"Why don’t butterflies fly in straight lines?" and "Is the right side of your brain really more creative?" BBC Click Radio presenter Gareth Mitchell answers life's big questions
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?
