Abstract: Chapanis describes an important empirical study on
        the channels and modes through which people
        converse: voice, handwriting, typewriting, video,
        and their combinations. The results suggest that
        while voice and text gives substantial improvement
        to communication over text alone, adding video gives
        only a minor improvement.
