From the developer:
HandWAVE tracks your hand and watches for gestures. It is designed to run in the background and is very smart about filtering out unintended movements so that gestures are never accidentally triggered. You can swipe in four directions, perform circles leftwards or rightwards, tilt your hand or make a fist. It provides a powerful but intuitive configuration window that allows you to fully customize which commands are triggered by your gestures.
