Expected in 2017: a Revolution in Accessing Digital Tactile Graphics
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
<http://transformingbraille.org/> .
Graphiti will allow 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.
