Outline:• Introductions
Tactile vs. visual learningApproaches to adapting imagesGeneral practices
• Tactile terminology
• Tactile production methods
• Sample items
• Questions we face—small and large
Part I
Tactile vs. visual learning • systematic vs. instant• 2-D vs. 3-D• limited palette vs. range of colors,
shading, fonts
Success!
Approaches to adapting images
Giving necessary information
Understanding full intent of the graphic/task and how it "works"
Can we do it? If so…

Using lines & textures
Dealing with decorative elements
Changing 3-D perspectives
Omitting items

Our Questions and Yours• What elements do we add in (key, labels)
and when?
How will the tactile reader experience this image?
• How to depict purely visual concepts for blind readers?
Wider Issues
• Testing students in a medium different from the one they studied
• Cultivating tactile reading skills early on
Further Discussion
Thank you!
