Opinion: Gesture-based interfaces are out of control

TVs, tablets, phones, cars that enable you to control them by waiving, pointing and generally moving your hands in the air were all demoed at last week’s CES in Las Vegas. As Microsoft proved with Kinect for Xbox 360 (above) gesture control is a wonderful interface that really works. But there’s one problem, possibly a fatal one for the acceptance of gesture control: There are no standard gestures.

Every new gesture-control device makes you learn a whole new “vocabulary” of hand motions.


The new world of gesture control

The number of companies offering the technology is extensive and growing:

Samsung at CES announced new TV sets with built-in cameras and microphones, as well as an in-air gesture and voice control system called Smart Interaction. Another company called PointGrab, which has been making gesture control interfaces for Samsung TVs, announced a new version at the show.
