AUDITORY INTERACTIVE MAP/NAVIGATOR FOR BLIND PEOPLE

拟议的新迎新辅助工具包括一张审计师互动地图 具有用于自动位置跟踪的子系统。它本质上是一种 会说话的地图，引导旅行者到达他/她的目的地 跟踪他们的位置。寻路模块提供了灵活的 访问地图/数据库，包括路线选择、搜索、 回溯和绕道功能。提供口头路线说明 使用语音合成。这个辅助设备是便携的，戴起来就像一个“随身听”。 卡式磁带播放机，它的设计是在不牺牲成本的情况下将成本降到最低 功能性。与使用GPS定位信息的系统不同， 位置跟踪是通过使用电子罗盘的独立模块来实现的 和惯性传感器。这避免了费用和信号接收 与卫星或无线电信标导航相关的问题。第一阶段 具体目标包括自动化职位的可行性论证 对室内和室外路线进行跟踪和路线指导。一个 另一个目的是演示路线说明汇编 只需少量投资即可实现。试点测试和焦点小组， 带有盲目的主体，将被用来优化原型设计。一个 正式评估，其中10名盲人受试者走一条不熟悉的路线 使用样机辅助，将构成可行性论证。

The proposed new orientation aid consists of an auditors interactive map with a subsystem for automated position tracking. It is essentially' a "talking map" that guides the traveler to his/her destination while keeping track of their location. A wayfinding module provides flexible access to the map/database, including route selection, search, backtracking, and detour functions. Verbal route instructions are provided using speech synthesis. The aid is portable and worn like a "walkman" cassette player, it has been designed for minimum cost without sacrificing functionality. Unlike systems that use GPS for positioning information, position tracking is by a stand-alone module that uses electronic compass and inertial sensors. This avoids the expense and signal reception problems associated with navigation by satellite or radio beacon. Phase I specific aims include a feasibility demonstration of automated position tracking and route guidance for both indoor and outdoor routes. An additional aim is to demonstrate that compilation of route instructions can be achieved with modest investment. Pilot tests and a focus group, with blind subjects, will be used to optimize the prototype design. A formal evaluation, in which ten blind subjects travel an unfamiliar route using the prototype aid, will constitute a feasibility demonstration.
