Problems solved by technology

It can be seen that the viewing angle of the user viewing the screen will increase with the increase of the screen size, thereby increasing the parallax of the user viewing the objects under the screen, resulting in a large gap between the touch position of the finger and the display position of the object , resulting in erroneous operation of the electronic device

Embodiment Construction

[0019] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0020] The present invention combines position sensors such as an image sensor and a proximity sensor configured on an electronic device to detect the relative position between the user's eyes and the screen display objects when viewing the screen, and then calculates The parallax of the object viewed by the user is displayed, and the deviation of the touch position caused by the parallax is compensated. Through the above touch position compensation, the present invention can more accurately identify the object that the user intends to operate and the user's action of operating the object.

[0021] figure 2 It is a schematic diagram of a finger touching an object displayed on the screen according to an embodiment of the present invention. Please refer to f...

Abstract

The invention relates to a compensation method and device for touch positions. The compensation method and device are suitable for an electronic device with a touch screen and a plurality of position sensors. According to the method, the position sensors detect the positions of the eyes, relative to the touch screen, of a user and obtain the positions of objects displayed by the touch screen, the visual angles of watching the objects by the eyes are calculated according to the positions of the eyes and the positions of the objects, and the parallax errors of watching the objects by the eyes are calculated according to the visual angles and the thickness of the touch screen. The parallax errors are used for compensating the touch positions of the objects displayed by touching the touch screen through the fingers of the user. According to the method and device, the visual angles of watching the objects by the user are calculated by detecting the positions of the eyes, relative to the objects displayed on the touch screen, of the user, the detected touch positions by the touch screen are adjusted so that the positional deviation, caused by the parallax errors, of the touch positions can be compensated. In addition, the accuracy degree of compensation of the touch positions can be improved due to three-dimensional space detection of the touch screen and finger size detection of the user.

Description

technical field [0001] The invention relates to a method and device for detecting a touch position, and in particular to a method and a device for detecting an eye position to compensate for a touch position. Background technique [0002] Compared with the traditional keyboard input method, the operation method of the touch screen has simple and intuitive advantages. Therefore, today's consumer electronics products such as mobile phones, personal digital assistants, tablet computers, and even notebook computers, desktop computers and various household appliances, There is a trend of using a touch screen instead of a traditional keyboard as an input interface. [0003] In the traditional keyboard input method, the user must press the keyboard while comparing the images displayed on the screen to successfully complete the operation functions such as text input or menu switching. However, if the touch screen operation method is adopted, the user can easily operate various func...
