GraVVITAS is a new multi-modal computer system to present accessible graphics to blind people. This system uses a multi-touch display for tracking the positions of the user's fingers. It also gives haptic feedback via small vibrating motors attached on the fingers, and uses audio (2D/3D) & speech feedback to guide navigation and to provide non-geometric information about the graphic elements.

GraVVITAS was originally developed during Dr.Goncu's PhD study by using a tablet PC on Microsoft Windows 7 platform.
