UPOWG#23 – Huntsville Feb N° 4 Objectives The purpose of this experiment is to investigate the effects of exposure to microgravity on the mental representation of spatial cues by astronauts during and after space flight. The 3DS will allow further identification of the role of gravity in the mental representation of 3D objects and environment by: 1.Evaluating the effects of microgravity on the mental representation of the 3D environment during long-duration space missions. 2.Using the free-floating condition to minimize orientation and cognitive references. 3.Distinguishing the effects of cognitive vs. perceptual motor changes. Experiment goals Expected results The results of this study could have important consequences for human performance during spaceflight. Indeed, a virtual reality training may be a way to train the astronauts to compensate for such altered spatial representation and enables to reduce disorientation and stress, to improve astronaut’s ability to manipulate objects or operate dexterous manipulators such as robotic arms, to better perception of the space habitat design by astronauts. 3D SPACE
