Screen or projection non-contact type interaction device based on motion capture

Abstract

The invention provides a screen or projection non-contact type interaction device based on motion capture. The device comprises a light emitting and movement sensing part, a light receiving part and a resolving part. The light emitting and movement sensing part emits light of at least two wavelengths, the light is focused into a light spot on the area of a screen or projection, and meanwhile the movement track and posture of the light emitting and movement sensing part are collected and recognized to serve as a man-machine interaction operation instrument; the light receiving part collects a focused pattern of the emitted light on the screen or projection; the resolving part resolves the relative coordinates of the current light spot relative to the screen or projection, meanwhile receives the operation instruction based on the movement track and posture of the light emitting and movement sensing part, and transmits the relative coordinates of the light spot and the operation instruction of the light emitting and movement sensing part to another processor with a calculation function. The device has high interactivity and entertainment and has wide promotion significance.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a screen and projection non-contact interaction device based on motion capture. Background technique [0002] The current non-contact interaction methods for screens or projected images are either solved by gyroscopes, acceleration sensors, geomagnetic sensors, etc., with poor accuracy and accumulated errors. Either use image recognition to identify gestures and perform complex image processing algorithms, which is costly and has a low recognition rate. There has not yet been a real-time non-contact interaction based on screens and projectors with no cumulative error and high precision. The device appears. There is no method of combining the operator's motion trajectory with high-precision non-contact interaction based on screens and projectors. Contents of the invention [0003] Aiming at the deficiencies of existing interactive devices, the purpose of the present i...
