In one implementation, a conference bridge or a multipoint conference unit (MCU) receives media streams from the endpoints in the conference. The media stream may contain at least one of audio, video, file sharing, or collaboration data. The MCU measures a characteristic in each of a plurality of media streams and calculates statistics based on the individual participation levels of the endpoints. A dynamic participation indicator displayed at the endpoints shows the relative participation levels of the endpoints. For example, the dynamic participation indicator may show the names of the users in a font that changes size and/or location as the participation level changes. In another example, the dynamic participation indicator may show respective videos of the endpoints in a format and/or size that changes as the participation level changes.
