Specification of Symbols Used in Audio-Tactile Maps for Individuals with Blindness

The implementation of multisensory environments in the field of map construction for individuals with visual impairments can be a challenging area for both users and designers of orientation and mobility aids. Audio-tactile maps can utilize a large amount of spatial information represented by audio symbols, tactile symbols, audio-tactile symbols (combined) and Braille labels. In regard to audio-tactile maps an important clarification needs to be elaborated and in particular what needs to be carefully examined is the basic query of which information should be presented in haptic mode and which information should be presented in audio or audio-haptic mode. In practice this means that a reasoned process of defining the appropriate symbols for audio-tactile maps should be implemented. The fundamental aim of project “ATMAPS” - Specification of symbols used on Audio-Tactile Maps for individuals with blindness” presented in this paper is the specification of symbols to be used in audio-tactile maps for individuals with blindness.
