Abstract

The invention relates to the technical field of touch screens. A self-adaption virtual keyboard system comprises a micro-processor system, a touch position detection module and a display device, wherein a display frame of the display device comprises a keyboard frame containing English letters from A to Z of a standard keyboard; the micro-processor system is used for executing a keyboard adjustment program; when executing the keyboard adjustment program, the micro-processor system is used for promoting a user to input letters of at least three different positions; at least three pieces of coordinate information of at least three different touch points are respectively determined by the micro-processor system through the touch position detection module; when the coordinate information at the three touch positions does not completely coincide with coordinates of the three letters, the display device is controlled by the micro-processor system to adjust the size of the keyboard frame. As the technical scheme is adopted, the self-adaption virtual keyboard system is capable of automatically adjusting the keyboard frame according to different users, and has a keyboard self-adaption function.

Description

technical field [0001] The invention relates to the field of computers, in particular to the field of touch screens. Background technique [0002] Touch screens are now being used on more and more devices. The touch screen is a convenient and intuitive input device. However, the existing touch screen faces the problems of large volume, inconvenient installation, poor anti-interference ability and easy damage. These problems limit the freedom of the operator in selecting the functions of the touch screen, and limit the use environment of the touch screen. [0003] With the development of optoelectronic technology, the ability of electronic equipment to identify and locate related images is getting stronger and stronger. For example, the existing image positioning system on the laser virtual keyboard has high recognition and positioning capabilities, and can obtain the click position of the operator more accurately; Identify and locate. However, the existing image interac...
