A study of development of three-dimensional visual barrier-free device for individual locomotion with visual perceptual disorders

单侧空间忽略（USN）是一种常见的综合征，其中患者无法报告或响应来自脑损伤对面空间一侧的刺激，其中这些症状不是由于原发性感觉或运动缺陷。神经衰弱与损伤指标以及日常生活活动（ADL）残疾指标的表现较低相关。在这项研究中，我们开发了一个三维视觉无障碍设备，协助动态运动，如步行和轮椅操作，在个人的视觉知觉障碍。本研究的目的是调查是否有一个视觉信息系统与头戴式显示器（HMD）是有用的患者与USN。为了将HMD用作行走和轮椅辅助期间的提醒系统，我们还开发了可用于行走和轮椅操作的原型HMD支持设备。结果表明，由于视觉呈现和听觉刺激，该系统可以减少患者纠正姿势的反应时间。

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.
