About the workshop
LaugHSMI (Laughter, Humour, Smiles in Multimodal Interactions) is a workshop dedicated to advancing research on the role of laughter, smiles, and humor in human-computer interaction and multimodal communication. These phenomena are fundamental aspects of human social interaction, yet they remain challenging to detect, interpret, and generate in computational systems.
Laughter and smiling serve multiple communicative functions beyond expressing amusementâthey facilitate social bonding, regulate conversation flow, signal understanding, and convey complex emotional states. Humor adds another layer of complexity, involving cognitive, linguistic, and cultural dimensions. Understanding and modeling these phenomena is crucial for creating more natural, engaging, and socially intelligent interactive systems.
This workshop brings together researchers from affective computing, natural language processing, computer vision, speech processing, human-computer interaction, and social signal processing to address the unique challenges posed by laughter, smiles, and humor in multimodal interactions. We aim to foster interdisciplinary dialogue and advance the state-of-the-art in detecting, analyzing, and generating these important social signals.

âSemantics and Pragmatics of Laughter: adult interaction, development and neurodiversityâ
Laughter is pervasive in human language use, yet its semantic and pragmatic status remains insufficiently understood. While often treated as a purely affective or paralinguistic signal, laughter systematically contributes to meaning construction both as a stand-alone utterance and in interaction with speech. I will review empirical data and theories leading to the development of an account of laughter as a context-sensitive signal that contributes to meaning both independently and in interaction with speech. I argue that laughter encodes the ascription of incongruity and affective stance, and modulates utterance interpretation in ways that support pragmatic inference (e.g. irony, mitigation, affiliation). Drawing on interactional, clinical and developmental data, I will show that laughter exhibits increasing pragmatic flexibility over time, being informative about childrenâs cognitive and linguistic development. More broadly, laughter demonstrates how non-verbal signals contribute to both meaning construction and conversation management, highlighting the need to extend dialogue semantics and pragmatics beyond verbal language to multimodal resources, with implications for the modelling and design of embodied conversational agents.
Chiara Mazzocconi is a researcher in language and developmental science at Aix-Marseille University. Originally trained as a Speech and Language Therapist, she subsequently obtained an MSc in Neuroscience, Language and Communication from University College London and a PhD in Language Sciences from UniversitĂ© Paris CitĂ©. Her interdisciplinary research investigates how social communication develops and unfolds in interaction, with a particular focus on laughter as a window onto pragmatic, cognitive and interpersonal processes. Combining naturalistic, experimental and computational approaches, she studies communication across development and neurotypes, from early caregiverâchild interaction to adult conversation. Her current research focuses particularly on interpersonal dynamics in typical and atypical neurodevelopment, including autism and deaf and hard-of-hearing populations.

âWhat is laughter in the wild? Investigating machine perception of laughter as a multimodal multisensor problemâ
In this talk, I will discuss two works that tried to investigate the multimodal nature of laughter. Traditionally, it has been viewed as a predominantly vocal phenomenon with some exceptions acknowledging the physical nature of it. In this talk, I will discuss the practical and technical challenges of in the wild laughter detection, specifically investigating the role of annotator subjectivity, modality access, and its influence on model learning.
Hayley Hung is an Associate Professor at the Technical University of Delft, working on Socially Aware Surveillance Systems. She leads the recently formed Perceptive Computing Lab, which is part of the Pattern Recognition and Bioinformatics Group. Previously, she had a Marie Curie Postdoctoral Research fellowship on the AnaSID (Analysing Social Interactions from a Distance) project, in the Intelligent Autonomous Systems Group at the University of Amsterdam, working with Ben Krose. Before that, she was a PostDoc at IDIAP working on multimodal meeting analysis for modelling dominance and influence in meetings, working with Daniel Gatica-Perez. Before this, she was at Queen Mary University Vision Group as a PhD student supervised by Sean Gong.

Submission process
Submission to the LaugHSMI workshop is double-blind. The workshop accepts short research papers (4 pages, excluding references) and full-length papers (8 pages, excluding references). Authors are required to follow standard ACM ICMI paper format.
Short research papers can describe work in progress, position papers, datasets, or research papers that have been already published in another venue (conference or journal) in the last 12 months that are relevant to LaugHSMIâs topics of interest. For already published works, please submit a summarized four-page short paper.
All submissions should be submitted through OpenReview before the deadline (see important dates below).
All submissions will be reviewed by at least two non-conflicting reviewers. All papers will be presented during a dedicated poster session. Selected full-length and short papers will also be presented as oral presentations throughout the day.
It is expected that at least one author of each accepted paper will register for the workshop and present the work during the event. Online presentations will be considered for presenters who cannot attend in person due to visa or personal constraints.
If you have any questions, do not hesitate to contact the organizers (see contacts below).

- Papers acceptance notification: July 22nd, 2026
- Camera-ready deadline: August 1st, 2026
