Abstract:
Graphical representations and diagrams are widely used in engineering disciplines. In computer science and electrical engineering, Unified Modeling Language (UML) diagrams, electronic circuit schematics, and Karnaugh-Veitch (KV) diagrams are commonplace. At our university, they are taught in courses of Technical Informatics and Software Engineering. However, these visual methods pose considerable barriers for students with visual impairments. Hence, using graphical representations is limiting educational accessibility and inclusivity. In response, this paper presents text-based alternatives which we have been using since three semesters to provide equivalent conceptual information in non-visual ways.
