DESCRIPTION (provided by applicant): We are requesting funds to acquire a complete virtual reality motion system that is used to study spatial orientation, motion perception, as well as the planning and execution of eye, head, hand and arm movements in human subjects. This unique system consists of a motion platform with 6 degrees of Freedom, a head-mounted visual display, an eye tracker to measure eye movements and an Optotrak system to measure head, arm and hand movements. The motion platform delivers both linear and angular motions along any direction in space. The head-mounted visual display can provide optic flow or simulated motion through more naturalistic visual environments that are either congruent or incongruent with the motion of the platform. The human motion system will be used by each of the Users to study the effects of motion environments (established by congruent visual/vestibular stimuli or cue-conflicting situations) on spatial perception, motor control and coordination. It will be used for addressing basic science questions in both normal healthy human volunteers as well as in patients with spatial orientation and/or motor deficits. The human motion system will be housed within the newly constructed Central Institute for the Deaf building at Washington University School of Medicine. Deficits in spatial orientation and motor coordination in motion environments remain poorly understood but are vital for daily functions. In humans with subjective vertigo or balance difficulties, vestibular and spatial orientation deficits are often subtle and can only be revealed by innovative and quantitative spatial orientation and motor tasks. Millions of Americans suffer from balance related deficits, particularly in older aged adults, that can lead to injury or even death from falls. The requested system will allow for state-of-the-art basic science and clinical experimentation, as well as ensure a further growth in our research endeavors and an expansion in the collaborative efforts that are already strong among the motor control and balance communities.

描述（由申请人提供）：我们要求资金获得一个完整的虚拟现实运动系统，该系统用于研究空间取向，运动感知以及人类受试者的眼睛，头部，手和手臂运动的计划和执行。这个独特的系统由一个具有6个自由度的运动平台组成，标题视觉显示器，用于测量眼睛运动的眼镜跟踪器以及一个测量头部，手臂和手动运动的Optotrak系统。运动平台沿太空中的任何方向都提供线性和角运动。头部安装的视觉显示可以通过更自然的视觉环境提供视觉流或模拟运动，这些视觉环境与平台的运动是一致或不一致的。每个用户将使用人类运动系统来研究运动环境（通过一致的视觉/前庭刺激或提示冲突情况）对空间感知，运动控制和协调的影响。它将用于解决正常健康的人类志愿者以及空间取向和/或运动缺陷的患者中的基础科学问题。人类运动系统将安置在华盛顿大学医学院新建的聋人中央研究所内。 运动环境中空间取向和运动协调的缺陷仍然很了解，但对于日常功能至关重要。在具有主观眩晕或平衡困难的人类中，前庭和空间取向缺陷通常是微妙的，只能通过创新和定量的空间取向以及运动任务来揭示。数以百万计的美国人遭受平衡相关的赤字，特别是在老年人中，可能导致跌倒甚至死亡。要求的系统将允许最先进的基础科学和临床实验，并确保我们的研究努力进一步增长，并在运动控制和平衡社区中已经很强大的协作努力扩大。
