Spatial Haptic Orientation for Visually Impaired People

Is it possible to show space relations to blind people ? Techniques and experiments described in this article explore several ways of accessing spatial information by blind people using one point forcefeedback device. The study focuses on two techniques supporting an orientation in buildings. Preliminary results show that a wider spectrum of different techniques suitable for blind people is needed.
