Abstract
This paper examines the use of audio glances for giving an impression of the size, complexity and topology of abstract graphs. The first step in nearly all reading tasks, but particularly those of complex structured information such as equations, tables and diagrams, is a glance. This brief high-level overview of the information allows the reader to start to understand the nature of his task, and to develop strategies for reading. Yet a glance is currently unavailable to visually impaired readers. We describe an algorithm for generating earcons that present such glances through non-speech sound. An evaluation demonstrated that these were successful in conveying an impression of a graph to sighted volunteers. The success of this evaluation means visually impaired readers can now start their graph-based tasks with some of the benefits a glance can bring.
