Let me explain what I mean by lack of data: 1. If you do WiFi positioning, you need several fingerprints (i.e. lists of access points) in order to get enough information (and accurracy): Who's going to stumble that for whole public buildings and cities? (I'm going to launch a crowd sourcing approach with my IndoorWPS).
2. Picture database: I've experimented with image recognition similar to www.kooaba.com: That needs lots of pictures and technology is far away from consumer market. 3. Existing data like OpenStreetMap or Wikipedia (see www.mobilizy.com/wikitude.php) don't have yet really compelling data for AR. -S. P.S. Here's another app with an AR Identity idea: http://bit.ly/ZbZYO - quite frightening to some more privacy oriented people. 2009/8/12 Tom Longson (nym) <[email protected]>: > I don't agree with the lack of data argument.
