PhonePoint Pen is an experimental new system for capturing gestures made with a mobile phone. While motion-sensing apps are nothing new, this is the first we have seen that actually lets you write letters in the air that your phone can read and understand.
The project is the work of students at North Carolina’s Duke University. “We’re trying to get past the whole idea of typing on a keyboard or using a stylus to enter information into devices,” said Duke’s Romit Roy Choudhury. The app should in theory work on any smartphone with a motion sensor built in.
