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 memory opposed to verbal or semantic aspects. Haptic abilities develop in stages in infants: The last two decades have allowed researchers to study the sensory system of infants which gives an insight to the initial stages of thinking, deciding and reasoning in a human brain. Evidence of haptic memory was discovered in infants as young as two months by Myriam Lhote and Arlette Streti, who demonstrated that haptic habituation occurs asymmetrically between the hands of infants, and that differences in haptic memory exist between sexes. For instance, in 2-month-old infants, haptic habituation was found in both the right and the left
