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 hand. Babies were able to encode haptically some characteristics or features of objects without visual control with their left hand as well as with their right hand. In the experiment, haptic habitutation was formed through an occurred stimuli and at the end, it has seen that even though stimuli was not present, infants still carry on their stimuli habit. It was also shown that infantile haptic memory is robust in that it is somewhat resistant to delays (especially in males). These findings support earlier results by Catherwood, which stated that 8-month-old infants were able to recognize a familiar shape after
