GISTA--A GIS BASED TRAVEL AID FOR LOW VISION USERS

在社区和社区旅行的能力对 盲人或视力障碍者的生活质量。至 充分享受生活在一个社会中的好处(经济、社会、 教育、娱乐、宗教、政治等)，人们必须 能够有效地冒险外出，而不担心迷失方向和 依附性。经常伴随着视力障碍的行动不便 可能是毁灭性的，无论是在经济上，还是在心理和 身体健康。该项目的目标是创建一个基于地理信息系统的便携式 电子旅行辅助工具(GISTA)将增加个人的 通过提供准确、可靠的路线指引实现自主移动性 按需提供信息。先进的微电子和软件技术 让这一切成为可能。在第一阶段，将建造一个原型。一个 全球定位系统(GPS)接收器，电子航位推算 模块(DRM)和创新的地理定位软件将准确 确定用户的位置。路径搜索信息存储在 笔记本电脑上的地理信息系统(GIS)数据库将 通过语音合成器传送给用户。GISTA‘s 作为定向辅助工具的有效性将通过传导场进行评估 在一名视障人士的指导下进行测试 定向和移动专业人员。 建议的商业应用： GISTA是为视力障碍者设计的，但也将是 可销售给更多的行人，包括游客， 摩托车手、士兵、送货员、修理工和执法人员 官员，需要准确的地理位置。GISTA也可用于数据 收集(测绘)和跟踪：儿童、动物、缓刑犯、 机器人等。随着GPS的出现，对精确地理定位的需求正在迅速增长 1996年销售额为20亿美元，预计到2010年将增至80亿美元 2000年，为商业化提供了良好的环境 GISTA。

The ability to travel in the neighborhood and community is crucial to the quality of life of people who are blind or have visual impairments. To fully enjoy the benefits of living in a society (economic, social, educational, recreational, religious, political, etc.), people must be able to venture out efficiently, without fear of disorientation and dependency. The loss of mobility that often accompanies visual impairment can be devastating, both economically, and in terms of psychological and physical health. The project goal is to create a portable GIS-based electronic travel aid (GISTA) that will increase the individual's independent mobility by providing accurate, reliable wayfinding information on demand. Advanced micro-electronic and software technology makes this possible. In Phase I, a prototype will be constructed. A Global Positioning System (GPS) receiver, electronic dead reckoning module (DRM), and innovative geolocation software will accurately determine the user's location. Wayfinding information stored in a Geographical Information System (GIS) database on a laptop computer will be communicated to the user by a speech synthesizer. GISTA's effectiveness as an orientation aid will be evaluated by conducting field tests using visually impaired subjects under the direction of an Orientation & Mobility professional. PROPOSED COMMERCIAL APPLICATIONS: GISTA is designed for people with visual impairments, but will also be marketable to a much larger group of pedestrians, including tourists, bikers, soldiers, delivery people, repairmen and law enforcement officials, needing accurate geolocation. GISTA can also be used for data gathering (mapping) and for tracking: children, animals, probationers, robots, etc. Demand for accurate geolocation is growing rapidly, with GPS sales of $2 billion in 1996 expected to increase to $8 billion by the year 2000, providing a favorable environment for commercialization of GISTA.
