Have you heard of ConnectedED? They’re a part of Sony UK, and are a marketing channel for education and training via PlayStation products. To put it simply, they facilitate the use of Sony’s consoles as teaching tools.
Part of this initiative is something called Second Sight, which is an augmented reality system that can be run on the PSP via a peripheral that locks into the camera slot. What this does is, it allows you to embed digital content in print media like magazines that the Second Sight can then detect and play. Not only does it allow for videos, but also for 3D imagery in print that you can look at from different angles by adjusting how you hold your PSP.
Rather than try to explain it, I’m going to point everyone to the video above to check out. While one wonders if it has any real long-term potential as an educational tool — aren’t we eventually going to move to digital textbooks? — the potential use for it in games is very apparent.
