Hand Gestures And Body Poses Control Devices

Computers can now detect and understand body poses and gestures of several people at once, thanks to indefatigable robotics researchers at Carnegie Mellon Universityís Robotics Institute.

The ability to recognize finger or hand poses, for instance, will make it possible for people to interact with computers in new and more natural ways, such as simply pointing at things.

That will also allow robots to perceive youíre doing, what moods youíre in, and whether you can be interrupted, for example. Your self-driving car could get an early warning that a pedestrian is about to step into the street by monitoring your body language. The technology could also be used for behavioral diagnosis and rehabilitation for conditions such as autism, dyslexia, and depression, the researchers say.

This new method was developed at CMUís NSF-funded Panoptic Studio, a two-story dome embedded with 500 video cameras, but the researchers can now do the same thing with a single camera and laptop computer.

One of science fiction's greatest and most original authors, Philip K. Dick, described this very idea in his 1955 novel Solar Lottery:

"You're wrong, honey," Al said seriously. "The l-channel is for news and factual information. The s-channel is for pleasure. I enjoy watching this way, but - He waved his hand and the circuit switched abruptly.

Fans of Douglas Adams may recall his description of gesture-controlled device in his 1979 classic The Hitchhiker's Guide to the Galaxy.
