Researchers at the University of Tokyo have created an advanced motion-tracking camera that is designed to attach to a mobile device like a cell phone. It allows for “in-air typing” or Project Natal-style gestures to type out text messages or emails by detecting finger movement. The demo above shows how something like this could replace a physical and touch (virtual) keyboard on mobile devices.
Finally, the Nintendo DSi’s camera is being put to exciting use. An upcoming Japanese-only game called Rittai Kakushi e Attakoreda will utilize the DSi’s (inner) camera and motion tracking software to follow your eyes and create a 3D illusion that you are looking behind or in front of certain objects in the virtual world. The tech being used here is not so different from Johnny Chung Lee’s Wii head-tracking experiments. Watch the demo above and it’ll all make sense. Magical, isn’t it?
