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.
