Abstract

The invention discloses a wireless induction interactive system based on infrared light motion capture, which comprises a coordinate mapping method from a three-dimensional space point to a screen based on the infrared light motion capture. In the system, a position and a motion track of an infrared light-spot are captured by using an infrared camera and positioned at a corresponding position on a screen through a mapping algorithm, a control component on the screen is controlled and a novel three-dimensional space wireless induction interactive system is realized. The system expands a traditional simple control mode based on a remote controller and realizes the interactive control similar to a mouse for screen images in the three-dimensional space. Based on the interactive system, a screen menu can be controlled by gestures and postures and handwriting input can be realized after a handwriting recognition module is added. The system is very suitable for use in a digital home, and can expand the function of the traditional remote controller, realize television menu control and home control in the three-dimensional space and provide the application of media walls, interactive games, electronic whiteboard and the like.

Description

technical field [0001] The invention belongs to the technical field of human-computer interaction, and in particular relates to a wireless induction interaction system based on infrared light motion capture. Background technique [0002] With the continuous development of information technology and application services, people's demand for wireless sensing and interaction technology in three-dimensional space has become more and more urgent. Especially in terms of digital home and interactive games, the traditional remote control can no longer meet the needs of users. People urgently need to provide handwriting input and a strong interactive mode similar to the mouse to replace the simple button-based input and control of the traditional remote control. [0003] The current research hotspots mainly include interactive control methods based on video recognition and control methods based on gravity sensing. The interactive control method based on video recognition analyzes an...
