Being billed as a technology demo and not necessarily something that we’ll see as a practical sale item down the road, Microsoft put their latest invention on-show and while its not something any of us will ever need, it is without a doubt very neat technology. The demo shows how, using a Windows Phone 7 smartphone, Microsoft Kinect and connecting through Xbox Live, a user can take advantage of the interaction provided by games such as Microsoft Rally Ball game. Windows Phone 7 users can toss balls onto the live on-screen play providing the playing character with new, human made targets instead of an all computer feed.
