Systems, methods, and software for providing wayfinding orientation and wayfinding data to blind travelers
Abstract:
To support the independence and mobility of blind pedestrians, the present inventors devised, among other things, free systems, methods, and software for providing narrative blind-ready wayfinding information. One exemplary system receives user input identifying a starting landmark and ending landmark in a particular selected geographic region, such as a city, university campus, government building, shopping mall, or airport. The system then searches a database for the corresponding narrative wayfinding instructions, and outputs them in the form of text or audio to guide a blind pedestrian from the starting landmark to the ending landmark. In the exemplary system, blind users select the geographic region as well as the starting and ending landmark from a voice-driven telephonic menu system and receive audible wayfinding instruction via mobile telephone. In some embodiments, the system also provides access to voice-driven restaurant menus.
