Models and Mechanisms for Enhanced Sensory-Motor Control

摘要

The overall objective of the project is to develop quantitative models of human spatial orientation which can help the Air Force enhance missions involving accelerative environments. Our specific experimental and modeling objectives build upon our recently published model of static spatial orientation. The three-year objectives are: 1. Determine whether there is cross talk between axes during static body tilt on the three primary axes using a multi-axis indicator of the vertical; 2. Measure the subjective vertical during static body tilts involving displacements about several axes simultaneously; 3. Test whether velocity integration of position fails in Og, and determine whether it is augmented in 1.8g re 1g; 4. Determine whether somatosensory stimulation can be used a) to provide spatial reference cueing in Og to restore path integration, and b) to provide accurate perceived spatial displacement in 1.8g during CCCS. Two weeks of experimentation have been conducted in parabolic flight aboard NASA's C-9 aircraft.
