DESCRIPTION (provided by applicant): The objective of this phase II project is to use a new and innovative sensor technology called Doppler velocimetery (DV) for solving the problem of wayfinding indoors for the vision impaired. By performing a Doppler measurement of the floor movement relative to the walking person it is possible to determine the along-track velocity, the cross-track velocity and the vertical (up or down) velocity. With these measurements it is possible to accurately calculate real-time position inside a building relative to a starting point t an entrance. The significant innovation in this technology over other indoor navigation solutions for the vision impaired is that it does not require the installation of expensive infrastructure wihin a building to provide wayfinding. Wayfinding through an unfamiliar building for persons who are blind or have low vision is a challenging task. The ability of a person to move freely within publi and commercial buildings is an important factor for integration and independence of these individuals within educational institutions, work and social environments. This proposed technology has the potential of making a major impact by providing a practical indoor wayfinding solution for the vision impaired.

描述（由申请人提供）：该第二阶段项目的目标是使用一种称为多普勒测速（DV）的新型创新传感器技术来解决视力障碍者在室内的寻路问题。通过对相对于步行者的地板运动进行多普勒测量，可以确定沿轨道速度、跨轨道速度和垂直（向上或向下）速度。通过这些测量，可以准确计算建筑物内相对于入口起点的实时位置。与其他针对视力障碍者的室内导航解决方案相比，该技术的显着创新在于，它不需要在建筑物内安装昂贵的基础设施来提供寻路服务。对于盲人或弱视人士来说，在陌生的建筑物中寻找路是一项具有挑战性的任务。一个人在公共和商业建筑内自由行动的能力是这些人在教育机构、工作和社会环境中融入和独立的重要因素。这项拟议的技术有可能通过为视力障碍者提供实用的室内寻路解决方案而产生重大影响。
