A motion tracker is a sensor integrated into a VR interface that is able to track movement of body parts such as eyes, head, or hands in real-time. Typically they are optical based or inertia based. By tracking movement in real-time, they are able to have the system respond. Gesture and gaze control interfaces work in this manner, as do head trackers.

Motion sensors are starting to creep into a whole plethora of applications. They are the linch pins of haptics, of 3D pointers, of stress based sensor networks and locomotive VR interfaces. Yet, there's a problem. Small, discrete motion sensors, tiny enough to be built into larger devices the size say, of a Wii-remote or a 6 ounce HMD, are extremely difficult and expensive to produce.
