New Motion Tracking Device

Researchers at MIT have invented a motion tracking device that is much cheaper and more efficient than normal motion tracking devices. The device is called Second Skin. Instead of using high speed cameras and special markers to track motion, Second Skin just uses a projector and photosensors. Traditional motion tracking devices cost hundreds of thousand of dollars and can only be used in specially lit settings. Second Skin only costs a couple thousand dollars and can be can be used in almost any setting. The way Second Skin works is the projector sends out infrared light which hits the photosensors worn by the object being recorded. The pattern of infrared that hits the photosensors is recorded and converted into binary code and then sent to a computer which calculates the motion. This technology is very useful in movie making.
