Embodiment 1

[0043] The embodiment of the present invention provides a method for realizing touch control, such as figure 1 As shown, the method includes:

[0044] 101. Obtain the first coordinates of N calibration points touched by the user; wherein, the first coordinates of the point refer to the pixel coordinates of the point on the display screen of the electronic device, and the pixel coordinates are determined by the distance from a specific pixel point on the display screen The pixel distance value constitutes; the first coordinates of at least 3 calibration points among the N calibration points are such that when the 3 calibration points are displayed on the display screen, they are not on the same straight line; N≥3, N is an integer.

[0045] The execution subject of the embodiment of the present invention may be an electronic device or a deepin device.

[0046] It should be noted that the depth device can detect changes in human body movements within its own viewing angle, and o...

Embodiment 2

[0072] The embodiment of the present invention further exemplifies the method for realizing touch control provided by the first embodiment. In this embodiment, N=3 is taken as an example for illustration, as follows image 3 As shown, the method includes:

[0073] 301. When the electronic device is started, the electronic device detects whether the mapping parameters need to be calibrated.

[0074] If yes, execute steps 302-307; if no, and the user touches the display screen of the electronic device, execute steps 305-307.

[0075] Specifically, when the electronic device detects that it does not store the mapping parameter K 0 、K 1 、K 2 、K 3 、K 4 and K 5 When , it is determined that the mapping parameters need to be calibrated; when the electronic device detects that it has stored the mapping parameters K 0 、K 1 、K 2 、K 3 、K 4 and K 5 When , it is determined that no calibration of the mapping parameters is required.

[0076] It should be noted that for relevant e...

Embodiment 3

[0091] The embodiment of the present invention provides a device 40 for realizing touch control, which is used to realize figure 1 As shown in the method of implementing touch, such as Figure 4 As shown, the device 40 includes:

[0092] The first acquisition unit 401 is configured to acquire the first coordinates of the N calibration points touched by the user; wherein, the first coordinates of the point refer to the pixel coordinates of the point on the display screen of the electronic device, and the pixel coordinates are displayed by distance The pixel distance value of a specific pixel on the screen constitutes; the first coordinates of at least 3 calibration points in the N calibration points make the 3 calibration points not on the same straight line when they are displayed on the display screen; N≥3, N is integer.

[0093] The second acquiring unit 402 is configured to acquire the second coordinates of the N calibration points displayed on the display screen sequenti...

Abstract

A touch implementation method and device and an electronic device are provided, and the method includes: displaying N calibration points for user touch by a display screen of an electronic device; acquiring first coordinates of the N calibration points for user touch; acquiring second coordinates of the N calibration points; and calculating a mapping parameter between a first coordinate of a point and a second coordinate of the point according to the first coordinates of the N calibration points and the second coordinates of the N calibration points. The mapping parameter is configured for acquiring a first coordinate of a touch point touched by the user upon a user touching the display screen. Embodiments of present disclosure can reduce the cost of the electronic.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method and device for realizing touch control. Background technique [0002] At present, many electronic devices (for example, mobile phones or tablet computers, etc.) have touch functions, that is, users can operate electronic devices by touching the display screen. Common touchable display screens include capacitive touch screens and resistive touch screens, etc. . [0003] Capacitive touch screens or resistive touch screens are generally set on electronic devices, and are consistent with the size of the display screen of the electronic device, so that each electronic device needs to be equipped with a touch screen that is consistent with the size of its own display screen, and each new size All touch screens need to be re-developed, increasing the cost of electronic equipment. Contents of the invention [0004] Embodiments of the present invention provide a m...
