This paper proposes an integrated setup for a multi-scale asymmetric collaboration scenario, specifically designed for a remote-expert use case. The system centers on the expert side, giving the remote expert an exocentric view of the shared workspace, which is a common approach for providing a broader perspective than local participants have.
The core contribution is the evaluation of avatar gaze control in this setting. By representing the remote expert as an avatar in the tabletop mixed-reality environment, the system aims to let the expert guide local users through gaze cues. The paper focuses on how well this gaze control works when the expert is spatially removed from the physical tabletop.
Because the abstract is truncated, details about the evaluation method and results are not available in the source. The significance lies in addressing the expert's viewpoint in asymmetric collaboration, where the remote and local users have different scales and perspectives. This work appears to target a practical gap in remote assistance for tabletop tasks, though the full findings remain unspecified in the provided text.
