中文摘要：

在高度信息化时代，盲人导航／路径诱导辅具已经成为盲人生活中的一部分，关系到盲人生活质量的好坏，体现了社会文明程度的高低。首先对盲人导航／路径诱导辅具总体情况进行了概述；然后基于结构特征进行分类，并分别介绍了电子式行进辅具、移动式导盲机器人、智能盲杖以及智能导盲系统等辅具的历史发展、应用现状；最后指出了今后的发展趋势以及存在的问题。从现时导盲研究工作表明，研制开发更具人性化更适合于盲人导航／路径诱导的辅助工具具有重要的实用价值和社会现实意义。

英文摘要：

In the era of high informatisation, the navigation/route guidance assistive devices for the blinds have become a part of the life for them. It relates to the quality of the life of the blinds and reflects the level of social civilisation. In this paper, first we outline the general situation of navigation/route guidance assistive devices for the blinds. Then we carry out the classification based on structural characteristics and introduce respectively the historical development and application status of the assistive devices such as electronic travel aids, mobile guide robot, intelligent blind cane, intelligent blind guiding system, etc. At last, we point out their development trends in the future and the prob- lems existed. Current research work on blind navigation shows that it has the important practical value and social reality significance to develop the assistive devices which are much humanised and more suitable to the navigation/route guidance for the blinds.
