Designing Tactile graphics for blind
Tactile graphics are essential components of braille materials transcribed for use in educational and professional fields. Guidelines and standards for the inclusion, design, and presentation of tactile graphics are all the more necessary today with the advent of electronic text production and the proliferation of diagrams, illustrations, and graphs in educational texts.
Design principles which are relevant to these are given below
A tactile graphic is a representation of a print graphic designed in a manner that is the most meaningful to the reader. It is not an exact reproduction.
Cost and time must not be the primary considerations when determining the method of production. Choose the most effective production medium for each graphic.
Some eye-catching design techniques used in print, such as decorative borders, are irrelevant to the concept being taught and should be omitted.
A print graphic may be simplified as long as the original intent is not compromised.
If the concept of depth is not required, a 3-dimensional view should be changed to a 2-dimensional view.
Clutter occurs when components of the graphic are too close together or so similar that they become hard to distinguish tactually. Clarity of components is improved by creating a break (blank space) between adjacent textures or where lines cross other lines or textures.
Use transcriber’s notes to explain changes made to the print format.
There is more to making a graphic tactile than raising lines and adding braille labels
