Between various patents and even a bog-standard Sony Ericsson, we've already thought about the possibilities of gesture-controlled phones. The University of Tokyo, in typical form, has taken it one step forward and released a video showing some sweet Natal-like possibilities.
Recombu likens it to the Project Natal of smartphones, which is a pretty accurate description for the phone pictured in the video, capable of detecting finger gestures by the motion-sensing camera located at the base. While I can't imagine typing out a text message using finger gestures, let alone an email, the idea of scrolling through photos or media is really appealing - and most definitely possible in this day and age.
