研究目的：本研究假设通过补偿性感觉通道提供适当的知觉和概念信息可以帮助盲人进行预期探索。该研究的两个主要目标是：不同的方式（触觉和音频）和导航工具的评价;和空间认知映射的人谁是blink.Design/方法/方法，在这项研究中的BlindAid系统，它允许用户探索一个虚拟的环境，开发和测试的评价。该研究包括四名参与者谁是完全blind. Findings-初步研究结果证实，该系统使参与者能够开发全面的认知地图，通过探索虚拟环境。BlindAid系统可作为O&M康复训练的训练模拟器，作为O&M诊断工具，并支持盲人提前探索和收集空间信息。独创性/价值-本初步研究旨在突出哪些VE属性可以提供感知和概念空间信息，并允许盲人用户收集和扩展他们的空间信息。
Purpose–This research is based on the hypothesis that the supply of appropriate perceptual and conceptual information through compensatory sensorial channels may assist people who are blind with anticipatory exploration. The two main goals of the research are: evaluation of different modalities (haptic and audio) and navigation tools; and evaluation of spatial cognitive mapping employed by people who are blind.Design/methodology/approach–In this research the BlindAid system, which allows the user to explore a virtual environment, was developed and tested. The research included four participants who are totally blind.Findings–The preliminary findings confirm that the system enabled participants to develop comprehensive cognitive maps by exploring the virtual environment. The BlindAid system could be used as a training‐simulator for O&M rehabilitation training, as a O&M diagnostic tool, and to support people who are blind in exploring and collecting spatial information in advance.Originality/value–This preliminary study aims to highlight which VE properties could provide perceptual and conceptual spatial information and allow users who are blind to gather and expand their spatial information.
