Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] An embodiment of the present invention provides a method for setting a touch area, which is applied to a touch device. In this embodiment, a coordinate system is set based on the touch screen, with a vertex of the touch screen of the touch device as the coordinate origin, and two adjacent sides of the touch screen The straight lines are the x-axis and y-axis. Of course, this embodiment is just an example, and the center point of the touch screen can also be used as the coordinate origin, and two straight lines passing through the center point of the touch screen and parallel to the adjacent two sides of the touch screen can be used as the x-axis and the y-axis, as long as the coordinate system are unified, and how to set the coo...

Abstract

The invention discloses a touch area setting method and device, relates to the technical field of touch control, and solves the problem of a relatively large error between a position which a user wants to click in a display window and an actual response position when the size of the display window is changed in the prior art. According to the specific scheme, the method comprises the steps of obtaining physical coordinates of a first reference point; correcting the physical coordinates of the first reference point according to a first parameter so as to obtain physical coordinates of a second reference point corresponding to the first reference point on a touch screen; and setting a touch area according to the physical coordinates of the second reference point. The method and the device are used for setting the touch area.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a method and device for setting a touch area. Background technique [0002] The touch device can monitor the user's touch operation on the touch screen to realize human-computer interaction. Generally, the touch area of ​​the touch screen of the touch device and the display window of the display screen overlap each other. [0003] In the related art, the touch area of ​​the touch device and the size of the display window on the display screen have a 1:1 corresponding relationship, which can ensure the accuracy of the touch operation in the case of full-screen display. However, in some application scenarios, for example, a touch device displays an external computer connected to a high-definition multimedia interface (English: High Definition Multimedia Interface, HDMI), a video graphics array (English: Video Graphics Array, VGA) interface, etc. In these scenarios, the disp...
