Scientists Develop Computer Mouse for the BlindBy AT Journal, Vol. 57, No. 1
Publication Date: September 2002
Article describing the prototype Vibrating Mouse, which is combined with sonic representations of graphs for people who are blind or have low vision. The mouse is placed on a line graph. Every time the mouse meets a line on the graph, it vibrates, giving the user a tactile tip to its placement. Sound graphs were developed to complement the line graphs. Lines on a graph were represented by tones that would vary in pitch according to whether the line was rising or falling. Several tones could be used to represent different lines of the same graph.
