Talking Tactile Tablet:

A Test Accommodation for Blind and Visually Impaired Students?

Working with TouchGraphics, inTASC examined the use of the computer-based Talking Tactile Tablet (TTT) as a test accommodation for blind and visually impaired students. The TTT is a peripheral device that provides a textured surface to allow users to "feel" diagrams and drawings. The TTT was originally developed to allow blind and visually impaired students access to maps and other resources produced by the National Geographic Society. In this study, we examined the feasibility of using the TTT to provide blind and visually impaired students access to mathematics items that include diagrams.
