This Program allows you to navigate your game by using your own body as a joystick. You can move your body to the left and right to turn in those directions. And to the front and back to go forward or backward.
It's possible to adjust the sensitivity to your circumstances and also possible to enhance the camera input by increasing contrast etc or even use false colors to enhance the recognition.
While developing this program most effort was made to minimize the load on your CPU so that it does not affect the performance of your games. (vJoy joystick emulation is available for free from: https://sourceforge.net/projects/vjoystick/)
