Tactile Directories of Building Interiors as Orienting and Way-Finding Aids for the Visually Impaired: A Prototype

A tactile map/directory designed to provide the visually impaired with directional and orienting information about the interior of a complex building was tested for efficiency of use by sighted, partially-sighted, and non-sighted individuals. Preliminary evaluations suggest that simpler, more schematic maps may be more effective as way-finding aids than was the detailed, more architecturally-true map tested. Tactile discriminability of symbols used to represent various interior building features was also compared in order to specify a highly discriminable symbol set.
