This is still at the experimental stage. Read more about it motion tracking page.

Tracking Feature with Logitech Quickcam Sphere/Orbit

Motion supports controlling the pan and tilt feature of a Logitech Quickcam Sphere/Orbit.

Motion can move the camera to a fixed position given in degrees pan (left-right) and tilt (down-up). Movement can be set with absolute coordinates or relative to current position. There is also an auto tracking feature for the Logitech Quickcam Sphere/Orbit but it is not very mature. It is fun to play with but not very useful yet. See this topic of how KennethLavrsen controls his Sphere: LogitechSphereControl.

For a detailed description of http remote control see the section Remote Control with http.
