These combinations of technology packaged for consumer use are coming think and fast from E3. (I really must go next year!)
This time using a PSP with a camera and some registration markers to allow the collection and battling of multiple handheld views of individual pokemon style characters.
Now I have Eye of the Beholder an AR card game on the PS3 and the last few blog posts have been about Natal and Eye Pet. However this has a subtle extra point. The representation of a character via the magic window effect off a registration point can be done on anything, what they have done here though is use the connectivity of the PSP to allow more that one point of view or experience to be shared.
I see my view of the Augmented World, you see yours and we interact through it. Sounds like a metaverse to me, once we get from the single user experience (which is very cool but essentially a book or a movie) we then start to get to augmented reality virtual world brokered human communication.
In this example the kids are battling together in the same place, but as everywhere is local and distance does not exist on the web you can extrapolate how this could expand (as with Natal and the other tech) to a mixed mode virtual world or communication channel.
I bumped into this via the Guardian games blog feed on Youtube
