information, whether a plurality of preset keyboard layouts stored in the keyboard layout summary table 1002 can be selected as the current keyboard layout. If yes, in step S3, the current keyboard layout corresponding to the keyboard layout summary table 1002 is displayed on the touch display and operation body 108. If not, the control unit 106 determines whether the number of touch points on the touch display and operation body 108 is greater than a critical value and there is no continuous movement gesture. If yes, step S5 is executed, and the control unit 106 causes the peripheral device 104 to enter the keyboard mode. If no, step S6 is executed, and the control unit 106 causes the peripheral device 104 to enter the mouse mode.

According to the above, the control unit 106 of the peripheral device 104 changes to the touch display when the current keyboard layout cannot be selected according to the system status information. The form of the number of touch points on the operating body 108 and the form of the track are determined to enter the keyboard mode (corresponding to keyboard operation) or the mouse mode (corresponding to the mouse operation). Therefore, the applicant has found that when the user performs a keyboard operation (for example, typing), a plurality of fingers are usually placed on the touch display and operation body 108 at the same time (for example, to generate more than three touch points). And the touch trajectory generated along with the keyboard operation is point-like. Conversely, when the user performs a mouse operation in a touch manner (for example, dragging a file or zooming a pattern size), only a few fingers operate on the touch display and operation body 108 (for example, generating less than three Touch points), and the touch track generated by the mouse operation is a continuous moving gesture. Therefore, it can be effectively determined by determining whether the number of touch points generated on the touch display and the operating body 108 is greater than a threshold value (for example, three touch points) and whether the touch track is continuous. Determine if the user wants to take a keyboard operation or a mouse operation.
