AI Summary

This study addresses the challenge of modeling group collaboration behavior in mixed reality (MR). We propose the first multimodal group behavioral analysis framework leveraging passive sensing from MR headsets. Methodologically, it integrates speech dialogue detection, joint attention modeling, and spatial proximity analysis to identify three collaborative patterns—cohesive, fragmented, and competitive—and uniquely combines sociometric principles with graph neural networks to generate quantified social network representations of group dynamics. Key contributions include: (1) the first non-intrusive, multi-sensor-driven automatic classification of group interaction patterns in MR; and (2) the discovery that social structural features are decoupled from task performance yet dominate collaborative experience quality. Evaluated in a user study with 48 participants across 12 groups, our framework achieves high pattern recognition accuracy, delivering a deployable behavioral insight engine for adaptive MR collaboration systems.

Abstract

Understanding group behavior is crucial for enhancing collaboration and productivity in mixed reality (MR). This paper introduces a framework for group behavior analysis in MR, or GroupBeaMR for short for analyzing group behavior in MR. GroupBeaMR leverages MR headsets' sensors to analyze group behavior through conversation, shared attention, and proximity, identifying cohesive, fragmented, and competitive interaction patterns. Using social network analysis, GroupBeaMR provides quantitative assessments of group dynamics, offering insights into collaboration structures. A user study with 48 participants across 12 groups validates the framework's ability to distinguish interaction patterns in MR environments. Our analyses show that group behavior is independent of task performance, emphasizing the significance of social interaction patterns. Our group-type assignments indicate that sensor-based assessments in MR can provide meaningful insights into collaborative experiences, supporting the design of systems that adapt and optimize group behaviors.
