Effect of Movement Velocity and Communication Delay on the Utterance and Recognition of Demonstrative Indicators in Remote Collaborative Work with Shared Visual Perspective

Abstract

In remote collaborative work, since collaborators are not in the same physical space, the referential scope of demonstrative pronouns used to indicate objects may differ between those who are local and those who are remote. However, the dynamics of such references in remote collaborative environments remain underexplored, particularly regarding how an user’s movement velocity influences the scope of these demonstrative indicator. Therefore, this study aims to clarify the referential scope and consensus areas of demonstrative indicators used by local and remote users for objects in a remote collaborative work scenario where both the local and remote users share the same perspective, particularly when the local user is in motion.
