Gesture-controlled TV

The remote control has relieved generations of couch potatoes from the hassle of getting up to change channels, but is there an even easier way? Toshiba and Hitachi both showed prototype gesture-controlled TVs at CES. A small infrared camera watches the viewer's hand movements and translates them into action. Wave at your TV to switch it on, control the volume with circular motions or navigate a large number of video files in three dimensions with your hands. Look for it in TVs in the next two to three years.

Sony Cybershot G3

Sony's latest Wi-Fi-equipped Cybershot camera, the G3, now packs a Web browser. That means users can upload images and video from the camera directly to Web sites, so long as they are near a Wi-Fi connection. The camera has 4GB of built-in memory, a 10.1-megapixel image sensor and a 4X-optical zoom. Sony has teamed with sites including Shutterfly, Picasa and YouTube on its Easy Upload service. Like all Sony cameras it uses MemoryStick media cards. It is available now in the U.S. for $500.
