“…A hybrid tactile overlay/haptic approach was employed in a networked application that allowed blind people to play a board game called Reversi (also called Othello) [26]. This used a touch screen with a tactile overlay to present the board and dynamic haptic and audio feedback to present the position of the pieces on the board.…”

Abstract. Access to graphics and other two dimensional information is still severely limited for people who are blind. We present a new multimodal computer tool, GraVVITAS, for presenting accessible graphics. It uses a multi-touch display for tracking the position of the user's fingers augmented with haptic feedback for the fingers provided by small vibrating motors, and audio feedback for navigation and to provide non-geometric information about graphic elements. We believe GraVVITAS is the first practical, generic, low cost approach to providing refreshable accessible graphics. We have used a participatory design process with blind participants and a final evaluation of the tool shows that they can use it to understand a variety of graphics -tables, line graphs, and floorplans.
