Large Screen Multi-Touch System Integrated With Multi-Projector
A large screen multi-touch system integrated with multi-projector is presented in this paper. It uses multiple infrared cameras behind the screen to capture the image changes in multi-user finger contact surface, filters the visible light images projected by projectors, collects the remaining infrared image and transfers it into a computer, then detects and tracks various operations of multifingers via image recognition algorithm. The experimental results show that this system can support multi-users to use their fingers to accurately simulate actions of mouse clicks, synchronous positioning and trigger detection, and operations of selecting, moving, rotating and zooming target objects on large screen. This system has wide application prospects in real-time human-machine interaction.
