The iPhone gets augmented reality vision.|
By combining a smartphone's camera, GPS, and net connection Sekai allows social tagging, or "Air Tagging" as Tonchidot describes it, of the real world through the mobile screen. Yeah, that's just crazy. Wait for the headset VR-sunglasses model.
Using the phone's built-in GPS, Sekai calculates your position. The viewfinder for the camera then displays location-specific information graphically on top of your real-world view.
