PREDATOR: A POSTURE TRACKING SYSTEM

The fields of telepresence and virtual reality have experienced a surge of activity in recent years. The goal of these fields is to place users in an immersive environment that behaves like the real world. To achieve this goal, fields require the use of next-generation input devices such as data gloves, head-mounted displays, and various other immersive peripherals. Posture capture and recognition offer a unified and more expressive means of interacting with computers.

This application brief presents a vision-based posture tracking system called Predator. Predator is a motion tracking system that allows a computer to unintrusively analyze the posture of the subject in real time. The package includes a vision processor based on the Texas Instruments (TIä) TMS320C40 digital signal processor (DSP) and includes a library of routines that makes it easy to write software that interfaces with Predator.
