Abstract: The purpose of the paper is to describe a set of techniques aimed at assisting visually impaired users build mental models of online geographic maps without the use of any special hardware beyond what is needed to support a web browser, mouse, and sound card. The methods described make use of auditory signals which serve as corrective feedback information for such users as they attempt to learn geographic data from these maps. The mental model is built by tracing paths and locating objects on the maps. We claim that the user's activity of tracing and location discovery constructs a mental model through motion of the hand, the reverse of the process by which blind users are able to draw objects which they have never seen. Results of users employing this method will be reported in a subsequent paper.
