Mouse replacement software that moves the pointer as you move your head. It works on standard PCs equipped with a web camera. No additional hardware is required. Based on the award winning Facial Mouse software. For Linux and Windows systems.
I did not like the program at all. It is apparently aimed at those with problems using a mouse, as indicated by some of the positive reviews. For them, perhaps, it is quite helpful, but I found it absolutely counter-intuitive. I uninstalled it immediately (about five minutes after installation).
