Visual Information as a Conversational Resource in Collaborative Physical Tasks 论文

摘要

In this article we consider the ways in which visual information is used as a conversational resource in the accomplishment of collaborative physical tasks. We focus on the role of visual information in maintaining task awareness and in achieving mutual understanding in conversation. We first describe the theoretical framework we use to analyze the role of visual information in physical collaboration. Then, we present two experiments that vary the amount and quality of the visual information available to participants during a collaborative bicycle repair task. We examine the effects of this visual information on performance and on conversational strategies. We conclude with a general discussion of how situational awareness and conversational grounding are achieved in collaborative repair and with some design considerations for systems to support remote collaborative repair.
