Tagging The Real World

Sekai Camera’s basic concept is still intact: Use the iPhone camera to overlay tags and information onto any object in the real world. Users then need to look through the camera to see icons pop up that contain information on buildings, stores, sightseeing spots or objects.

The prototype I tried out today was a bit buggy but worked as promised, showing tags with information (sounds, pictures and text) on other booths installed in the exhibition hall. Many people speculated how Sekai Camera works technically. The answer is simple: The user’s location is identified through GPS (no cell-tower triangulation or image recognition technology is being used). As the iPhone doesn’t have an internal compass, the direction of where the viewfinder is pointed at can’t be measured: Users need to flick fingers left or right to find relevant tags that are around them (as demonstrated in the video I took below). Tap a tag and the information it contains appears in the form of a window.
Pretty cool. The era of augmented reality is here. Check the link below for a video of the Sekai Camera in action.
