AudioGraph: An Empirical Investigation in Communicating Graphical Information to Blind Users


Dimitrios Rigas,

The University of Hull


AudiGraph was developed as an experimental framework program to investigate the effectiveness and applicability in using structured musical stimuli to communicate graphical information to blind users. Experiments performed under AudioGraph, communicated graphical space containing graphical objects (e.g. squares or circles), an auditory cursor to move around the graphical drawing area to locate, create, and edit graphical objects as well as select menu options to control the AudioGraph. Simple diagrams were also communicated to blind users. Understanding of diagrams improved when perceptual context was introduced. The results of these experiments enabled the development of a three-layer approach to auditory interface design.
