Tangible display makes 3D images touchable

3D with feel will require new UI paradigms ...

"A system that makes three dimensional images solid enough to grasp has been unveiled by Japanese firm NTT. It could let businesspeople shake hands from across the globe or allow museum visitors to feel precious exhibits that are normally out of reach, the company says.

The prototype Tangible 3D system combines a 3D display with a "haptic glove". The display creates lifelike images appear in just in front of a flat screen. It creates the illusion of depth by showing slightly different images to each of the viewer's eyes. This means no special glasses are needed.

Attached to the display is a haptic glove. Once inside, a user's hand is touched by numerous force-feedback components to make it feel as if it interacting with something solid.

The system can also translate real-world objects into virtual representations. Two cameras image the items in 3D so that they can be displayed on the screen. A connected computer then processes the 3D image to generate a tactile representation of the object.

This set up means that if the object being filmed is moved, the three-dimensional image also moves in real-time and the user will feel the movement with their hand."    (Continued via New Scientist)    [Usability Resources]
