A contactless control device for a mobile terminal

Abstract

The invention provides a non-contact control device for a mobile terminal, which includes a protective film for the mobile terminal, a camera, a sensor and a main controller; the camera is used to collect face and / or eye information, After taking the image, the image is sent to the main controller; there are several preset positioning points on the protective film of the mobile terminal; the main controller controls the The operation icon on the screen interface of the mobile terminal moves to realize the interaction with the mobile terminal; the sensor controls the operation icon on the screen interface of the mobile terminal to move according to the change of the positional relationship between the collected signal and the positioning point, so as to realize the interaction with the mobile terminal. terminal interaction. The invention can realize non-contact interactive control with the mobile terminal.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a non-contact control device for a mobile terminal. Background technique [0002] In the prior art, interactive touch is realized by a real finger or a stylus. Its disadvantage is that people have to actually move and click with their fingers, and at the same time, the current general mobile phone film needs to be conductive in order to be sensed by the touch screen. In order to achieve interaction, the fingers need to be long and tiring, the screen should be small, the electrical parameters of the touch screen should be sensitive, and the mobile phone film is not insulated, which restricts the development and use of mobile phones and brings unsafe factors to people. Because the screen of the mobile phone is getting bigger and bigger, after being compatible with the functions of the computer, it is increasingly replacing the tablet. The mobile phone is a tablet computer...

Problems solved by technology

Its disadvantage is that people have to actually use their fingers to move and touch the terminal point and click. At the same time, the current general mobile phone film needs to be conductive in order to be sensed by the touch screen.

In order to achieve interaction, the fingers need to be long and tired, the screen should be small, the electrical parameters of the touch screen should be sensitive, and the mobile phone film is not insulated, which restricts the development and use of mobile phones and brings unsafe factors to people.

Because the screen of the mobile phone is getting bigger and bigger, after being compatible with the functions of the computer, it is increasingly replacing the tablet. The mobile phone is a tablet computer. In this case, the large screen of the mobile phone cannot be operated with one hand at all.
