Mutually Shared Gaze in Augmented Video Conference

Augmenting video conference with additional visual cues has been studied to improve remote collaboration. A common setup is a person wearing a head-mounted display (HMD) and camera sharing her view of the workspace with a remote collaborator and getting assistance on a real-world task. While this configuration has been extensively studied, there has been little research on how sharing gaze cues might affect the collaboration. This research investigates how sharing gaze in both directions between a local worker and remote helper affects the collaboration and communication. We developed a prototype system that shares the eye gaze of both users, and conducted a user study. Preliminary results showed that sharing gaze significantly improves the awareness of each other's focus, hence improving collaboration
