Abstract : An earlier report described a physical analog of the human vestibular system, which simulated nystagmic eye movements and subjective sensation of motion based on sensed motion of the 'head.' This report reviews a number of possible extensions to this model--emphasizing the complex interactions among visual, otolith, and canal stimuli. Models are discussed for semicircular canals and otoliths, the vestibulo-ocular reflex, optokinetic and galvanic stimulation of eye movements, counterrolling, visual-vestibular interaction and pursuit eye movements.
