| Summary: | In this project, we built up a high speed interactive tabletop infrared tracking system, based on the existing Qualitrack system [1] [2]. This system can detect the position, orientation and state of each infrared emitting input device in real time. The output of Qualitrack is implemented according to standard TUIO protocol. Any applications software understanding TUIO protocol can be docked with Qualitrack smoothly. Based on the documents of the existing system, we built up the whole system architecture, the infrared pen, the infrared air hockey paddle and corresponding application software for Qualitrack system. As an in-house contribution, we created two new input devices, namely the magnifier and the color filter, to enrich the input device types of Qualitrack system. In order to explore the influence of tracking update rate on the user interaction performance, three user experimental tasks were designed and user studies were conducted. The corresponding user study application software was also developed. Key words: tabletop system, infrared tracking, TUIO protocol, user study
