Motion sickness MS represents a challenge to many warfighters, particularly those in command and control vehicles C2V. Research by the U.S. Army and NASA suggests that as many as 90 of operators in a C2V experience some performance decrements and MS symptoms. Common solutions to MS emphasize pharmacological interventions, such as promethazine and dimenhydrinate Dramamine trade mark. The challenge with these approaches is that they often lead to decrements in cognitive performance and drowsiness. The sensory conflict theory suggests that MS arises in conditions where the sensory systems, specifically the visual and vestibular systems, detect different motions. This paper provides evidence for an information technology solution to MS, called Motion Coupled Visual Environment MOCOVE,2 which attempts to resolve MS by artificially introducing couplings between visual and vestibular motion cues.
