Engineers at Duke have developed a new way to enter information using smart phones: by writing it into the air. They've leveraged the phone's accelerometers (an internal device that tracks the phones movements and orientations, a huge asset in most games) and turned the phone into a pen, and the air into a blank tablet.
"By holding the phone like a pen, you can write short messages or draw simple diagrams in the air," said Sandip Agrawal, an electrical and computer engineering student at Duke University in North Carolina.
The PhonePoint Pen is due out in a few months, and could be the safe alternative to "driving while texting" the world has been waiting for.
