The Google co-founder Sergey Brin recently described touchscreen smartphones as "emasculating". This week, tech fans finally got their first good look at what he plans to replace them with: a US$1500 ($1820) pair of hi-tech spectacles.
At the South by Southwest (SXSW) technology festival in Austin, Texas, Timothy Jordan, Google's senior developer advocate, gave the first detailed demonstration of Google Glass, the hotly anticipated web goggles, which display digital information on a tiny screen just in front of the wearer's right eye.
Mr Brin, 39, who was photographed sporting a pair on the New York subway in January, has suggested the specs are the first in a new generation of "wearable tech" items. He first demonstrated an early iteration of Google Glass in May 2012.
The SXSW presentation is part of a long build-up to the product launch later this year. Early adopters who signed up to be Glass guinea pigs will receive their US$1500 prototype imminently, while consumers should be able to purchase the device before the end of the year.
