ABSTRACT:
Galvanic vestibular stimulation is combined with visual stimulation to extend movement and directional cues within a virtual reality scene. The vestibular sensory system will be stimulated through the use of galvanic stimulation to induce a state of vestibular dysequilibrium. Synchronizing this inner-ear dysequilibrium with an optical reference will amplify the user's postural movement. The current state of virtual reality stimulates principally only the visual scene of the user through head mounted visual display units. However, the human body uses three different senses to resolve motion and acceleration cues like those simulated in virtual reality. Reliance on the visual scene, therefore, necessarily invites conflict between the visual system and the two remaining centers for motion sensation which remain dormant and, therefore, do not reinforce the visual sensations. This confuses the user and detracts from the experience. The instant invention negates this distraction through the use of galvanic stimulation of the user's vestibular system utilized in conjunction with the visual stimulation within virtual reality environments.
