Sensors able to detect three-dimensional motion have been commercially available for several decades and have been used in automobiles, aircraft and ships. However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion sensor technologies available commercially, there are four principle types of motion sensors which are important for Motion Processing in the consumer electronics market.
