Novel patterns of visual-vestibular intersensory stimulation can result in symptoms of simulator sickness, raising health and safety concerns regarding virtual environment exposure. Two experiments investigated the effect of conflicting visual-vestibular cues on subjective reports of simulator sickness during and after a 30-min. exposure to a head-coupled virtual interface. This paper summarizes a few theories of motion/simulator sickness, lists some of the causal factors identified, and describes the potential causal factors examined in the experiments conducted.
