Clew Maps reimagines Clew as an app that crowdsources routes for indoor navigation and repurposes the existing backend code base to better serve this purpose by alleviating the pain points inherent to the current route-sharing mode of use. By implementing image anchoring to improve the robustness of the anchoring and alignment process, and by using a cloud database for route storage along with a new user interface (UI) to address the limitations of sharing routes in Clew, Clew Maps makes independent travel in unfamiliar public spaces more accessible for people with blindness and visual impairments (B/VI).
