Using an audio interface to assist users Who are visually impaired with steering tasks

摘要

In this paper we describe the latest results in our on-going study of techniques to present relational graphs to users with visual impairments. Our work tests the effectiveness of the PLUMB software package, which uses audio feedback and the pen-based Tablet PC interface to relay graphs and diagrams to users with visual impairments. Our study included human trials with ten participants without usable vision, in which we evaluated the users' ability to perform steering tasks under varying conditions.
