Overview: This research reviews the promise and the pitfalls of visual cues in computer-mediated communication (CMC). The first section reviews theories advocating the utility of visual cues in telecommunication. Empirical research consistent with such theories has shown that communicators express preference for multichannel communication, whereas observational results, in contrast, indicate that visual cues often fail to enhance virtual groups' work. The second section extends this paradox by reviewing research that shows when and how visual cues detract from CMC social impressions and evaluations. Alternative uses of visual information, focusing on objects rather than people, show dramatically different effects. Taking into account the persistent preference for multimedia despite its disappointing results, the final section attempts to redirect theories of media selection to include a component about the principle of least effort in media preferences and how visual cues are at the same time easier and inferior to text-based CMC in many settings.
Talking with another individual is still the easiest way to share information, because other people have the ability to see our gestures and facial expressions, listen to our tone of voice and understand what we are trying to communicate.
Microsoft (1999), “Knowledge Workers Without Limits”The epigraph reflects a common presumption that an abundance of nonverbal cues is the easiest way to facilitate shared understanding. In contrast, some of my students' course evaluations reflect our regular face-to-face encounters in class:
