Last weekend I was sharing with my colleagues some videos I saw of the Microsoft Sphere device.
Its much like the Surface device, in that its multi-touch. Unlike the surface its rounded which makes the mind boggle. Clearly it has some sort of central projection and I would imagine infra-red cameras like the surface but this really takes the physics to another level.
So, too does it change the way one might interact with technology. A sphere would not only be good for classrooms but I could see airport information booths and trading room floors benefiting from this.
Anyway here are a few of the videos:
