Abstract:

     NASA is currently employing a pre-flight adaptation trainer
(PAT) to pre-adapt astronauts to conditions that cause space
motion sickness (SMS). This project will develop an approach that
will aid in enhancing the fidelity and effectiveness of this
device and its associated training regimens. Specifically, the
project will develop a "profile analysis" technique so that a
direct comparison of the pattern of SMS symptoms experienced aloft
and after re-entry can be made with the pattern obtained in the
PAT. The project will also develop a video-based measurement
technique to provide quantitative information concerning the
nature of the visual stimulus delivered to trainees in the PAT.
This two-phase methodology will help modify the fidelity of the
PAT configuration and will aid in verifying the effectiveness of
training received in the PAT. This effort will also produce a
biocybernetic video measurement technique that can be applied to
other space flight simulation and virtual environment systems in
which measurement of the visual stimulus for motion and
orientation is important.

Potential Commercial Application:

Potential Commercial Applications:  The availability of an
automated system that links visual display parameters (flow and
edge rate, pitch and roll rate, etc.) with the magnitude of the
perceptual experience can be used to provide engineering
specifications for all manner of virtual reality systems, whether
they are used for training or recreation.
