Volumetric Haptic Display Volumetric Haptic Display A Volumetric Haptic Display (VHD) is similar to a (visual) Volumetric Display, but informs touch instead of vision. A VHD projects a touch-based representation of a surface onto a 3D volumetric space. Users can feel the projected surface(s), usually with their hands. The display is otherwise not detectable, and offers no visual feedback. There are no known instances of a fully operational VHD at this time. The University of Bristol has developed a method for haptic feedback that could be integrated into a volumetric display. The system uses focused ultrasound to create a haptic objet in mid
Haptic technology a Boston University paper published in "The Lancet", "Noise-based devices, such as randomly vibrating insoles, could also ameliorate age-related impairments in balance control." If effective, affordable haptic insoles were available, perhaps many injuries from falls in old age or due to illness-related balance-impairment could be avoided. In February 2013, an inventor in the United States built a "spider-sense" bodysuit, equipped with ultrasonic sensors and haptic feedback systems, which alerts the wearer of incoming threats; allowing them to respond to attackers even when blindfolded. During a laparoscopic surgery the video camera becomes a surgeon's eyes, since the surgeon uses the image
