GRAB - Computer Graphics Access for Blind People through a Haptic Virtual Environment

Three-dimensional computer graphics and their applications remain largely inaccessible to blind computer users. Grab enabled blind persons to have access to the three-dimensional computer world through the sense of touch and audio facilities. A new haptic virtual environment will be created. The environment will allow users tomove their fingers (thumb and index) over a virtual object, and recognise its geometric features as if manipulating a real mock-up.
