Sharing Gaze for Remote Instruction

Abstract

In this paper, we report on how sharing gaze cues can assist remote instruction. A person wearing a head-mounted display and camera can share his or her view with a remote collaborator and get assistance on completing a real-world task. This configuration has been extensively studied in the past, but there has been little research on how the addition of sharing gaze cues might affect the collaboration. This paper reports on a user study exploring how sharing the gaze of a remote expert affects the quality of collaboration over a head-worn video conferencing link. The results showed that the users performed faster when the local workers were aware of their remote collaborator's gaze, and the remote experts were in favour of shared gaze cues because of the ease-of-use and improved communication.
