A Comprehensive Examination of Electronic Wayfinding Technology for Visually Impaired Travelers in an Urban Environment
Martin Swobodzinski
Amy Parker
Human wayfinding and navigation are key organizing activities that allow human beings to acquire knowledge about the environment and develop cognitive representations in support of such essential tasks as route planning and travel. These activities are non-trivial in that they afford the activation of various cognitive systems and functions pertaining to wayfinding and navigation. Irrespective of the continuing proliferation of electronic travel aids and their evident facilitation of human wa...
