Nope. GPS isn't anywhere near accurate enough for that- believe me, I've tried. It's usually accurate to a few meters, which is fine for an overhead map, but would be horribly jarring when used for AR.
For what? I remind you that we're talking about a Wikipedia filter. Wikipedia entries are so coarse grained with respect to position that you don't even need GPS-level accuracy. (Not to mention it can correct itself with the help of the built-in maps, e.g assume you walk in the sidewalk and not 4 meters across inside the buildings etc).
"That place is the Brooklyn Bridge, that thing down the road is the Katz delicatessen, further down is CBGB, stuff like that".
Where's the need for "more than a few meters accuracy"? If it can show me info of the nearby stuff (5-10-20 meters away) on my Glasses, it's perfectly good.
It doesn't have to super-impose it when I look at the specific building (that would be stupid anyway, cause it would necessitate me to keep looking straight at the building to see the info).
Indeed. Military applications that require the type of precision in orientation measurements and derivatives that are being discussed here use high-rate precision Inertial Navigation Systems. INS measurements are made in a coordinate system fixed to the platform. All geometry calculations happen in this coordinate system. GPS and other sensors are used to translate positions in the platform coordinate system back to a "real world" system like lat-lon or ECEF.
This is actually a problem I have been thinking about a fair bit for the Rift. I'm not sure what the best way is to solve it in this package size. I'm thinking a first pass will need some sort of off-board reference.
