We’ve just been given the full details on the Vuzix 920AVs that I posted about on Friday, and gosh, they look more exciting than I had anticipated. Remember how I said that they seemed to be the non-interactive version? They’re not – there’s an option to fit them with a “6-Degree of Freedom tracking sensor and/or Stereo Camera Pair”.

That means that you can mix images from in front of you with virtual content. Imagine looking down a street, and seeing little markers come up from famous buildings saying what they are, or the ultimate Sat-Nav system which can tell which way you’re looking and show you which way to go with a line on the road.
