Abstract

Existing drawing tools for blind users give inadequate contextual feedback on the state of the drawing, leaving blind users unable to comprehend and successfully produce graphical information. We have investigated a tactile method of drawing used by blind users that mimics drawing with a pencil and a paper. Our study revealed a set of properties that must be incorporated into drawing tools for blind users, including giving feedback for relocating important points, determining angles, and communicating the overall structure of the drawing. We describe a grid-based model that provides these properties in a primitive-based 2D graphics environment, and we introduce its use in drawing and other graphical interactions.
