A device and method which operates as an artificial labyrinth to eliminate sensory mismatch between the natural labyrinth/vestibular system and the vision system of an individual. The present invention provides an alternative means for the user to determine the true orientation of his body with respect to the surrounding environment. The method can be effected by means of a device which senses true body orientation and displays corresponding visual orientation cues that the brain can use to confirm other visual position information. The display can be projected into space in front of the user, directly onto the user's retina, or effected by pictorial scene averaging. The device is particularly useful in the rehabilitation treatment of persons suffering from vestibular nervous system defect or damage, and in providing relief to those suffering from the symptoms of nausea and/or vertigo which are often experienced as a result of the aforementioned sensory mismatch.

[ I claim:] [30.] A system for providing visual orientation information to a user, comprising:orientation sensing means for providing positional change information of an object moving with said user with respect to a baseline position of said user;data acquisition means to acquire said positional change information of said object moving with said user and said baseline position of said user from said orientation sensing means;data processing means for determination of a relative positional change of said object moving with said user from said baseline position of said user, based upon said positional change information of said object moving with said user and said baseline position of said user acquired by said data acquisition means; anddisplay means for presenting to said user a set of visual cues indicative of said relative positional change of said object moving with user.
