When they go on sale later this year, Vuzix's M100 Smart Glasses will be the first in a new breed of hands-free headsets. Similar to Google's much-talked-about Project Glass, the M100 features a display that superimposes images and information onto the user's view of the real world.
As well as the display, the headset also features accelerometers, gyroscopes and a compass for head tracking, as well as GPS for Sat-Nav and a 720p camera for recording video. This means that it could remind you to buy that loaf of bread when you pass a supermarket, flash up a route when you're lost in the Lake District, or even populate the streets with characters from a virtual world.
So would you wear these smart glasses, or are they a step too far in our efforts to merge the real and the cyber worlds?
