Motion-coupled visual environment for prevention or reduction of motion sickness and simulator/virtual environment sickness
First Claim
1. A method for preventing, reducing or treating motion sickness of a user on a moving platform, comprising:
- sensing at least one inertial motion condition existing on said moving platform and providing signals responsive thereto;
processing said signals to provide display control signals; and
displaying, on a surface having first and second dimensions, at least one window for the user to focus on, and moving, based at least in part on said display control signals, the displayed position of said at least one window on said surface in both said first and second dimensions so as to correlate perceived motion with said sensed inertial motion.

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. 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.

17. In a system for preventing, reducing or treating motion sickness of a user on a moving platform, the system including a sensor for sensing at least one inertial motion condition existing on said moving platform, and a processor coupled to the sensor that processes said sensed inertial motion condition to provide display control signals for coupling to a display of the type that provides a display surface having first and second dimensions, said display displaying at least one window for the user to focus on, a memory device storing instructions for execution by said processor, said instructions causing the processor to move the displayed position of said at least one window on said display surface in both said first and second dimensions so as to correlate perceived motion with said sensed inertial motion.
