“…McFarland showed that lead filters could introduce substantial magnitude distortion, while Cardullo and George (1993) found that McFarland's predictor provided the best trade-off between performance and accuracy. Therefore, McFarland's was chosen to calculate the predicted motion base position.…”

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.

“…The results of numerous investigations conducted within the context of flight simulation have demonstrated the benefits of using algorithmic prediction methods for manual control tasks. Although not perfect, this approach has been shown to (a) increase pilot-vehicle performance, (b) reduce pilot workload, (c) increase pilot-vehicle stability, (d) reduce training time, and (e) increase handling quality ratings (Cardullo & George, 1993;Crane, 1983;Hess & Myers, 1985).…”

his chapter addresses the negative effects of time-delayed visual feed-T back on perceptual-motor performance in virtual environments and describes the results of an empirical evaluation designed to compare two methods of compensating for these effects. The first method, termed the algorithmic prediction method, derives from an engineering perspective in which attempts are made to extrapolate user input data (i.e., physical movement of the eyes, head, arms, legs; etc.) into the future by the amount of time delay in the system, thereby canceling the disruptive effects of the delayed feedback. The second method of compensation, termed the perceptual adaptation method, is a behavioral solution based on the recognition that human beings possess a remarkable capacity to adapt to perceptual modifications of their environments. This latter notion, that human beings exhibit adaptive perceptual systems or perceptual plasticity, was first introduced to the primary author through the works of William Dember (Dember, 1960;Dember & Warm, 1979). In particular, a chapter titled "Effects of Learning on Perception," which appeared in the first edition of his book "Psychology of Perception" ( 1960), was especially influential in the way I came to understand and think 579
