Despite significant effort on novel wireless and mobile applications for sighted people, novel wireless and mobile applications to improve the wellbeing of visually impaired individuals remain largely underexplored. The biggest everyday challenge for visually impaired individuals is safe and quick navigation to reach a desired destination in unfamiliar outdoor/indoor environments. Outdoor navigation for unsighted people can be greatly facilitated by GPS-based aids which unfortunately do not work in indoor environments lack of GPS signals. This proposal outlines a challenging research plan on developing, prototyping, and evaluating a secure and usable indoor navigation system for the visually impaired. The scientific promise of the proposed research will expand the fundamental understandings about indoor navigation for the visually impaired with the potential to open a new research direction. Successful development and implementations of the proposed techniques will have profound impact on allowing visually impaired individuals to have indoor navigation and wayfinding as sighted people, thus significantly improving the mobility and wellbeing of millions of visually impaired users in the US and around the world. The proposed research consists of six main research thrusts. The first thrust is to investigate novel crowdsourcing-based techniques to construct accurate indoor floor plans for arbitrary indoor venues with or without large open spaces. The second thrust is to develop secure cooperative techniques to detect and minimize the impact of fake mobility traces submitted by dishonest crowdsourcing workers. The third thrust is to investigate crowdsourcing-based construction of an indoor image database that can well characterize and visualize an indoor venue. The fourth thrust is to develop crowdsourcing-based techniques to enable accurate point-to-point indoor navigation for the visually impaired. The fifth thrust is to investigate novel techniques that can provide visually impaired individuals enhanced indoor navigation experience similar to what sighted persons can get. The last thrust is to implement the proposed indoor navigation system and thoroughly evaluate its efficacy, efficiency, and usability.

尽管为视力人员提供了新颖的无线和移动应用程序的巨大努力，但新型的无线和移动应用程序以改善视力障碍者的福祉，但仍未得到充满兴趣。对于视力障碍的人来说，每天最大的挑战是安全，快速的导航，可以在不熟悉的室外/室内环境中到达所需的目的地。基于GPS的艾滋病可以极大地促进不远人的户外导航，这不幸的是在室内环境中没有缺乏GPS信号。该提案概述了一项充满挑战的研究计划，该计划旨在开发，原型制作和评估视力障碍的安全且可用的室内导航系统。拟议研究的科学承诺将扩大对视力障碍的室内导航的基本理解，并有可能打开新的研究方向。拟议技术的成功开发和实施将对允许视觉障碍的个人作为视力远处的室内导航和寻路，从而显着改善美国和世界各地数百万视觉障碍用户的福祉。拟议的研究由六个主要研究推力组成。第一个推力是研究基于众包的新型技术，以构建具有或没有较大开放空间的任意室内场所的准确室内平面图。第二个推力是开发安全的合作技术，以检测和最大程度地减少不诚实的众包工人提交的假移动痕迹的影响。第三个推力是研究基于众包的室内图像数据库的构建，该数据库可以很好地表征和可视化室内场地。第四个推力是开发基于众包的技术，以使视力受损的准确点对点室内导航。第五个推力是调查可以为视觉障碍的个体提供的新技术，增强了与视力人所能获得的相似的室内导航经验。最后的力量是实施拟议的室内导航系统，并彻底评估其功效，效率和可用性。
