Problems solved by technology

First of all, because the user's operating space is completely limited within the plane range of the touch screen, if the area of ​​the touch screen is too small, it will bring great inconvenience to the user when using the touch screen.
Conversely, if the area of ​​the touch screen is too large, the volume of the electronic device on which the touch screen is installed will inevitably become larger, which has a great impact on portable devices such as mobile phones.
The second is the cost issue. The cost of the touch screen is higher than that of the traditional TFT (Thin Film Transistor, thin film transistor) screen.
In addition, the touch operation may dirty the screen of the electronic device

Abstract

The invention provides a method for implementing non-contact interface control, which is applied in an electronic device. The method comprises the following steps: prompting a user to select an object, placing an image of the object in a predetermined position on a screen of the electronic device, and calculating and storing RGB value and area of the image of the object; tracking the motion trackof the object according to the RGB value, and displaying the motion track on the screen of the electronic device; and comparing the current image area of the object with the stored image area, and ifthe ratio of the current image area to the stored image area exceeds the predetermined ratio, executing an interface control operation. The invention also provides the electronic device for implementing the non-contact interface control. A touch screen does not need to be installed, and the interface control of the electronic device can be realized in a non-contact mode.

Description

technical field [0001] The invention relates to an interface control technology, in particular to a method and an electronic device for realizing non-contact interface control. Background technique [0002] As an input device of an electronic device, a touch screen can realize simple, convenient and natural interface control. The touch screen is mainly used to replace the work of the mouse or keyboard. When using a touch screen for interface control operations, the user first needs to touch the touch screen installed on the front of the display with a finger or other objects, and then the touch screen locates the input of selection information according to the position of the icon or menu touched by the finger. [0003] The touch screen consists of two parts: a touch detection device and a touch screen controller. The touch detection device is installed at the front end of the display screen for detecting the user's contact position. The main function of the touch screen ...
