Paper Abstract
This paper describes a monocular PSD-based motion capture sensor to employ with commercial video game systems
such as Microsoft's XBOX and Sony's Playstation II. The system is compact, low-cost, and only requires a one-time
calibration at the factory. The system includes a PSD(Position Sensitive Detector) and active infrared (IR) LED markers
that are placed on the object to be tracked. The PSD sensor is placed in the focal plane of a wide-angle lens. The micro-controller
calculates the 3D position of the markers using only the measured intensity and the 2D position on the PSD. A
series of experiments were performed to evaluate the performance of our prototype system. From the experimental
results we see that the proposed system has the advantages of the compact size, the low cost, the easy installation, and
the high frame rates to be suitable for high speed motion tracking in games.
