xstroke

Fullscreen gesture recognition

xstroke is a full-screen gesture recognition program written for the X Window System. It captures gestures that are performed with a pointer device, (such as a mouse, a stylus, or a pen/tablet), recognizes the gestures and performs actions based on the gestures. xstroke is most commonly configured to "type" characters in response to gestures, but it can also emulate mouse button "clicks", launch programs, and other fun things.
