Issues in surgery can be related to collaboration problems such as miscommunication and misunderstanding. Analysis of these collaborative situations can be done by experts, but it is a long and complex process. Moreover, this approach does not allow for real-time analysis and feedback on the collaboration. Some recent approaches aim to assess and model the quality of collaboration using measures that can be computed in real-time (e.g., non-verbal, gaze, physiological data). Considering some of the challenges related to the evaluation and modeling of collaboration, we are working on a tool that aims to compute metrics in real-time to report on the quality of collaboration within a group. This would allow us to act before a critical situation emerges. We first apply this tool to a collaboration situation in a virtual environment to test their effectiveness and their effects on the situation before applying them in a real situation as surgery.
