Using Remote Sighted Assistants to Identify the Location and Orientation of Visually Impaired Pedestrians

Indoor navigation is very difficult for people with visual impairments. Numerous technologies have been proposed for non-visually identifying the location and orientation of a pedestrian, but none has yet proven as successful as GPS for outdoor navigation. Smartphone apps have been developed in which visually impaired users send a camera snapshot of an object to a remote service for object identification. We asked whether a similar system could be used for indoor location sensing. An experiment was conducted to determine whether a normally sighted person, called the “interpreter”, could identify the location and facing direction of a photo taken by a simulated pedestrian in a building using a floor plan and a small number of representative photos from key locations within the floor plan.
