Problems solved by technology

The existing touch technology (including various methods of image acquisition and processing) cannot reliably, effectively and conveniently realize the non-contact aerial operation of buttons, keyboards and touch screens
Resistive, surface acoustic wave, infrared and other touch screens must be touched to operate; the distance for capacitive screens to achieve non-contact operation is very short (generally no more than 3 cm), easy to misuse, and not practical; devices using image processing technology are not inevitable False occlusion means that the application site is difficult to install

Abstract

The invention discloses an infrared three-dimensional scanning structure and application thereof in an aerial touch screen and keys. According to the infrared three-dimensional scanning structure, L*Dinfrared transmitting tubes and L*D infrared receiving tubes are arranged on the bottom surface and the top surface of a cuboid infrared scanning area respectively; H*D infrared transmitting tubes and H*D infrared receiving outer tubes are arranged on the left side face and the right side face of the cuboid infrared scanning area respectively; in terms of an infrared aerial non-contact touch screen, an infrared three-dimensional scanning structure is arranged in front of a display screen in parallel; infrared aerial keys are of an infrared three-dimensional scanning structure and are arrangedright in front of the plane where all the keys are located in parallel, and gaps are formed between the infrared transmitting tubes, between the infrared receiving tubes and between the infrared scanning layers. Three-dimensional aerial positioning, non-contact aerial touch of the display screen and non-contact aerial pressing of the keys are realized, so that the problem of cross infection of viruses and bacteria caused by clicking of the touch screen and the keys in public places is solved.

Description

technical field [0001] The invention relates to the field of computer three-dimensional interaction, mainly relates to three-dimensional positioning and aerial touch technology, and specifically relates to the realization structure and method of three-dimensional aerial positioning and non-contact aerial touch based on infrared scanning. Background technique [0002] Three-dimensional interaction has always been an important topic in the field of computer intelligent interaction research. One of the technical difficulties in realizing 3D interaction is the accurate and reliable positioning of the human body (especially arms, hands, and fingers). At present, 3D aerial positioning is mainly realized by 3D image sensor, and Microsoft's Kinect is its typical representative. This positioning technology still has problems such as inaccurate positioning and wrong positioning, especially the inherent defect that its positioning is directional and cannot be solved. [0003] On the ...
