Call for Papers

We invite you to submit your unpublished work to the Workshop on Collective States in Multimodal Interaction, to be helf in conjunction with the 28th ACM International Conference on Multimodal Interaction (ICMI 2026) in Napoli, Italy. The workshop will take place on Oct 9th 2026. Accepted papers will be presented at the workshop.

Understanding collective states in group interaction is an emerging challenge at the intersection of mulitmodal AI, communication science, and social signal processing. While a large body or prior work has focused on individuals or dyads, many real-world settings, such as meetings, brainstorming sessions, and collaborative human-AI teams, depend on group-level phenomena such as collective engagement, shared attention, group affect, rapport, cohesion, and coordination. Recent progress in multimodal sensing and agentic AI creates new opportunities to model how these collective states arise, evolve, and influence individual behavior within groups.

This workshop focuses on multi-party intersection settings in which AI systems must not only sense individuals, but also understnad emergent group dynamics and, potentially, support them as peers or facilitators. The goal is to bring together researchers across artificial intelligence, multimodal interaction, and organization and communication science to advance methods, benchmarks, and applications for sensing and reasoning about collective states.

Topics of interest include, but not limited to:

  • Multimodal sensing and modeling of collective states in group interaction
  • Group-level phenomena such as collective engagement, shared attention, group affect, rapport, cohesion, and coordination
  • Links between individual participant states and emergent group dynamics
  • Audio, video, language, physiological, and behavioral cues for multiparty interaction analysis
  • Multimodal fusion and temporal modeling for group behavior understanding
  • Annotation schemes, datasets, and benchmarks for collective states
  • AI agents as peers or facilitators in human-AI hybrid teams
  • Adaptive systems for improving participation, coordination, brainstorming, and collaboration
  • Explainability, robustness, fairness, privacy, and ethics in group sensing
  • Applications in meetings, education, healthcare, robotics, organizational settings, and other collaborative environments

We invite authors to submit papers in accordance with the ICMI formats and guidelines. Submissions will undergo peer review by the workshop program committee. The review process will be double-blind. Further information about formatting, submission instructions, and presentation format will be announced on the workshop website.
