Air-Writing with Mobile Phones

Engineers at Duke University are developing a new way to enter information into mobile devices. Rather than typing on a keyboard, they have created a way to “air-write” short notes. Using a phone’s  built-in accelerometer, their application registers a user’s mid-air writing and translates the gestures into text on screen. There are still details to be worked out so that the application functions smoothly, and it’s questionable how useful it may be,  but it’s at the very least an interesting concept.
