I”m really surprised that no-one’s talking up the accessibility benefits of something like this. Imagine a version for blind users that dumped the screen in favour of a headset and mic. A little voice recognition and your glasses could tell you where you are, what you’re facing, and even do basic hazard avoidance. That sounds invaluable.

Actually, it sounds like the 90s kids show Knightmare :) http://www.youtube.com/watch?v=ciIfcYwI6Ps
