Aims:
- To examine the effects of stimulus frequency (0.01 -
0.6 Hz ) on adaptive changes in eye movements, motion perception and
cognition during combined tilt and translation motion profiles.
- To examine changes in control errors during a closed-loop nulling task before and after tilt-translation adaptation.
- To evaluate how a tactile prosthesis might improve control performance.
- To examine how spatial awareness is impaired with
changing gravitational cues during parabolic flight, and the extent to
which vibrotactile feedback of orientation can be used to help improve
spatial awareness.

Description:
This task contributed to gap closure by providing evidence regarding the physiological mechanisms and operational implications of disorientation and tilt-translation disturbances reported by crewmembers during and following re-entry. This task also validated the potential use of a vibrotactile prosthesis as a countermeasure by showing improved control of whole-body orientation during passive tilt and translation motion paradigm.
