'Wearable' Gadgets Respond to Body Movements

Someday, you may be able to tap your fingers to control your DVD player or roll your eyes to pump up your music player’s volume—if technology under development by Japan's top mobile carrier comes to fruition, the AP reports. A cell phone shaped like a large ring that wearers can hear by sticking their fingers in their ears is another of NTT DoCoMo's inventions.

The Japanese wireless leader showed off a sensor-equipped headset that detects eye movements and fast-forwards when users dart their eyes twice to the right. A wristwatch turns wearers’ hands into remote controls for DVDs or other devices by identifying when they tap their fingers. The company could not say when, or if, the technology will be available commercially. (More wearable computers stories.)
