Abstract
A motion-coupled visual environment prevents, reduces and/or treats motion sickness by sensing inertial motion and providing a corresponding evocative image for a subject to view. Inertial sensors may include accelerometers, gyroscopes or a variety of other different sensor types. A cross-coupling algorithm may be used to cross couple different sensed inertial motions. A variety of mapping schemes may be used to map sensed inertial motion to corresponding motion within the evocative scene displayed on the display. Driver-centric, passenger-centric and simulation surround systems are possible. Applications include reducing motion sickness on passenger vehicles such as airplanes, trains and cars; on military vehicles such as ships, airplanes, helicopters and the like; and reducing “cybersickness” in the context of simulations on moving platforms.
