SENSORY PHYSIOLOGY AND MOTION PERCEPTION

The NASTAR Center

Current Ongoing and Completed Projects:

Adaptation to Coriolis

Adaptation to Coriolis Inducing Head Movements in a Sustained-G Flight Simulator
The reduction of unpleasant effects associated with sustained-G flight simulation using an adaptation training protocol may enhance the effectiveness of simulation.

Vehicle Roll Tilt

Human Orientation Perception during Vehicle Roll Tilt in Hyper-Gravity
In the primary experiment, Subjects will be placed in the cab of a long-arm centrifuge, spun up to the desired gravitational level and then be passively rolled in the dark to a series of angles at different rates.

Predicting Adaptation to Altered Gravity
This proposal is in response to a NASA and NSBRI Research Announcement and aims to develop a pre-flight sensorimotor adaptability assessment program that will identify those individuals who are likely to experience difficulty with gravitational transitions and sensorimotor adaptation and validate interventions or countermeasures.
Integrated Vibration and Acceleration Testing to Reduce Payload Mass, Cost and Mission Risk
It was demonstrated, through both simulation and test, that exposing a spacecraft to simultaneous acceleration and vibration loads can cause nonlinear structural responses, including shifts in natural frequencies, changes in mode shapes, and changes in the components that are excited.

Integrated Vibration and Acceleration Testing for Space Payloads
The goal of the research is to develop the capability to provide integrated acceleration, vibration, and shock testing using a state-of-the-art centrifuge (PHOENIX Centrifuge) at the NASTAR Center, in order to subject payloads to the synergistic effects of combined environments.

Transference of VR Based Sensorimotor Adaptation to Real Motion Environments
The goal of the project is to develop methods for adapting individuals in one environment (on Earth) that will lead to training benefits that will carry over to other environments (e.g. space).
Perception Modeling for Aircraft Accident Investigation
The goal of this effort is to develop a mathematical model of human spatial orientation perception and to determine, based on prior modeling efforts and experimental research, the general utility of the model in predicting spatial disorientation events and analyzing aircraft mishaps and accident scenarios.
