Control your computer by making gestures in front of your webcam! You can simulate mouse movements, the keyboard cursor keys, or control the GiMeSpace virtual desktop manangers.
This program allows you to control your computer by making movements with a flat hand in front of your webcam. There are 3 gestures:

- move in horizontal direction while your hand is vertical.
- move in vertical direction while your hand is horizontal.
- move in horizontal direction with 2 hands making a 'zooming' gesture.

To control a GiMeSpace virtual desktop manager, you need to use one that is capable of this. These are the minimum versions that support this:

GiMeSpace Free Edition version 1.2.0
GiMeSpace Desktop Extender version 2.3.0
GiMeSpace Ultimate Taskbar version 2.3.0
GiMeSpace Desktop Extender 3D version 3.1.0

These programs can be download from http://gimespace.com

You can adjust the sensitivity and the scroll/movement speeds by adjusting the trackbars. You will need to experiment a bit to find the ideal settings.
While developing this program most effort was made to minimize the load on your cpu so that it can even be run on low powered netbooks and does not affect other programs that much.
