Abstract

Provided are an electronic device with virtual touch service and a virtual touch immediate correction method. The virtual touch immediate correction method includes the following steps: utilizing an image acquisition device to acquire an image of at least one user, sensing the distance between the image acquisition device and the user, defining the position and the range of a touch sensing area according to the distance, enabling the touch sensing area to correspond to an effective display area of a display screen and displaying a display image mapped with the image on the display screen to enable the user to touch relative positions of the touch sensing area corresponding to the display screen according to the displayed image. The size of the displayed image is not changed whether the distance is changed or not.

Description

【Technical field】 [0001] 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. 【Background technique】 [0002] 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. [0003] 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 control. [0004] Sp...
