Task Description: Spaceflights can cause many sensorimotor-related difficulties that could jeopardize a mission. For example, if astronauts are forced to land manually onto the surface of Mars or the Moon, they will experience a rapid gravitational transition while dynamically stabilizing the spacecraft. In low-g and 0 g environments, gravitationally dependent vestibular and somatosensory cues are minimized and astronauts can easily become spatially disoriented. Vibrotactile feedback has been shown to improve performance of a variety of tasks such as navigation, driving, providing alerts, postural stabilization, rehabilitation, and sports. Additionally, it has been shown that vibrotactile cueing is useful in enhancing control of a motion platform, performance in helicopter flight, control of acrobatic flight in an aircraft, orientation of an astronaut in the International Space Station (ISS), and performance in a nulling task after returning from space. However, there are few controlled studies that have examined the effectiveness of vibrotactile feedback during a manual control task in a disorienting spaceflight analog condition that simulates gravitational transitions. Little is known about what types of training will ensure immediate and successful use of vibrotactile feedback during spatial disorientation felt during a gravitational transition. In Aim 1, we study whether specialized, context-specific training with vibrotactors is required to avoid loss of control when immediately transitioning to a condition without relevant gravitational cues. In Aim 2, we examine whether vibrotactile feedback given at points of stability is better than at points of danger.
