Have you ever needed to write a message but just couldn’t, because your hands were too occupied, or you were driving? Two Duke University scientists (Ionut Constandache and Sandip Agrawal) have developed a piece of software that makes use of the phone’s accelerometers (it’s probably an iPhone) to let you just draw the letters in the air with the phone and write your text message.
Neat, isn’t it? Still, I don’t think this will work in an accelerating car, unless they filter out that information, too (it has to be on the 2-dimensional vertical scale).
