Freelook allows you to use movements of your head to accurately control your mouse cursor. This translates to hands-free viewpoint control in games such as IL2 Sturmovik and Lock On: Modern Air Combat, as well as providing a mouse alternative for handicapped users. It is similar in execution to the excellent cam2pan and TrackIR systems, although unlike the latter, this only requires a cheap off-the-shelf webcam.

Freelook accomplishes this by tracking the position of a visible marker, which may be as simple as a square of white paper attached to the brim of a cap, or for better performance in unusual lighting situations, an LED may attached in a similar fashion.
