Microsoft has teased the press crowd at its Mobile World Congress press conference with a demo of the Windows Phone 7 operating system working with its motion sensing controller: Microsoft Kinect.

In what was billed as a technical preview, attendees were treated to a video of a possible future scenario, that saw one player playing Kinect and a second person controlling elements on the screen using a dedicated app that connects to the console.

In this case Microsoft used Kinect Adventures to show one player stopping balls flying towards them and a second player throwing those balls.

The phone will also be able to see people's skeleton on the screen as Kinect maps their movements in real time. 

Microsoft has said that the new feature will be part of a new update that is due “sometime in 2011”, that will be free for all Windows Phone 7 users out there at the moment.

With Nokia promising devices by the end of the year, and Microsoft celebrating its first anniversary, we expect that update to roll out sometime around October if not sooner.
