American research students have invented a smart watch which can be controlled by your breath. Researchers at Georgia Institute of Technology in the US created Whoosh, a technique that allows a person to control the watch by blowing, exhaling, shushing, sipping or puffing on the screen.
A wearer can shush the watch to ignore a call or blow on it twice to accept. The watch can also be locked or unlocked using a correct combination of short or long breath. The technology could have potential for people with disabilities.
