For long the TV viewer has been the stereotype of inactivity, the derisively dismissed “couch potato”. Now he looks set to go places. That is if the things that the boffins at Cupertino and Redmond have conceived of become reality. Apple is believed to be working on a television set for release later this year. And when Apple does things, it shakes things out of the sofa. So you could well have a TV set that responds to your iphone, ipad or even your voice. Which shouldn’t scare the guys at Microsoft, for they are also reported to be finalising the integration of the Kinect motion-gamer with television. The Xbox console will become the hub of your entertainment (it already has services like ESPN, cable and satellite programming on Xbox Live). And with Kinect for Windows likely to support a “seated 10-joint skeletal tracking system”, you can imagine the uses it could be put to for the TV viewer.
