Access to graphical information is a significant challenge for people who are blind and visually impaired. With the increased dependency on technology in schools, the lack of access to on-screen graphics can be an impediment to learning for students with visual impairments.

Graphiti is a dynamic multilevel tactile touch display developed by Orbit Research and the American Printing House for the Blind. Graphiti allows students and adults to access a wide variety of on-screen graphics by touch. This includes pie charts, bar graphs, geometric forms, maps, floor-plans, flow-charts, line drawings, and dynamic graphical content.

Graphiti’s breakthrough technology allows graphics to be depicted by means of an array of variable-height pins. To change to the next graphic, the pins on the refreshable display move up and down to create a tactile representation of the graphic. Graphiti can display topographical maps and other features such as grey levels and colors.

The current Graphiti unit pictured on this page is a prototype. The full-page unit consists of a 40 x 60 grid of variable-height, equidistant pins. Graphiti features the ability to detect touch, so the student can draw, zoom, or scroll directly on the display pins. Graphiti can display tactile versions of images of most file types.
