   It is now known that motion detection in vision is based on the Hassenstein-Reichardt detector model. [31] This is a model used to detect correlation between the two adjacent points. It consists of two symmetrical subunits. Both subunits have a receptor that can be stimulated by an input (light in the case of visual system).

   Motion controllers became more widely distributed with the seventh generation of video game consoles. The Nintendo Wii console's Wii Remote controller used an image sensor [5] so it could be used as a pointing device along with an accelerometer to track straight-line motions and the direction of gravity. The Nunchuk accessory for use in a ...
