This application seeks further support for the development of a wayfinding system specifically for building interiors of the facilities of public accommodations (e.g. office buildings, transportation facilities, hospitals, etc.) that will increase accessibility of those facilities to visually impaired users and serve as an environmental rehabilitative intervention for vision loss. This computerized system, called Pathfinder, interacts with users using artificial speech, voice recognition, electronic tactile touch tablet, and a high contrast visual CRT display. Embodying principles of universal design and intended to be useful for all users, including fully-sighted, the system will also increase accessibility for wheelchair users and hearing-impaired persons. Phase I results demonstrated feasibility with blind users unfamiliar with one floor of a Manhattan office building, and showed that the system is capable of training users with no experience with visual or tactile maps on its use without human intervention. Phase II research will address further development of the physical design of the product, the user training module, the tactile and voice recognition interfaces, and the visual display for low vision. Additionally, computer programming tools for building map and signage design professionals will be developed and tested. The product, along with an instructional package will be commercialized in Phase III.

本申请寻求进一步支持，以开发 专门用于设施的建筑内部的寻路系统 公共设施（如办公楼、交通 设施、医院等）这将增加那些 为视障人士提供设施，并作为一个环境 视力丧失的康复干预。 这个计算机化的系统， 名为“探路者”，使用人工语音和声音与用户互动， 识别，电子触觉触摸板，以及高对比度视觉 CRT显示器。体现通用设计原则，旨在 对所有用户都有用，包括全视力，该系统还将 为轮椅使用者和听障人士提供更多无障碍设施 人士 I期结果证明了盲人用户的可行性 不熟悉曼哈顿办公楼的一层， 该系统能够培训没有经验的用户， 视觉或触觉地图上的使用，而无需人为干预。 二期 研究将解决进一步发展的物理设计， 产品、用户培训模块、触觉和语音识别 接口，以及用于低视力的视觉显示器。 此外，本发明还 用于建筑地图和标识设计的计算机编程工具 将培养和测试专业人员。 该产品，沿着 第三阶段将把教学材料商业化。
