The process is as follows. iTracker captures our face using the iSight (or another compatible camera), and transforms our head movements into cursor movements.
Sensitivity and speed are configurable through the properties of the application. It also allows us to define a key that allows us to activate or deactivate tracking, and the corresponding movement of the cursor on the screen. It is also possible to program a delay, so that when we leave the cursor stopped for this time, the program generates a mouse click . If we keep the ctrl key pressed it is equivalent to a click with the second mouse button. Another way of clicking, double-clicking and right-clicking would be nice (we can also use these “real” mouse buttons while using the program).
Surprisingly, the program works quite well , especially if you have a big screen, as you will involuntarily move your head a bit following the cursor. Obviously the program is not a substitute for the mouse , but it may be useful for people with physical disabilities.
The program costs $29.95, but you can try it for free.
