  • Alleviating motion, simulator, and virtual environmental sickness by presenting visual scene components matched to inner ear vestibular sensations
    Patent number: 6497649
    Abstract: Display of an independent visual background provides a visual reference corresponding to the perceptions of a person's vestibular system, thereby substantially reducing or eliminating motion sickness that otherwise occur due to a mismatch between the visual perception of motion or non-motion and the sensations of the vestibular system. If the person is wearing a head-mounted display (HMD), is in motion, or is in a moving environment, a motion tracking system or other motion sensors are employed to produce signals indicative of the motion of the environment and/or of the person. The signals produced are then processed using a vestibular model, producing a modified signal corresponding to the perception of motion by the person's vestibular system. Using this modified signal, the independent visual background is displayed to the user, providing a visual reference that corresponds to the perception of the vestibular system.
