Integrating a Motion Base into a CAVE Automatic Virtual Environment: Phase 1

摘要

Four research issues to determine the technical feasibility of adding motion to a CAVE Automatic Vehicle Environment (CAVE) were investigated: what is the most effective motion base configuration. which vehicle cues are best presented through the motion base, which vehicle cues are best presented through the visual display, and how should the visual scene be compensated based on the movements of the motion base and the driver. A CAVE-based motion simulator was developed. Researchers drove the simulator to evaluate its performance with several different motion, head tracking, and visual compensation schemes. The primary results were: drivers perceived little difference between head tracking methods; roll, pitch, and vertical cueing were best presented through the motion base; visual scene compensation requires more research; the simulator as developed requires higher visual update rates to be effective; and finally simulator sickness may be an issue and needs to be investigated further. Successful system development may support TACOM's vehicle design process.
