  2. Editor for Linearization ofDirected and Undirected Graphs Motivation • Off-shoring needs, particularly within the field of IT, international standards for modelling and development. • UML (Unified Modelling Language) is an internationally successful standard. • UML is based on graphs and therefore not accessible with traditional methods for blind people. • High qualified IT specialists are increasingly deprived of the possibility of work because of the graphical notation of UML. • As far as we know, until now there has been no attempt to develop a program for editing or creating graphs for blind people.

  3. Editor for Linearization ofDirected and Undirected Graphs Application areas The use of graphs is not restricted to the IT business. Some examples illustrate the scope of using graphs: • Knowledge processing while designing complex buildings in architecture (adjusting by active, autonomous objects) to create blueprints. • Road building, computer aided design of road systems, underground nets, or even the planning of mobile task forces of fire brigades are shown as graphs. • In chemistry graphs are used to show structures of formulas. • Medical researchers use gene–gene or gene-environment models to learn about illnesses. • Dynamic modelling in machine construction is represented as graphs • In knowledge processing graphs are used to generate ontologiesi.e. for the „Semantic Web“.

  4. Editor for Linearization ofDirected and Undirected Graphs Previous work • TeDUB (Technical Drawings Understanding for the Blind):international project team within the framework of the European IST program (Information Society Technologies). • They develop software to explore technical designs and UML diagrams. • The navigation is made by keyboard, vocal output, and joystick. • The project is not yet concerned with the possibility to generate or change/edit graphs. • It concentrates on the recognition of the contents of existing graphs. • No development activities are possible with the existing solution.

  6. Editor for Linearization of Directed and Undirected Graphs Goals The University of Stuttgart is willing to take on responsibility for the following parts in a project: • Define an acceptable model for Europe with the possibility to reach an international standard. • Rules for the vocal output need to be provided. • Investigating transformation algorithms for conversion . • Various rendering processes to convert raw data into suitable application data. • Evaluate a generation mechanism to define new abstract classes and their characteristics. • Schemata to improve the import and export of XMI documents.
