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.

单方面空间忽视（USN）是一种常见综合征，其中患者无法报告或对脑病变相对的空间侧面的刺激做出反应，其中这些症状不是由于原发性感觉或运动缺陷引起的。忽视与降低损害措施以及日常生活活动（ADL）的残疾度量有关。在这项研究中，我们开发了一种三维视觉屏障设备，该设备有助于视觉感知障碍的个体，有助于动态运动，例如步行和轮椅操作。这项研究的目的是研究具有头部安装显示器（HMD）的视觉信息系统是否对USN患者有用。为了在步行和轮椅上使用HMD作为提醒系统，我们还开发了一种原型HMD支撑装置，可用于步行和轮椅操作。结果表明，由于视觉表现和音频刺激，该系统可以减少患者的反应时间以纠正其姿势。
