In the video above you can see a demonstration of augmented reality on the PSP by use of the PSP camera and the “Second Sight” technology which allows tags embedded in textbooks or magazines to cue relevant audio or video clips directly on the PSP.
Makes me curious as to how much memory is required. If every tag causes the PSP to download some sort of file to play does it auto delete it after it is done being played? Does it require a wireless internet connection to download the data from? The technology is quite interesting and this is only the beginning.
