[0019] Hereinafter, the technical means in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings. It is clear that the described embodiments are not all embodiments but only a part of the embodiments of the present invention. Furthermore, it should be understood that the specific embodiments described in this specification are only used for the explanation and interpretation of the present invention and are not used to limit the present invention. Referring to the accompanying drawings, the same element symbols indicate the same elements.

[0020] 1 is a block diagram illustrating a touch device according to an embodiment of the present invention. The touch device 1 according to the present invention includes: a capacitive button 10; a touch screen 20 having a button body arrangement portion A1 on which the capacitive button 10 is disposed and a touch portion A2 located outside the button body arrangement portion A1; a sensor device 30 connected to the touch screen 20 and the capacitive button 10 and configured to sense first data from the button body arrangement portion A1 and second data from the touch portion A2 in real time; a calculation unit 40 connected to the sensor device 30 and the touch screen 20 and configured to calculate, based on the first data, the second data, and an output signal from the touch screen 20, a parameter adjustment amount for balancing the signal-to-noise ratio of the output signal from the button body arrangement portion A1 and the signal-to-noise ratio of the output signal from the touch portion A2; and a balance unit 50 connected to the calculation unit 40 and the touch screen 20 and configured to adjust the touch screen 20 according to the parameter adjustment amount.

[0021] The sensor device 30 may be a charge sensor for measuring or calculating a corresponding material charge when the material is subjected to stress and deformed.

[0022] The capacitive button 10 according to the present invention is directly attached to a touchscreen 20 having a conventional touch function, and the placement of the capacitive button 10 changes the surface charge of the button body placement portion A1 of the touchscreen 20. Therefore, the present invention simplifies the measurement of the corresponding signal-to-noise ratio by measuring data on the button body placement portion A1 and the touch portion A2 using a sensor device 30 directly connected to the touchscreen 20 and the capacitive button 10, and directly calculating parameter adjustment amounts for balancing the touchscreen 20, the button body placement portion A1, and the touch portion A2 based on the first data, the second data, and the output signal of the touchscreen 20 using a calculation unit 40. Therefore, the present invention can directly and accurately balance the signal-to-noise ratios of the output signals of the button body placement portion A1 and the touch portion A2 without additionally measuring the output signal strength and noise intensity of the button body placement portion A1 and the touch portion A2 in real time using the capacitive button 10, the touchscreen 20, and the sensor device 30. The first data may include capacitance data and / or charge data of the button body arrangement portion A1, and the second data may include capacitance data and / or charge data of the touch portion A2.

[0023] 2, which illustrates the distribution of button body arrangement portions and touch portions in a touch screen according to an embodiment of the present invention. In the touch screen 20, a button body arrangement portion A1 is arranged at the bottom of the touch screen 20. For a large touch screen 20, a user who needs physical buttons to assist in using the touch screen 20 approaches the touch screen 20 and presses a capacitive button 10 provided on the button body arrangement portion A1 to generate an input signal on the touch screen 20.

[0024] 3, which illustrates the distribution of button body arrangement portions and touch portions in a touch screen according to another embodiment of the present invention. In the touch screen 20, a button body arrangement portion A1 is arranged on one side of the touch screen 20. A user presses a capacitive button 10 provided on the button body arrangement portion A1 at the edge of the touch screen 20 to generate an input signal on the touch screen 20.

[0025] Next, a block diagram of the capacitive button 10 of the present invention will be further described. Referring to FIG. 4, the capacitive button 10 includes a contact portion 11 and an elastic portion 12. When the capacitive button 10 is pressed, the contact portion 11 is electrically connected to the touch screen 20. The elastic portion 12 is made of a conductive material, such as conductive rubber. When the capacitive button 10 is mounted on the touch screen 20, the interior of the elastic portion 12 provides a space sufficient to accommodate the contact portion 11. The contact portion 11 is connected to the elastic portion 12 and is located at the lower edge of the elastic portion 12. Therefore, electromagnetic interference signals transmitted from outside the capacitive button 10 can be directly blocked by the elastic portion 12 without affecting the contact portion 11 therein. It should be further noted that the elastic portion 12 is directly connected to the pressing mechanism of the capacitive button 10. Therefore, when a user presses the capacitive button 10, the elastic portion 12 is also compressed accordingly.

