Microsoft Files Patents for Virtual Game Controller
SmartAboutThings writes "A newly discovered patent shows that Microsoft might be interested in developing virtual controllers for tablets and smartphones. A while ago, it didn't quite make sense why Microsoft would need such a piece of technology, but with the announcement of their Surface tablet, it suddenly takes on a new perspective."
I think a few board games (Catan comes to mind) would be pretty playable on a moderately-sized, shared touch surface, with everyone's phone acting as their hand.
That phrase right there communicates the state of the patent system. Finding out which patents exist take more research and effort than inventing the patentable items.
I'm all for gadgets, but why not just take the Catan board from the shelf and play?
