The phone does everything else nowadays, so why not become a pen too? Research students at Duke University are currently working on an app (phone application) that will utilize the phone’s accelerometer to determine spatial positioning which will allow the phone wielder to “air write” and have the text show up on the phone’s screen.
At this stage, the app does not recognize cursive, and the writer must pause between letters. But as with all things, you can expect it to get better and better as the version number starts going up. The user will hold the phone like a pen with one of the corners being designated as the tip of the pen, and the user will then simply write. One idea the app developers would like to see in the future is the ability for the phone to take a picture, then flip to pen mode so the phone could write a note on the photo before storing or sending. You can expect to see the app released before the end of the year.
