Methods, systems or apparatus and computer program products are provided that control the operation of a camera in a video conferencing system. In particular, the setup and display of video information in a video conferencing system may be controlled by displaying a graphic user interface associated with the setup of the video conferencing system which includes an icon corresponding to input from a pointing device so as to provide computer generated visual feedback as to a screen location corresponding to a location of the pointing device and displaying video information so as to replace substantially all of the displayed graphic user interface including the icon. When displaying video information, control of the video information displayed is based upon user input from a pointing device without displaying an icon corresponding to the pointing device. Furthermore, the camera movement may be controlled in real time based on pointing device input such as movement. |
