Abstract:
An apparatus for relieving motion sickness, comprising:at least one sensor which senses a motion of an object;a sensory converter coupled to said sensor and configured to convert said sensed motion to corresponding sensory signals having a variation in spectral emphasis in proportion to said sensed motion, comprising:a first mechanism configured to vary said spectral emphasis including at least one of 1) a bandwidth and 2) a center frequency of a first frequency range of said sensory signals in proportion to a sensed pitching motion of said object, anda second mechanism configured to vary said spectral emphasis including at least one of 1) a bandwidth and 2) a center frequency of a second frequency range of said sensory signals in proportion to a sensed yawing motion of said object; anda presentation mechanism configured to present said sensory signals to a user.
