Cameras that work (Verified)
The following cameras have been personally verified to work by Freelook's author. If you are looking at other cameras, then the most important features to look for are framerate at 160x120 (above 30 is good), and ability to disable auto-exposure/gain.
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. Freelook is similar in execution to the excellent cam2pan and TrackIR systems, although unlike the latter, Freelook only requires a cheap off-the-shelf webcam.
