Abstract

An electronic device with virtual touch service and a virtual touch real-time calibration method. The virtual touch real-time correction method includes the following steps. The image of at least one user is captured by the image capture device. The distance between the image capture device and the user is sensed. The position and range of the touch sensing plane area are defined according to the distance. Corresponding the touch sensing plane area to the effective display area of ​​the display screen. And, displaying a display image mapped to the image on the display screen for the user to touch the relative position of the touch-sensing plane area corresponding to the display screen according to the display image, wherein the size of the display image does not matter whether the distance changes constant.

Description

[0001] 【Technical field】 [0002] The present invention relates to a virtual touch method, in particular to an electronic device with virtual touch service and a virtual touch real-time calibration method. [0003] 【Background technique】 [0004] Compared with the prior art, the user needs to control the electronic device through an input interface, such as a mouse, a keyboard, and a key set. Today's electronic devices, such as PDAs, mobile phones, digital photo frames, and digital panels, are equipped with The touch screen is convenient for the user to achieve the function of inputting data by touching the screen, and does not need to use an additional physical input device. [0005] As touch screens become mainstream, computer designers are starting to develop a new generation of technology, allowing users to operate electronic devices such as TVs and computers in the air by simply moving their limbs or fingers without touching them with their fingers or using a remote contro...
