Wow - Steve Mann - haven't checked what he's doing in ages - real blast from the past :-) I was really disappointed the AR/VR company he was with went under - I had really high hopes for it.

RE: changing you laptop screen. My buddy wants an 'AR for Electronics' that can zoom in on components like a magnifying glass (he wants head mounted), identify components by marking/color/etc and call up schematics on demand. So far, nothing seems to be able to do that basic level of work.
