Control the mouse pointer with your head movements.
Camera Mouse is a free program that enables you to control the mouse pointer on your computer screen just by moving your head. To use Camera Mouse you need a Windows 7 or Vista or XP computer and a webcam. Camera Mouse was invented at Boston College to help people with disabilities use the computer. We make it available for free download, with no gimmicks or advertisements, because we want to help as many people as possible.
Works fairly well as a normal cursor and basic programs. It's Freeware.
Cons
Does not work with Unreal Engine or Source Engine which is primary used for games and simulation.
Summary
Originally tried the program as a replacement for CamSpace which is essentially the same thing. Although it works well as a basic cursor it does not work with most commercial games or high end programs.
