Read the press release about Graphiti.

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 for the American Printing House for the Blind. This revolutionary display was developed in conjunction with the Transforming Braille project. 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 final 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.

Expert Review and Field Testing Begin Soon

APH and Orbit will begin field testing Graphiti in the fall of 2016.

The fall review will be with experts in the field of tactile graphics and assistive technology. Reviewers will test software, hardware, connectivity, and new features as they are implemented.

The spring field evaluation will be with teachers of students who are visually impaired, including students in elementary, middle, and high school.

Watch the APH News for details on dates and qualifications for expert reviewers and field evaluators.

Graphiti is expected to ship in late 2017 and may be available through APH’s Federal Quota Program in the U.S.

Generous Donor Supports Development of Graphiti

APH is grateful to the William M. Wood Foundation, Bank of America, N.A., Co-Trustee. They awarded a generous $200,000 for the development of the revolutionary Graphiti dynamic multilevel tactile touch display.
