本研究探讨了人类的表现上的一组基本任务，代表人类的互动在大多数虚拟环境（VE）系统。用户的运动控制，曝光时间，和场景的复杂性对人类的表现，存在和疾病的影响进行了评估。结果表明，以提高人类在虚拟环境中的表现，为用户提供完整的控制允许有效的性能固定的任务和那些只需要头部运动。然而，对于涉及头部和身体运动的任务，应该简化用户运动控制以提高性能并减少疾病。发现存在随着性能的提高而增加;因此，促进VE系统中的存在可能是有益的。然而，由于存在并没有随着长时间的接触而增加，而疾病却增加了，如果接触时间被用作增强存在同时减少疾病的工具，那么较短的接触可能会证明是有效的。
This study examined human performance on a set of basic tasks representative of human interaction in most virtual environment (VE) systems. The effects of user movement control, exposure duration, and scene complexity on human performance, presence, and sickness were evaluated. The results suggest that to enhance human performance in VEs, providing users with complete control allows for effective performance on both stationary tasks and those requiring head movement only. With tasks involving both head and body movement, however, user movement control should be streamlined to enhance performance and reduce sickness. Presence was found to increase with improved performance; therefore, it may be beneficial to promote presence in VE systems. However, because presence did not increase with prolonged exposure, whereas sickness did, if exposure duration is used as a tool for enhancing presence while decreasing sickness, shorter exposures may prove effective.
