Existing and emerging haptic technologies offer methods for non-visually rendering and interacting with 2D and 3D graphical information. These technologies include force feedback devices, touch surfaces with vibrotactile feedback, wearable vibrotactiles, and touch surfaces with electrostatic feedback. In this paper we will focus on approaches to non-visual access to 3D shapes. The interactive models focus on two approaches: simulation of 3D shape and perspective on a 2D touch surface; and interactive exploration of 3D shapes using physical motion in a virtual 3D space with either a force feedback controller or wearable haptics. The technologies will be reviewed along with suitability for their use by students with visual impairments. Methodology and results from an ongoing series of exploratory usability studies will be discussed. Benefits and limitations of the technologies and recommendations for further research will be presented.
