DESCRIPTION (provided by applicant): This Phase II SBIR Project will develop an inexpensive, easy-to-use Indoor/Outdoor Navigation System (IONS) to assist and guide people who are blind. The system will follow a stored map, using GPS for location outdoors and providing location indoors with an inertial guidance system that is periodically updated and re-centered through a small number of light fixtures which are modulated to give a location signal while still providing non-flickering illumination. IONS will provide a seamless transition from outdoors to indoors, allowing one system to be used for all wayfmding. Users can access maps through wireless networks (WiFi) and can use IONS to create their own maps for later use or for sharing with blind friends. Phase I demonstrated the concept and showed performance indoors equivalent to verbal directions given by a skilled mobility specialist. This project will develop a more convenient optical sensor for users, improve system accuracy and audio guidance, and incorporate a commonly used mapping database. The project will develop software for use on more powerful computers and ultimately for use on personal data assistants (PDAs) and even cellphones. In Phase II the system will be installed in a commercial facility and its full indoor/outdoor capability demonstrated and evaluated in comparison with verbal wayfinding techniques by having subjects follow a route outdoors to the door of a building, then indoors to reach a specific destination. This system will help people who are blind to live and travel more independently and increase their opportunities and capability for employment. It will enhance their lifestyles and decrease their dependence on sighted people. The system should also have value for people with cognitive disorders and those who are unable to read signs or who would otherwise benefit from audio guidance in wayfinding. Products resulting from this project will be the computerized IONS system for wayfinding, the remote Talking Lights optical sensor and software.

描述（由申请人提供）：此第二阶段SBIR项目将开发一个廉价，易于使用的室内/室外导航系统（离子），以帮助和指导谁是盲人。该系统将遵循存储的地图，使用GPS进行室外定位，并利用惯性导航系统提供室内定位，该惯性导航系统通过少量的灯具周期性地更新和重新定心，这些灯具被调制以给出位置信号，同时仍然提供非闪烁照明。离子将提供从室外到室内的无缝过渡，允许一个系统用于所有的道路。用户可以通过无线网络（WiFi）访问地图，并可以使用IONS创建自己的地图供以后使用或与盲人朋友分享。第一阶段展示了这一概念，并在室内展示了与熟练的流动性专家给出的口头指示相当的性能。该项目将为用户开发更方便的光学传感器，提高系统精度和音频指导，并纳入常用的地图数据库。该项目将开发用于更强大的计算机的软件，并最终用于个人数据助理（PDA）甚至手机。在第二阶段，该系统将被安装在一个商业设施和其完整的室内/室外能力证明和评估口头寻路技术相比，有科目遵循一条路线户外的建筑物的门，然后在室内到达一个特定的目的地。该系统将帮助盲人更独立地生活和旅行，并增加他们的就业机会和能力。这将改善他们的生活方式，减少他们对视力正常的人的依赖。该系统也应该有价值的人与认知障碍和那些谁是无法阅读标志或谁将受益于音频指导在寻路。该项目产生的产品将是用于寻路的计算机化离子系统，远程Talking Lights光学传感器和软件。
