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

描述（由申请人提供）：Koronis Biomedical Technologies （KBT）提出开发一种小型，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。许多定位设备已经被创造出来，但到目前为止，它们都有主要的缺点，这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。这项新技术能够在没有任何特殊建筑基础设施的情况下跟踪建筑物内的位置。这个第一阶段项目的目标是建立一个小型、低成本的输入设备的可行性，该设备可以提供适合室内个人导航设备的位置和方向信息。在可行的情况下，第二期项目将开发一个生产原型，并结合室内数据库和视障用户界面，使用该输入设备进行人体试验。

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.
