<p>A video teleconferencing device (100) uses pattern recognition technology and image tracking technology to generate control signals indicative of the relative position of the user's mouth with respect to an audio input device (106). The directionality of the audio input device (106) is altered to compensate for changes in the position of the user's mouth. A self-contained wireless version of the device includes a transmitter and receiver. A desktop version of the device may be wireless or may include a connector to provide a network connection.</p> |
