Demonstration of a Motion Coupled Virtual Environment (MOCOVE) -A Device for Reducing Spatial Disorientation in Uncoupled Virtual andMot ion Environments

摘要

The U.S. Navy intends to field Virtual Environments (VE) aboard ships and submarines for trainingcrews at sea and in harbor. The shipboard environment combined with a VE presents a challenge forreducing the side effects, most notably motion sickness, postural instability and spatial disorientation.The discrepancy between actual motion and perceived motion in the VE has been shown to be among thegreatest contributing factors to side effects. The two environments, virtual and real, combine to create ahighly provocative 'motion discordant environment.' This demonstration presents an approach forminimizing side effects. The approach creates a Motion Coupled Virtual Environment (MOCOVE)where physical motion is sensed and convolved with the VE scene. The resultant VE has been shown toreduce side effects in preliminary laboratory studies.
