In the movie "Minority Report," Tom Cruise's character manipulates virtual documents and zooms through images with a flurry of hand gestures and motions. The movie is set in 2054.

But a number of companies already are creating products that mimic that experience, enabling people to interact with monitors and computers using a wave of their hand or a shift in their body position. Think of it as the next step after the Nintendo Wii - only you are the Wii controller.

The trend was on full display at the Consumer Electronics Show in Las Vegas, where the focus has shifted to more natural interfaces for computing and entertainment experiences. Gesture-based controls take the idea to the next step, beyond voice activation, touch screens and motion-sensing via Wii controllers.

The story is too old to be commented.
