Research and Implementation on Multi-touch Whiteboard System
Based on the technology of computer vision, a lowcost multi-touch whiteboard system has been developed. This paper firstly introduces the whole structure of the whiteboard system, then discusses the details of the system, including the design of the hardware, the middleware and the application software, and finally indicates a fast blob tracking algorithm. The experiment result shows that the system has a high sensitivity and meets the requirement of a real-time system. This multi-touch whiteboard can be widely used in the areas of digital teaching and commercial office, which have good market prospects.
