We've seen Kinect do some pretty interesting things these past few weeks, but ironically, the most exciting thing we've seen so far is simply using the camera to control Microsoft's Windows 7.
Here you can see Wolfgang Herfurtner, boss of "multitouch and gesture computing" company Evoluce, use several Windows 7 programs using nothing but his hands. In some, there's even room for two people to stand in front of a screen and each manipulate an object.
Put Windows up on a big screen and get a Kinect at the front of a room and, thanks to the potential for true collaboration (instead of having to wait to share a mouse/pointer/board), the entire dynamic of office workspaces could be changed forever.
That and, you know. The Windows 8 version of Minesweeper could be amazing. Not to mention a game like SimCity, going by the first lot of footage in the clip below. and Pictionary! Oh, the possibilities for Pictionary...
