Frameless multipoint touch man-machine interaction method and system based on radar eye

Abstract

The invention discloses a frameless multipoint touch man-machine interaction method and system based on a radar eye. The frameless multipoint touch man-machine interaction method includes steps of forming a radial laser scanning surface through the radar eye and detecting finger shading information of an operator; acquiring at least one monitoring point space position shaded by fingers through debugging software of the radar eye, converting the monitoring point space positions into projection screen plane coordinates respectively and controlling updating of output images according to the projection screen plane coordinates; displaying and outputting the updated output images. The devices include the radar eye, a host and a projection screen. The frameless multipoint touch man-machine interaction method and system based on the radar eye has the advantages of insensitivity to surrounding light, high interference resistance, reliability and accuracy in positioning, simplicity and convenience in implementing, low use cost, no frame limit, flexibility in use ways and wide use range.

Description

technical field [0001] The invention relates to the field of interactive multimedia display, in particular to a radar eye-based frameless multi-touch human-computer interaction method and system. Background technique [0002] The interactive multimedia display in the prior art mainly uses the infrared ray method to locate and track human body movements. Systems based on this type of technology include infrared camera capture systems, infrared touch frame systems, and the kinect camera system developed by Microsoft, etc. However, because the light and natural light itself contain different amounts of infrared light waves, which will interfere with the infrared rays used in the system, the system that uses this type of technology to capture often fails when the light is relatively bright or in an outdoor environment. Precise positioning, or even misjudgment of coordinate data, will cause the system to malfunction or be too sensitive, seriously affecting the use. And these tec...

Problems solved by technology

However, since the light and natural light itself contain different amounts of infrared light waves, which will interfere with the infrared rays used in the system, the system that uses this technology to capture the light will often appear in a brighter light or in an outdoor environment. Precise positioning, or even misjudgment of coordinate data, will cause the system to fail or be too sensitive, seriously affecting the use

And these technical deficiencies have largely restricted the application and development of interactive multimedia display methods in the entire exhibition industry.
