Just when you thought the DS brought about a whole new level of interactivity, along comes students from Georgia Tech who developed an audio analysis program that allows you to blow at your computer in order to control it. All you need is a single microphone, perform a fast calibration and you’re good to go.
This is a way to support blowing at a laptop or computer screen to directly control certain interactive applications. Localization estimates are produced in real-time to determine where on the screen the person is blowing. You can do this by using a single microphone, such as those that are already embedded in a standard laptop or one placed near a computer monitor by using audio fingerprinting.
You had better have a screen cleaner handy after each use since there’ll be germs and all sorts of nasties crawling all over the place once you’re done with this interface.
