Using Blissymbolics to Develop Improved Tactile Symbols for Individuals with Communication Impairments

Abstract

This study focused on determining the feasibility of Blissymbols as the foundation for tactile communication for individuals with augmentative and alternative communication (AAC) needs. A commonly used method of AAC for these individuals involves tangible symbols, like real objects, which limit communication. For example, it is difficult to have tangible symbols readily available for the multitude of possible messages the user might want to convey. Blissymbols were chosen for the present study because they: 1) are minimalistic, which maximizes tactile processing; 2) are semantically combinatory in that they can be combined to represent new words and meanings; 3) are portable and provide a readily available large inventory of symbols; and 4) extend the range of communication environments.
