A Laser Pointer/Laser Trails Tracking System for Visual Performance.

Visual performance with a large video projection screen is popular for various entertainment events such as DJ events. Some performers use computers to generate visuals, but using a keyboard or a mouse to control the visuals in front of a large screen is neither exciting nor intuitive for performers and audiences. We developed an interactive display system using camera-tracked laser pointers that enables performers to interact with the screen directly. The system can also detect shapes of the laser trails that enables the performer to move the laser pointers quickly. Most of existing systems employ color and pattern matching techniques that are not suitable for visual performance. [ABSTRACT FROM AUTHOR]
