摘要
针对传统导航产品基于视觉的功能设计和人机界面不便盲人使用的弱点,在运行Windows Mobile系统的智能手机平台上,结合全球卫星定位系统(GPS)和地理信息系统(GIS),开发了适合盲人出行使用的导航软件系统。通过研发定制盲人专用地图数据源,改进迪克斯特拉寻径算法,完成适于盲人行走的最适路径规划;系统具备路线定制、短信求助和周边搜索等针对盲人用户的功能,实现了语音、按键等人机交互方式。
Traditional navigation products are designed for the visually normal people,the use of the blind community has been limited.By the integration of Global Positioning System with Geographic Information Systems（GIS）,a navigation software system specially designed for the blind is developed on the smart phone platform that running Windows Mobile system.This paper works out a navigation strategy special for the blind users by providing the custom-built map data and an optimized Dijkstra shortest routing algorithm.The software has the functions of route customization,location sharing and peripheral searching for the blind users.And the users can interact with the system by means of voice and buttons.
