Opinion Game theory
With the Kinect sensor,all you have to do to become a part of a game is stand in front and play.

It is a strange feeling. How technology has changed over the years. The first computer game I played,in the mid-1980s,had us link the gaming unit to the TV trough the antenna port,attach a tape recorder to the gaming unit to load the cassettes and then wait about 15 minutes for the game to be loaded before finally starting to play.
Then next computer game I owned was the very popular Japanese Atari,which was very easy to play,but took ages to be tuned into the AV channel of your TV. In those days that was the real cutting edge of technology with a very responsive joy sticks and even a gun which could shoot targets with the player just aiming at the TV. For the record,I never got to hold my gun,for the Customs wouldnt permit a gun-shaped toy even in check-in baggage in the heydays of hijacking.
But all these seem like Stone Age in comparison to the new Kinect for Xbox 360s. With this revolutionary new sensor,all you have to do to become a part of a game is stand in front and play. You no longer have to be vicarious when it comes to physical endeavours,as this new technology will let you play anything from beach volleyball to decathlon in the safe confines of your living room. Along with the fun,the one other thing that is guaranteed is the sweat factor,for there are no short cuts in a Kinect game and you have to toil to win.
A couple of years back we would have thought that this kind of a gaming experience would need a bodysuit with embedded sensors and a room full of trackers to record your body movements. Instead the Kinect sensor is more like a large webcam with multiple cameras and sensors that can track all movements of the player in 3D. And it does a pretty good job of it.
We should have had some idea of what was coming when Nintendo came out with Wii last year. There were people who said this was the death of the Xbox; they had no clue what Microsoft had winding up in its box.