[0026] Next, the present invention further provides another embodiment of the capacitive button 10. Referring to Fig. 5, the capacitive button 10 includes a contact portion 11, an elastic portion 12, and a touch capacitive sheet 13. The touch capacitive sheet 13 is provided on a touch screen 20, and when the capacitive button 10 is pressed, the contact portion 11 is electrically connected to the touch capacitive sheet 13. The provision of the touch capacitive sheet 13 amplifies the signal output from the capacitive button 10 to the touch screen 20, thereby reducing the volume and bottom contact area of ​​the contact portion 11 and ensuring signal transmission of the touch device.

[0027] In another embodiment of the present invention, the elastic portion 12 is further connected to the touch screen 20 and is made of a conductive material. The elastic portion charge of the elastic portion 12 changes according to the deformation of the elastic portion. The first data sensed by the sensor device 30 according to the present invention further includes elastic portion charge state data representing the change in the charge of the elastic portion 12. The calculation unit 40 is further configured to calculate a parameter adjustment amount based on the first data including the elastic portion charge state data, thereby enabling the present invention to adjust the operating parameters of the touch screen 20 in real time using the balancing unit 50 according to the pressing state of the capacitive button 10.

[0028] In another embodiment of the present invention, the calculation unit 40 is further configured to calculate a signal output threshold based on the first data, and the calculation unit 40 is further configured to determine whether the output signal generated by the button body arrangement portion A1 is greater than the signal output threshold. If the output signal is greater than the signal output threshold, the balance unit 50 controls the touch screen 20 to receive the output signal. In this way, the present invention can further identify whether the capacitive button 10 is pressed. After identifying that the capacitive button 10 is pressed, the touch screen 20 receives the output signal transmitted from the button body arrangement portion A1.

[0029] Please continue to refer to FIGS. 6 to 8, which respectively disclose different embodiments of the control method for a touch device according to the present invention.

[0030] First, refer to Fig. 6. The control method for a touch device according to the present invention includes steps S1 to S4.

[0031] S1: A touch screen provided with a capacitive button is used. The touch screen has a button body arrangement portion where the capacitive button is arranged and a touch portion located outside the button body arrangement portion.

[0032] Therefore, in order to improve the operational effect of the touch device of the combined physical button and touch screen of the present invention, the touch screen 20 is divided into a button body arrangement area A1 where the capacitive button 10 is arranged and a touch area A2 located other than the button body arrangement area A1.

[0033] S2: Using the sensor device, the first data of the button body arrangement portion and the second data of the touch portion are sensed in real time.

[0034] This allows the first data of the button body arrangement portion A1 and the second data of the touch portion A2 to be sensed in real time, thereby evaluating the amount of change in the pressure state of the capacitive button 10 in the button body arrangement portion A1 in real time in order to improve the accuracy of the output signals of the button body arrangement portion A1 and the touch portion A2 of the present invention.

[0035] S3: Using the calculation unit, calculate a parameter adjustment amount that balances the signal-to-noise ratio of the output signal of the button body arrangement part and the signal-to-noise ratio of the output signal of the touch part based on the first data, the second data, and the output signal of the touch screen.

[0036] By comparing the first data, the second data, and the output signal of the touch screen, the present invention allows the calculation unit 40 to obtain in real time a parameter adjustment amount that balances the signal-to-noise ratio of the output signal of the button body arrangement part A1 and the signal-to-noise ratio of the output signal of the touch part A2, so as to simplify the calculation resources required by the touch device 1.

[0037] S4: Using the balance unit, adjust the touch screen based on the parameter adjustment amount.

[0038] The balancing unit 50 directly implements the parameter adjustment amount obtained by the calculation unit 40, and improves the accuracy of the output signals of the button body arrangement part A1 and the touch part A2, so that the present invention can balance the signal-to-noise ratio of the button body arrangement part A1 and the touch part A2 in the touch device 1 in real time.

