Abstract
The system produces movements in a home entertainment chair. It has a motor controller and a plurality of movement generator units for generating small amplitude and low frequency movements in the viewer's chair. The system is intended for home use and can be easily installed under each leg of a chair or of a sofa. The source of movement control signals can be derived from a video presentation soundtrack, and directional movement sensations can be created by inducing controlled movements in each leg of the viewer's chair.
