Face-to-face and video-mediated communication: A comparison of dialogue structure and task performance.

TLDR

This article examined communication and task performance in face‑to‑face, copresent, and video‑mediated communication (VMC). Study 1 found that audio‑only conversations were longer and relied on verbal feedback that visual cues provide, while Study 2 showed that high‑quality VMC did not match face‑to‑face interaction, with novelty, attenuation, and remoteness likely influencing the differences.

Abstract

This article examined communication and task performance in face-to-face, copresent, and video-mediated communication (VMC). Study 1 showed that when participants in a collaborative problem-solving task could both see and hear each other, the structure of their dialogues differed compared with dialogues obtained when they only heard each other. The audio-only conversations had more words, and these extra utterances often provided and elicited verbal feedback functions, which visual signals can deliver when available. Study 2, however, showed that high-quality VMC did not appear to deliver the same benefits as face-to-face, copresent interaction. It appears that novelty, attenuation, and remoteness all may have contributed to the effects found factors that should be considered by designers of remote video-conferencing systems.
