In conjunction with ACII 2019, Cambridge UK
Emotions and Emergent States in Groups
@ACII'19, Cambridge, UK - September 3, 2019

The study of affect in groups, although a major goal of affective computing, has received relatively less attention compared to modeling individual affect. This is primarily because studying affect in an interactive, multiparty setting is more complex, and often, not very well defined outside specific applications. Moreover, affective computing has yet not addressed group affective dynamics as a potential driver of emergent states. These include pivotal group phenomena such as trust, conflict, and cohesion, and evolve over time as group members explicitly and implicitly interact to coordinate their actions and achieve objectives. This workshop will provide a unique occasion to gather researchers and practitioners working on approaches for sensing, analyzing, and modeling group emotion and emergent states from a multidisciplinary perspective, including psychological, ethnological, sociological, pedagogical, and computational viewpoints.


Possible topics include:

  • Theoretical approaches to affective dynamics and resulting emergent states in groups
  • Research design: from controlled lab settings to groups in the wild
  • Data collection, annotation, and sharing
  • Approaches for analyzing and modeling groups taking into account emergent states and/or emotions
  • Integration of artificial agents (robots, virtual characters) in the group life by leveraging its affective loop: interaction paradigms, strategies, modalities, adaptation
  • Collaborative affective interfaces (e.g., for inclusion, for education, for games and entertainment)
  • Submission deadline: June 17, 2019 (midnight PST)
  • Submission deadline EXTENDED: June 24, 2019 (midnight PST)
  • Notification deadline: July 7, 2019
  • Camera-ready deadline: July 19 (extended), 2019
  • Date of workshop: September 3, 2019

Submissions should be in the form of long papers (7 pages; 6 pages + 1 page for references) or poster papers (4 pages; 3 pages + 1 page for references). Submissions should follow the paper format for the ACII conference, details here: The reviewing process for the workshop will be “double blind”: the submitted version of the paper should be appropriately anonymized not to reveal either the authors’ identities or institutions.

All submissions will be reviewed by at least 2 experts from our international program committee. Accepted papers will be indexed in IEEE Xplore. Exploration of a special issue from the workshop is underway.

Submissions should be made to the following easychair site:
