A shape-changing haptic navigation interface for vision impairment.

ABSTRACT: Individuals with visual impairment (VI) require aids such as white canes and guide dogs to navigate their environments. Modern localisation technologies have the capacity to transform the way individuals with VI navigate surroundings, but they have yet to do so. A critical barrier is the inability of human-machine interfaces to communicate precise navigation instructions non-visually. We present a shape changing haptic interface (Shape) that provides spatial guidance in two dimensions via bending of its body. Individuals with VI and sighted individuals were recruited to locate virtual targets in 3D space using Shape and vibration feedback (Vibration), and sighted individuals were also asked to visually locate targets. Throughout, device orientation and position were tracked in real-time us
