Yes, Microsoft Surface can’t be installed anywhere due to cost and size. So Microsoft Research are coming up with an alternative solution.
To make things short, it’s a combination of a projector and a camera. Not the first to come up with this concept (Light Blue Optics was there first and this is almost identical to that), but it’s nice to know that Microsoft is researching things and expanding their interests.
I’m still waiting for their Screen Concept to be out in the market.
