SBIR Phase II: Individualized Guidance for the Blind (IGB)

这个小企业创新研究（SBIR）二期项目将开发一种盲人个性化指导系统，这是一种准确、价格合理、易于使用的室内/室外辅助导航系统，帮助盲人找路和旅行。在另一项单独的努力中，一个使用GPS进行户外定位的盲人寻路系统正在设计和建造中。然而，对于室内使用，该系统需要一个复杂的惯性制导系统来定位和制导。在这个项目中，廉价的光学定位器将用于改善室内寻路，并在室内提供类似gps的定位。开发的软件将为盲人定位器提供个性化指导，在室内提供类似gps的定位信息，并允许将位置输入个人数据助理（PDA），更新位置并消除错误。作为一种商业产品，应用领域将包括医院、护理设施、博物馆、商场、学校、零售商店、贸易展览、交通设施和其他盲人和视力有限的人需要导航辅助的场所。

This Small Business Innovation Research (SBIR) Phase II project will develop an Individualized Guidance for the Blind system which is an accurate, affordable, easy-to-use indoor/outdoor assistive navigation system to aid people who are blind in wayfinding and traveling. In a separate effort, a wayfinding system for the blind using GPS for outdoor location is now being designed and built. For indoor use, however, this system requires a complex inertial guidance system for location and guidance. In this project, inexpensive optical locators will be used to improve indoor wayfinding and supply GPS-like location indoors. Software developed will allow Individualized Guidance for the Blind locators to provide GPS-like locator information indoors and permit the input of location to the personal data assistants (PDA), updating of location and elimination of errors. As a commerical product, application areas will include hospitals, care facilities, museums, malls, schools, retail stores, trade shows, transportation facilities and otherplaces where blind and people with limited vision require navigation assistance.
