A videoconferencing system (10) includes a touch screen display device (200) and a videoconferencing unit (100). The display device (200) displays video data for the videoconference and generates touch data based on user selections relative to the touch screen. The videoconferencing unit (100) is operatively coupled to the touch screen device (200) by a video connection and a data interface connection, for example. The unit (100) establishes and conducts a videoconference with one or more endpoints via a network. The unit (100) sends video data to the display device (200) and receives touch data from the device (200). The received touch data is used to control operation of the videoconferencing system (10). The received touch data can be used to initiate a videoconference call, change an operating parameter, change orientation of a camera, initiate a picture-in-picture display, access a menu, access memory, change a source of video data, initiate a whiteboard display, and access a screen of a connected device. |
