Workshop: Tactile Graphics Production and its Principles

Presented by Petr Cervenka, Michaela Hanouskova, Lukas Masilko and Ondrej Necas.

  • Short introduction of technologies for preparing tactile graphics including demonstrations
  • Explanation of basic methods of adapting graphics for tactile perceiving
  • Practical production of hand-made tactile graphics with regard to the needs of blind people

The main goal of the workshop is to introduce teachers and transcribers to methods of transforming a printed or digital graphics to the form adapted for optimal tactile perception by blind users. The authors of the workshop start with several demonstrations of tactile graphics produced by different technologies so that the teachers and transcribers become aware of the pros and cons of these specific approaches.
Then they explain the basic methods of adapting graphics for tactile perceiving. They introduce different types of 2D graphics (pie charts, graphs within a coordinate system, diagrams, technical drawings, simple maps etc.) and discuss an optimal approach to adapt them for a blind student, including the cases when the adaptation for tactile perception is not suitable. They explain the necessary principles one should comply with when producing tactile graphics, such as to reduce irrelevant elements or to divide the graphics into several isolated parts in case of more complicated graphics, to prepare a template respecting minimal spacing between two objects (lines, areas, labels etc.) and other conditions or to think about a proper navigation system which enables blind users to use a more complex structure, etc. Finally, they hand in a list of different printed graphics to the participants and ask them to adapt it for tactile perceiving. Of course, this part of the workshop will be as interactive as possible and the workshop leaders will try to help and discuss with participants the best approach to the preparation of all these graphics for blind people.
