Personal Navigation System for the Blind using High-Sensitivity Indoor GPS

描述(申请人提供)：Koronis Biomedical Technologies(KBT)计划开发一种小型、低成本的室内个人导航设备。需要室内导航技术来支持视障人士的无缝移动。人们已经创造了许多定位设备，但到目前为止，它们都存在重大缺陷，限制了它们的广泛使用。近年来发展起来的高灵敏度室内GPS技术使室内GPS导航成为可能。这项新技术能够跟踪建筑物内的位置，而不需要任何特殊的建筑基础设施。该第一阶段项目的目标是确定创建一种小型、低成本的输入设备的可行性，该设备可提供适合室内个人导航设备的位置和方位信息。如果可行，第二阶段项目将开发生产原型，并使用输入设备结合室内数据库和视障用户界面进行人体试验。

DESCRIPTION (provided by applicant): Koronis Biomedical Technologies (KBT) proposes to develop a small, low-cost indoor personal navigation device. Indoor navigation technology is needed to support seamless mobility for the visually impaired. A number of location devices have been created, but thus far they all have major drawbacks, which limit their widespread use. Recently developed high-sensitivity indoor GPS technology makes indoor GPS navigation feasible. This new technology has the capability to track locations inside buildings without any special building infrastructure. The objective of this phase I project is to establish the feasibility of creating a small, low-cost input device that provides position and orientation information suitable for an indoor personal navigation device. If feasible, the phase II project will develop a production prototype and conduct human trials using the input device in conjunction with indoor databases and an interface for visually impaired users.
