Techcrunch writes about the iPhone 3GS:
Don’t get me wrong, the compass is interesting, but aside from Google Maps and maybe the GPS apps, I really don’t see the point of it. And for the first few days I had no idea how to activate the compass features in Google Maps — you have to tap the location button (in the lower left corner) twice.
Someone please explain to this man the virtues of Augmented Reality.
What you’re seeing here is a iPhone 3GS video-recording an app running on an iPhone 3GS. The app overlays an icon on the screen when the phone is heading “east” (for determined values of East).
Again, just a simple couple of hours tech demo but the possibilities are amazing.
