Abstract

A system provides for controlling a cursor on a screen automatically and dynamically when using a video camera as a pointing device. A computer displays static or dynamic content to a screen. A video camera connected to the computer points at the screen. As the video camera films the screen, frames captured by the video camera are sent to the computer. A target image is displayed by the computer onto the screen and marks the position of the screen cursor of the video camera. Frames captured by the video camera include the target image, and the computer dynamically moves the target image on the screen to ensure that the target image stays in the center of the view of the video camera.
