Google Glass style HMD displays floating interface

A head-mounted display (HMD) that gives the illusion of a control interface floating in mid-air has joined the growing ranks of wearable computers. Researchers at Taiwan's Industrial Technology Research Institute (ITRI) combined a Google Glass type headset with a depth camera to create Air Touch. The interface is projected onto the lens of the glasses and the camera records a user's hand movements.

The current prototype allows the wearer to sketch or dial phone numbers but researchers say this is “just the beginning” of the device’s potential functionality.

They hope to commercialise the product within two years and expect the initial cost of the unit to be $500.
