Diagram navigator module

This is software that provides a means for blind people to read certain types of technical diagram using a screen reader and other equipment. Input into the system is through 'TeDUB' XML format and, for UML diagrams, some versions of the XMI interchange format. The software provides a representation of the diagram and support for domain-specific tasks in an accessible format. The primary information is presented to the blind user through the user's screen reader; additional information can also obtained by using low-cost joysticks. The software currently supports digital circuit diagrams, floor plans and most UML diagrams. It is the last of these in which the tool is most successful.

The tool provides one of the very few ways through which blind people can gain access to technical information. We envisage it as being of most interest to blind people involved in software engineering; either as professionals and students. The tool will be made available for use free of charge.
