Researchers at the Massachusetts Institute of Technology in Cambridge, MA, have developed a system to track motion efficiently that have significant ramifications for computer game play and educational video. The researchers say that it will provide a cheaper and more efficient way torntrack motion, especiaily tor creating special effects for movies. Just imagine what this can do for kids learning a sport or perhaps learning to play a musical instrument.rnThe system uses a projector to send pulses of near infrared light - approximately 10,000 different patterns a second. When the patterns hit the tiny photosensors embedded in the subject's clothes, the photosensors capture the coded light and convert it into a binary signal that indicates the position of the sensor. Because the patterns of light will hit the sensors differently, depending on where they are,rneach sensor receives a unique light pattern.
