Leveraging Maps and Computer Vision to Support Indoor Navigation for Blind Travelers

利用地图和计算机视觉支持室内 为盲人旅行者导航 摘要 COVID-19使盲人或视障人士旅行的风险更大， 比大流行之前更困难。因此，视力受损的人可能会限制他们的视力。 必要的旅行，如前往医生的办公室，药房和杂货店购物， 为了锻炼或休闲而散步。因此，本COVID补充文件的目标， 并扩大了由家长赠款正在进行的工作，是开发一个新冠肺炎地图工具， 提供完全无障碍的非视觉地图访问。这个工具可以让视力受损的人 人们可以在舒适的家中探索地图和预览路线， 使用拥挤度数据规划沿着更安全、更少拥堵的路线。此外，该工具 将以完全可访问的形式提供各县的COVID发病率数据， 他们的长途旅行计划因此，该项目将为视力受损者提供 工具和信心进行更安全，更独立的旅行。

Leveraging Maps and Computer Vision to Support Indoor Navigation for Blind Travelers Abstract COVID-19 has made traveling as a blind or visually impaired person much riskier and more difficult than before the pandemic. As a result, people with visual impairments may limit their essential travel such as trips to the doctor’s office, the pharmacy and grocery shopping and walks for exercise or leisure. Accordingly, the goal of this COVID Supplement, which builds on and expands the work being conducted by the parent grant, is to develop a COVID map tool that provides fully accessible, non-visual access to maps. This tool will allow visually impaired persons to explore maps and preview routes from the comfort of their home, allowing them to plan their travel along safer, less congested routes using crowdedness data. In addition, the tool will present county-by-county COVID incidence data in a fully accessible form, which will inform their travel plans over greater distances. Thus, this project will give visually impaired persons the tools and confidence to undertake safer, more independent travel.