[0039] In another embodiment of the present invention, the method for controlling the touch device further includes pressing the capacitive button 10 to establish electrical continuity between the contact portion 11 of the capacitive button 10 and the touch screen 20. This allows the touch device 1 of the present invention to simultaneously provide two operation methods: touch operation and button pressing operation.

[0040] In another embodiment of the present invention, the control method for the touch device further includes pressing the capacitive button 10 to compress the elastic part 12, thereby electrically connecting the contact part 11 located at the lower edge of the elastic part 12 with the touch screen 20. In this way, the touch device 1 of the present invention can simultaneously provide two operation methods, namely, a touch operation and a button pressing operation, and simultaneously provide elastic pressing feedback to the button body arrangement part A1.

[0041] 7, which is a flow chart illustrating a method for controlling a touch device according to another embodiment of the present invention, the method for controlling a touch device further includes steps S21 to S22.

[0042] S21: Using a sensor device, first data including elastic portion charge state data that changes with the amount of deformation of the elastic portion is sensed.

[0043] S22: Using the calculation unit, calculate the parameter adjustment amount based on the first data including the elastic portion charge state data.

[0044] Since the first data sensed by the sensor device 30 includes the change in charge caused by the deformation of the elastic part 12 under force, the present invention can further enable the calculation unit 40 to more accurately balance the signal adjustment amount of the output signals from the button body arrangement part A1 and the touch part A2 based on the pressing state of the elastic part 12. Therefore, compared with simply adding a button, the capacitive button 10 provided on the button body arrangement part A1 of the touch device 1 according to the present invention can further output different signals according to different pressing states.

[0045] Continuing to refer to Fig. 8, which is a flow chart illustrating a method for controlling a touch device according to another embodiment of the present invention, the method for controlling a touch device further includes steps S31 to S32.

[0046] S31: Using a calculation unit, calculate a signal output threshold value based on the first data.

[0047] S32: Using the calculation unit, determine whether the output signal generated by the button body arrangement part is greater than the signal output threshold.

[0048] Here, if the output signal is greater than the signal output threshold, the touch screen is used to receive the output signal.

[0049] As a result, when the capacitive button 10 provided on the button body arrangement part A1 of the touch device 1 according to the present invention is lightly pressed, but the pressing state does not satisfy the pressing threshold value that matches the conductivity data, the signal output by the capacitive button 10 provided on the button body arrangement part A1 is not received by the touch screen 20. Therefore, interference with the operation of the touch device 1 caused by an erroneous signal output due to a light pressing of the capacitive button 10 provided on the button body arrangement part A1 is further avoided.

[0050] Furthermore, the button structure of the touch device 1 of the present invention allows the capacitive button 10 to be directly placed at any position on the touch screen 20, and the operating parameters of the touch screen 20 can be balanced by the sensor device 30, the calculation unit 40, and the balancing unit 50. Therefore, the application scenarios for adding buttons are not limited by the mold and matching circuitry that are used for adding buttons to conventional panels. For example, the touch device 1 of the present invention can be installed in different application scenarios, such as advertising panels, driving dashboards, tablet computers, washing machines, and automated teller machine panels.

[0051] The present invention provides a touch device and a control method thereof, which have at least the following beneficial effects: a capacitive button 10 is provided above a touch screen 20, and a sensor device 30 senses the conductivity data of the button body area A1 and the touch area A2 in real time, allowing a calculation unit 40 and a balancing unit 50 to balance the signal-to-noise ratios of output signals from different areas of the touch device 1. This allows the button elements to provide physical feedback to the touch screen 20 using a simplified system design, without restricting the original function of the touch screen 20. At the same time, this allows a touch device with additional panel buttons to have a faster response speed, and does not limit the use scenarios of the touch device.

[0052] It should be noted that the combination of various elements in the present invention preferably forms the above-mentioned multiple embodiments, but should not be construed as a limitation on the present invention, that is, the various elements in the present invention are not limited to the above-mentioned multiple embodiments, and can have many more combination methods.

As will be understood by those skilled in the art, they may still modify the technical means described in the above embodiments or replace part of the technical means with equivalents, but these modifications or replacements should be understood to be within the scope of the technical means of the embodiments of the present invention without departing from the essence of the corresponding technical means.
