Hand Gestures Replace Buttons in Tech

                             Hand Gestures

Tracy Staedter, Discovery News-It won’t be long now before all electronic devices go “nano,” and shrink to the size of frosted mini wheat square. You won’t know whether to turn it on or eat it. But the real question is: How do you press those teeny buttons?

One group of researchers wants to do away with the keyboard altogether. They’ve designed a wristwatch that recognizes hand gestures and uses them for touch-free control of electronic devices such as MP3 players, cell phones, and home appliances. The technology could also be used by a doctor to control a medical device during an operation.

The Gesture Watch has five infrared sensors, four of which sense any hand motion that occurs above the watch. For example, if the user is wearing the watch on his left hand, he can move his right hand over the watch in an up or down, left or right, or circular motion. Different combinations of these movements communicate an action to the watch.

For example, sweeping the right hand once over the watch may mean “power on” a clockwise circular motion may mean “shuffle” and pausing the hand over the watch may mean, “power down.”

It was like we were changing everything with our technologies, but now it seems technologies are changing our life completely….
