New device assists vision impaired to understand graphics
The tablet, called GraVVITAS uses a standard touch screen tablet PC combined with sound, vibration and voice prompts to help guide the user to read the diagram.
PhD candidate Cagatay Goncu who, along with Professor Kim Marriott is working on GraVVITAS said, “The basic idea is to guide the user to find the object by using sound. Touching the object causes the sound to stop and a voice explains what that object is and any other information associated with it.”
