Sensorimotor performance and haptic support in simulated weightlessness [PDF]
Experimental Brain Research, 2020 AbstractThe success of many space missions critically depends on human capabilities and performance. Yet, it is known that sensorimotor performance is degraded under conditions of weightlessness. Therefore, astronauts prepare for their missions in simulated weightlessness under water.
