Abstract

This paper proposes a technique to allow blind software engineers to access the information held in Computer Aided Software Engineering (CASE) tools. Such tools support systems analysis and design methods that typically encode information as hierarchically structured two-dimensional graphs. The paper discusses the problems that blind engineers face in accessing this type of information by considering the structure of system models built in one Software Engineering notation, namely Hatley-Pirbhai Real Time Structured Analysis. It introduces a long established, but not widely used, notation, N2 charts, which provide an equivalent tabular encoding for many software engineering notations. This style of presentation is used, together with talking touch tablet, to provide an interactive means for blind software engineers to access full system models.
