Abstract
In one embodiment, a conference with multiple end points is provided. At the locations, multiple screens may be configured to display video from a portion of the multiple end points. Video from multiple locations is output onto the multiple screens, such as video streams from N different segments are output on N different screens. The video output may be determined based on a first dimension of the floor control algorithm. A push-to-talk input may then be received from a button. A video segment associated with the push-to-talk button is then determined and the video segment is output on one of the multiple screens in response to receiving the push-to-talk input. The push-to-talk input may be used by users that cannot actively participate in the first dimension of the floor control algorithm. For example, users using sign language cannot speak louder and thus by using the push to talk button or hand gestures can indicate their desire to be switched in as one of the displayed segments.
