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 type of physical haptic feedback. Disney took on this research because they believed that technology is advancing towards more virtual or augmented reality applications. According to Disney, the missing piece in this emerging computer-augmented world is the absence of physical feeling of virtual objects. Disney's main intention for this research was to encourage other research regarding new applications of non-contact haptic feedback. In 2013, Microsoft explored the same area as Disney. They used air vortex rings in order to try and provide haptic feedback for an at-a-distance interaction. Microsoft mostly focused on the study of vortex formation theory and parameters
