在环境认知方面研究更有效的方法，以帮助视障者在空间中走动，是残疾人无障碍的主要目标。事实证明，在改善通过周围环境寻找安全路径的流动性方面，以听力和回声定位线索为补充的流动性辅助工具是最困难的。如何在没有助听器和载体的情况下，克服单一构件对盲人步行者功能的限制，开发出适合盲人步行的设施，是一个必要的课题。实验的过程包括四个阶段;第一，寻路处理，以评估原始环境;第二，触觉地图位于路线的开始;第三，扶手添加沿着测试路线，最后，门的标志被放置在门上。每个阶段挑选15名视力受损者。结果表明，触觉地图和带有盲文地标的扶手在寻路方面比门牌更有效。扶手和门标志改善了触觉地图的局限性，将寻路的准确率提高到接近100%，并且在复杂环境中比在简单环境中更有效。
The study of more effective methods in terms of environmental cognition to assist visually impaired people in moving about in a space is the primary objective concerning the accessibility of disabled people. Mobility aids supplemented by hearing and echo-location cues have proven to be the most difficult concerning the improvement of mobility in finding a safe path through the immediate environment. How to develop facilities without auditory aids and carriers and to overcome the functional limitation of a single component for blind pedestrians is a necessary issue.A school with continuous space and a simple route and an office composed of open space and a complex route were selected as examples. The procedure of the experiment consisted of four phases; first, wayfinding was processed to evaluate the original environment; second, a tactile map was located at the start of the route; third, handrails were added along the test route, and finally, door signs were placed on doors. Fifteen visually impaired persons were selected for each phase. The results showed that both the tactile map and handrails with Braille landmarks were more effective in regard to wayfinding than were door signs. Handrails and door signs improved upon the limitations of a tactile map, raised the accuracy ratio of wayfinding close to 100%, and were more effective in a complex environment than in a simple environment.
