The demo video shows someone scrolling by waving two fingers in the air (mimicking the standard OS X trackpad gesture), snapping fingers to start iTunes playing, rotating a fist to increase the volume, holding up a hand in a 'stop' motion to pause a video, gesturing backwards to rewind a video and snapping fingers to play the video. The demo also illustrates a variety of other uses for the device, from delivering a presentation to controlling a remotely-operated vehicle.
Unlike Microsoft Kinect, no camera is required, but the armband approach means it will work only with gestures made with one hand rather than detecting whole-body movements.
Very cool and impressive. I hope this finds its way into our future soon - Steve Wozniak
