Call for Submissions:

ACM 25th International Conference on Intelligent Virtual Agents
September 16-19, 202
Berlin, Germany
https://iva.acm.org/2025/

Deadline for submission of abstracts: April 4, 2025

Intelligent Virtual Agents (IVA) Annual Conference is the premier international event for interdisciplinary research on the design, application, and evaluation of Virtual Agents with social interaction capabilities.

IVA 2025, the 25th Annual Conference, will be held in Berlin, Germany, September 16-19, 2025.

IVAs are interactive characters that exhibit human-like capabilities, including communicating using natural human modalities such as facial expressions, speech, and gestures. IVAs are also capable of real-time perception, cognition, emotion, and action that allow them to participate in dynamic social interactions.

IVA 2025 aims to showcase cutting-edge research on the design, application, and evaluation of IVAs, as well as the basic research underlying the technology that supports human-agent interaction, such as social perception, dialog modeling, and social behavior planning. We also welcome submissions on central theoretical issues, uses of virtual agents in psychological research and showcases of working applications.

Aesthetics and Culture: This year’s theme explores how exploiting aesthetic principles and cultural nuances for Socially Interactive Agents fosters user trust, comfort, and willingness to engage. It also examines how culturally informed design cues reduce barriers and promote more intuitive, socially meaningful human-machine collaboration.

IVA 2025 offers the following submission tracks:

• Full papers: 4 to 8 pages (not including references): https://iva.acm.org/2025/call-for-papers
• Posters: 2 to 3 pages (not including references):  https://iva.acm.org/2025/call-for-scientific-and-artistic-posters-submissions/
• Demo & Artwork: 2 pages + visuals: https://iva.acm.org/2025/call-for-demos

CALL FOR FULL PAPERS

All submissions will be double-blind peer-reviewed by expert reviewers. All accepted full-paper submissions will be presented orally and published in the proceedings.

Interdisciplinary Format:

IVA is a highly interdisciplinary conference that recognizes varying publication norms across disciplines. For instance, conference publications are standard in Computer Science, while journal publications prevail in Psychology. To promote trans-disciplinary interaction, authors can decide whether their accepted full paper with the supplemental material will be included in the ACM Digital Library or not.

SCOPE AND LIST OF TOPICS

IVA invites submissions on a broad range of topics, including but not limited to:

Agent design and modeling of:

• Cognition
• Emotion (including personality and cultural differences)
• Socially communicative behavior (e.g., of emotions, personality traits)
• Conversational behavior
• Social perception
• Machine learning approaches to agent modeling
• Approaches to realizing adaptive behavior
• Models informed by theoretical and empirical research in psychology

Multimodal interaction:

• Verbal and nonverbal behavior coordination
• Face-to-face communication skills
• Engagement
• Managing co-presence and interpersonal relation
• Multi-party interaction
• Data-driven multimodal modeling

Social agent architectures:

• Design criteria and design methodologies
• Engineering of real-time human-agent interaction
• Standards / measures to support interoperability
• Portability and reuse
• Specialized tools, toolkits and toolchains

Evaluation methods and studies:

• Evaluation methodologies and user studies
• Ethical considerations and societal impact
• Applicable lessons across fields (e.g. between robotics and virtual agents)
• Social agents as a means to study and model human behavior

Applications:

• Applications in education, skills training, health, counseling, games, art, etc.
• Virtual agents in games and simulations
• Social agents as tools in psychology
• Migration of agents between platforms

Note: IVA 2025 will as usual have workshops/tutorials and a doctoral consortium. Details on submissions can be found at the web site:  https://iva.acm.org/2025/

INSTRUCTIONS FOR AUTHORS

Full paper submissions should be anonymous and prepared in the “ACM Standard” format, more specifically the “SigConf” format.

• The LaTeX template for the “ACM Standard”/”SigConf” format can be found inside the official ACM Master article template package. Please use the most recent version (2.12) available at:
  https://www.acm.org/publications/proceedings-template
• The “ACM Standard” Microsoft Word template is currently not part of the downloadable package as the ACM is currently revising it to improve accessibility of resulting PDF-documents. Please use the “Interim Word Template” instead:  https://www.acm.org/binaries/content/assets/publications/word_style/interim-template-style/interim-layout.docx
• “By submitting your article to an ACM Publication, you are hereby acknowledging that you and your co-authors are subject to all ACM Publications Policies, including ACM’s new Publications Policy on Research Involving Human Participants and Subjects. Alleged violations of this policy or any ACM Publications Policy will be investigated by ACM and may result in a full retraction of your paper, in addition to other potential penalties, as per ACM Publications Policy.”
• “Please ensure that you and your co-authors obtain an ORCID ID, so you can complete the publishing process for your accepted paper.  ACM has been involved in ORCID from the start and we have recently made a commitment to collect ORCID IDs from all of our published authors. We are committed to improve author discoverability, ensure proper attribution and contribute to ongoing community efforts around name normalization; your ORCID ID will help in these efforts.”

All submissions should be in PDF-format.

Please refer to the poster and demo CFPs for instructions for these formats.
