Volumetric Haptic Display
A volumetric haptic display or VHD is an attempt to create a 3D touch environment, for use in a VR or AR simulation. Different to stereohaptic feedback, this method requires an equal physical space to the virtual space being simulated, and projects the feeling of touch into the space.

A comparison. Two women, both with prosthetic limbs. On the left, a standard prosthetic. On the right, a haptic prosthetic giving touch feedback. Who can complete the task faster, and is there much difference?
An interesting little quote from Mona Lisa Overdrive which provides brain fodder to chew on for the future of haptic (touch) interfaces.
One of the severe problems with haptic input devices (other than the very, very basic type that jack directly into the nervous system) is that the mechanics of hand-held systems only bend or push so far, then they hit engineered limits and the feeling dissipates.
In October 2009, iRobot announced that they would be receiving additional funding from the US Robotics Technology Consortium. They plan to use much of this money to add full haptic feedback technology to their heavy-duty robots.
There are several potential ways this display is working. One of the simplest and most plausible is a colour e-paper display behind a completely transparent display medium. The e-paper handles the picture, 'refreshing' the colour display to a matt black when the layer in front, the graphical display is activated. As soon as that deactivates, the 'oil' is re-drawn. Simple, elegant, and still far beyond us.
NASA has unveiled a weather satellite capable of converting any typhoon into a 3D volumetric map in unprecedented detail, in real-time. These maps being extremely useful for both dedicated weather simulators and interactive 3D environments alike.
