Re: Cool app that shows comments when you point a phone at a plac
I'll take a longer look at your link tomorrow. I live in a way far different time zone
Basically, the way these apps work, is similar to facial recognizition. The foto gets uploaded, and it uses points of reference to match against a database.
For example, St. Basil's Cathedral near the Kremlin on times square. If you take a full front perfect foto, it will most likely, be able to use reference points, and match it against it's database.
But if you took a foto from a different angle, it's going to have a little difficulty, and as a result, you might get info from a monestary in Sergie Pasat.
As far as "waving the camera around", as the ad depicts........
And as anybody with a mobile knows, you don't move the camera at all, when taking a foto...
