WAYFINDING SYSTEM FOR PERSONS WHO ARE VISUALLY IMPAIRED

描述：本提案描述了一种为视觉者提供的寻路系统 受伤了。通过使用成形磁场和近距离反馈 系统中，系统将同时呈现方位信息和实时 向盲人或视障用户提供信息。用户将收到 语音信息，使用传统的随身听收音机。 第一阶段的目标是确定这种无线电频率系统作为引导视障人士通过人行横道的一种方法的可行性。建议的目的是 计划是建立一个原型单元，并由具备以下条件的人员进行评估 视力不足，无法定位按钮杆，请参阅人行横道线或 从视觉上区分路缘。 该系统将结合定向和机动性进行开发 波士顿学院马萨诸塞州栗子山的专家将接受评估和测试 由盲人在现实的人行横道环境中使用。

DESCRIPTION: This proposal describes a wayfinding system for persons who are visually impaired. Through the use of shaped magnetic field and a close range feedback system, the system will present both orientation information and real-time information to users who are blind or visually impaired. Users will receive verbal information, using a conventional Walkman radio. The objective of Phase I is to determine the feasibility of this radio frequency system as a method to guide the visually impaired person through a crosswalk. The aim of the proposed program is to build a prototype unit and evaluate it by persons who have insufficient vision to locate a push-button pole, see crosswalk lines or visually distinguish a curb. The system will be developed in connection with orientation and mobility experts at Boston College Chestnut Hill, MA, and will be evaluated and testing by persons who are blind in a realistic crosswalk environment.
