Abstract

Disclosed is a touch control method for a display. The method includes: after a reflection signal is received by means of a receiving component of a laser sensor, generating an image according to a laser signal and the reflection signal; acquiring gesture information of a user according to the image; and executing a control operation corresponding to the gesture information. Further disclosed are a terminal device and a computer-readable storage medium.

First claim

What is claimed is:

1. A touch control method for a display, wherein the display is provided with a laser sensor, the laser sensor comprises a scanning component and a receiving component, the scanning component is used to emit laser signal, the receiving component is used to receive reflection signal, a plane on which the laser signal is located is parallel to a display screen of the display, the touch control method for the display comprises: after the reflection signal is received by means of the receiving component of the laser sensor, generating an image according to the laser signal and the reflection signal; acquiring gesture information of a user according to the image; and executing a control operation corresponding to the gesture information;
wherein the acquiring of the gesture information of the user according to the image comprises:
acquiring coordinate information of each pixel in the image;
deleting pixels with coordinate information beyond a preset area in the image to obtain an updated image; and
acquiring the gesture information of the user according to the updated image; and

wherein the touch control method for the display further comprises:
acquiring size information of the display screen;
acquiring a center position of the laser sensor, and acquiring a distance from the center position of the laser sensor to a center position of the display screen; and
determining a coordinate range of the preset area according to the center position of the laser sensor, the distance, and the size information of the display screen.

2. The touch control method for the display as claimed in claim 1 , wherein the touch control method for the display further comprises:
acquiring an area of the preset area according to the coordinate range;
acquiring an area of the display screen according to the size information of the display screen; and
when the area of the preset area is larger than the area of the display screen, outputting a prompt message that the preset area is set incorrectly.

3. The touch control method for the display as claimed in claim 1 , wherein the executing of the control operation corresponding to the gesture information comprises:
acquiring position information and motion information corresponding to a currently displayed interface on the display according to the gesture information; and
executing a corresponding control operation according to the position information and the motion information.

4. The touch control method for the display as claimed in claim 1 , wherein the touch control method for the display further comprises:
converting the gesture information into a mouse mapping event corresponding to a display interface of the display.

5. The touch control method for the display as claimed in claim 4 , wherein the mouse mapping event comprises one of single-click, double-click, drag, and selection.

6. A terminal device, wherein the terminal device comprises a display, a processor, a memory, and a touch control program of the display that is stored in the memory and is executable by the processor to perform the touch control method for the display as claimed in claim 1 .

7. A non-transitory computer-readable storage medium, wherein a touch control program of a display is stored on the computer-readable storage medium and is executable by a processor to perform the touch control method for the display as claimed in claim 1 .

8. A touch control method for a display, wherein the display is provided with a laser sensor, the laser sensor comprises a scanning component and a receiving component, the scanning component is used to emit laser signal, the receiving component is used to receive reflection signal, a plane on which the laser signal is located is parallel to a display screen of the display, the touch control method for the display comprises: after the reflection signal is received by means of the receiving component of the laser sensor, generating an image according to the laser signal and the reflection signal; acquiring gesture information of a user according to the image; and executing a control operation corresponding to the gesture information;
wherein the acquiring of the gesture information of the user according to the image comprises:
acquiring coordinate information of each pixel in the image;
deleting pixels with coordinate information beyond a preset area in the image to obtain an updated image; and
acquiring the gesture information of the user according to the updated image; and

wherein the touch control method for the display further comprises:
detecting coordinates of a plurality of preset positions of the display by means of the laser sensor; and
determining a coordinate range of the preset area according to the coordinates of the plurality of preset positions and a center position of the laser sensor.

9. The touch control method for the display as claimed in claim 8 , wherein the executing of the control operation corresponding to the gesture information comprises:
acquiring position information and motion information corresponding to a currently displayed interface on the display according to the gesture information; and
executing a corresponding control operation according to the position information and the motion information.

10. The touch control method for the display as claimed in claim 8 , wherein the touch control method for the display further comprises:
converting the gesture information into a mouse mapping event corresponding to a display interface of the display.

11. The touch control method for the display as claimed in claim 10 , wherein the mouse mapping event comprises one of single-click, double-click, drag, and selection.

12. A terminal device, wherein the terminal device comprises a display, a processor, a memory, and a touch control program of the display that is stored in the memory and is executable by the processor to perform the touch control method for the display as claimed in claim 8 .

13. A non-transitory computer-readable storage medium, wherein a touch control program of a display is stored on the computer-readable storage medium and is executable by a processor to perform the touch control method for the display as claimed in claim 8 .

14. A touch control method for a display, wherein the display is provided with a laser sensor, the laser sensor comprises a scanning component and a receiving component, the scanning component is used to emit laser signal, the receiving component is used to receive reflection signal, a plane on which the laser signal is located is parallel to a display screen of the display, the touch control method for the display comprises: after the reflection signal is received by means of the receiving component of the laser sensor, generating an image according to the laser signal and the reflection signal; acquiring gesture information of a user according to the image; and executing a control operation corresponding to the gesture information;
wherein the acquiring of the gesture information of the user according to the image comprises:
acquiring coordinate information of each pixel in the image;
deleting pixels with coordinate information beyond a preset area in the image to obtain an updated image; and
acquiring the gesture information of the user according to the updated image; and

wherein the touch control method for the display further comprises:
performing grid processing on the preset area, so that a size of a grid is same as a size of the pixel of the display screen, and converting grids in the preset area into pixels.

15. The touch control method for the display as claimed in
