[PhilNote: We've seen all the elements before, but they've done a good job putting them together into a telepresence device.]
The Haptoclone, created by haptic researchers from the University of Tokyo's Department of Complexity Science and Engineering, consists of two boxes, one containing an object and the other displaying a hologram of it.
When a human hand comes into "contact" with the 3D image in the second box, the hologram emits ultrasonic radiation pressure, making the user feel they are actually touching the object. Meanwhile, special aerial imaging panels act like a kind of mirror, making a hologram of the hand appear visually in the other box, too, so it can "interact" with the original object.
