Abstract
A position determination module is described which receives image information from a video camera. The position determination module identifies at least one reference field in the image information to provide identified reference information. The position determination module then generates position information based on the identified reference information. The position information is associated with a position of the reference field with respect the video camera. In one implementation, the video camera is stationary and the reference field is coupled to a user-manipulated device. In another implementation, the reference field is coupled to a stationary display device and the video camera is coupled to a movable user-manipulated device.
