Knowledge about how to develop non-visual interfaces to diagrammatic information

It was possible to learn a lot as for non-graphical interfaces for diagrams, especially as for three topics:
- which information can be reported to help a blind to understand a diagram. For example as for floor plans it was useful to add descriptions of the shape of a room or about the number of doors and windows, etc.
- what is better to vocally output or Braille output. It was found that vocal output helps a lot to quickly explore a diagram only when particular captions are vocally output (i.e. the name of the node when reached). More descriptive information, as the methods and attributes for a class in UML class diagrams, can be output on display Braille so that more attention can be paid to its content.
- pros and cons of alternative output devices. The use of the joystick could bring great advantages especially to understand the positions of the nodes adjacent to a specific node.

What was learnt as for non-graphical representations of diagrams can be useful also in the future (i.e. when describing a diagram aurally or to propose enhancements to screen reading software).
