CES 2014: 'Iron Man' reality glasses put to test

Silicon Valley start-up Meta is showing off a prototype of its 3D augmented reality glasses.

With a price tag of $3,000 (£1,827) the Meta Pro allows users to interact with and manipulate a virtual environment in 3D space.

The firm's founder and chief executive, Meron Gribetz, said the glasses represented the next wave of more natural computing. He will put them on show at the Consumer Electronics Show (CES) in Las Vegas on Tuesday.

The BBC's North America technology correspondent Richard Taylor was given an early demo ahead of the event.
