With a display smaller than a fingernail, the voice-activated device allows users to read email, take photographs and do other activities with minimal use of their hands, similar to a Bluetooth phone earpiece.
A Google rep showing the device said Google Glass is currently available only for app developers and there are only about 1,000 in existence. The price tag is expected to be around $1,500.
Most people won’t be able to get their hands on the technology until 2014; Google chairman Eric Schmidt told BBC Radio last month Google Glass was probably “a yearish away” from being publically available.
