Unilateral spatial neglect(USN) is a common syndrome in which a patient fails to report or respond to stimulation from the side of space opposite a brain lesion, where these symptoms are not due to primary sensory or motor deficits. Neglect is associated with lower performance on measures of impairment, as well as on measures of disability in activities of daily living(ADL). In this study, we developed a three-dimensional visual barrier-free device that assists dynamic movements, such as walking and wheelchair operation, in individuals with visual perceptual disorder. The aims of this study were to investigate whether a visual information system with a head mounted display(HMD) is useful to patients with USN. To use the HMD as a reminder system during walking and wheelchair ambulation, we also developed a prototype HMD supporting device that can be used for both walking and wheelchair operation. The results indicated that, because of the visual presentation and audio stimuli, the system could reduce the reaction time of patients to correct their posture.

单侧空间忽视(USN)是一种常见的综合征，患者无法报告或对来自大脑病变对面空间的刺激做出反应，这些症状不是由于初级感觉或运动障碍造成的。忽视与损害测量以及日常生活能力(ADL)残疾测量的较低表现有关。在这项研究中，我们开发了一种三维视觉无障碍设备，帮助视觉知觉障碍患者进行动态运动，如行走和轮椅操作。这项研究的目的是调查带有头盔显示器(HMD)的可视信息系统是否对USN患者有用。为了在行走和轮椅行走时使用头盔显示器作为提醒系统，我们还开发了一种既可以用于行走又可以用于轮椅操作的头盔显示器支撑装置原型。结果表明，由于视觉呈现和听觉刺激，该系统可以缩短患者纠正姿势的反应时间。
