Simplified 2D Tactile Graphics for Non-Braille Readers

The DIAGRAM Center has been exploring whether it’s possible to make complex diagrams more appealing and engaging for tactile learners by adapting the 2D tactile graphics production process for non-braille learners. Innate in the traditional 2D production process are the simplification of visual content and the removal of things like clutter and perspective. These simplified graphics have the potential to better support students with special needs such as: cognitive disabilities, learning differences, autism, and low vision. While best practices highlighted in the Braille Authority of North America (BANA) guidelines for 2D tactile production process were applied in the experimental resources, several non-traditional versions were also created for testing: a version where braille is replaced by English text, a version where texture is replaced by vibrant colors, a version combining texture and color, and a version that provides a higher-level context of the original graphic.

The DIAGRAM Center has been working with Lucia Hasty from Rocky Mountain Braille Associates and Nicole Johnson, formerly with Central Access at Central Washington University and now a Ph.D. student at the University of Colorado, Boulder, on this project. A working draft of the design principles and assumptions used to produce these resources will be shared as this project progresses.
