Orientation using guidance surfaces : Blind tests of tactility in surface with different materials and structures
All over the world, trials are taking place to make it easier for visually impaired people to orientate themselves in the physical environment. Guidance routes are being constructed using materials with many different types of structures on their surfaces. In Sweden there is a preference for certain kinds of surfaces for use on guidance routes, though their usability has not been tested in documented studies. The overriding purpose of this project is to identify structures for guidance surfaces and hazard warning surfaces that are usable for blind people who use a long white cane to navigate and orientate themselves. At the same time, however, these structured surfaces must not present an obstacle to people with diminished mobility.
