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. 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.
