ABSTRACT
In technical reports and papers interrelations are often represented as diagrams. With the aid of a touch panel and auditory display AudioGraf enables blind and visually impaired people to read such diagrams. The diagram is displayed on the touch panel where a part can be selected with a finger. The selected part will be auditorally displayed. If the finger is moved, another part is selected and auditorally displayed. This way the whole diagram can be explored in an audio-tactile way. A model of this audio-tactile exploration is presented. Based on this model it is explained how AudioGraf supports the user. Usability tests have shown that simple diagrams can be read by blind users within relative short time.
