SIVA'23 - Workshop on Socially Interactive Human-like Virtual Agents

Workshop description

From expressive and context-aware multimodal generation of digital humans to understanding the social cognition of real humans

Due to the rapid growth of virtual, augmented, and hybrid reality together with spectacular advances in artificial intelligence, the ultra-realistic generation and animation of digital humans with human-like behaviors is becoming a massive topic of interest. This complex endeavor requires modeling several elements of human behavior including the natural coordination of multimodal behaviors including text, speech, face, and body, plus the contextualization of behavior in response to interlocutors of different cultures and motivations. Thus, challenges in this topic are two folds—the generation and animation of coherent multimodal behaviors, and modeling the expressivity and contextualization of the virtual agent with respect to human behavior, plus understanding and modeling virtual agent behavior adaptation to increase human’s engagement. The aim of this workshop is to connect traditionally distinct communities (e.g., speech, vision, cognitive neurosciences, social psychology) to elaborate and discuss the future of human interaction with human-like virtual agents. We expect contributions from the fields of signal processing, speech and vision, machine learning and artificial intelligence, perceptual studies, and cognitive and neuroscience. Topics will range from multimodal generative modeling of virtual agent behaviors, and speech-to-face and posture 2D and 3D animation, to original research topics including style, expressivity, and context-aware animation of virtual agents. Moreover, the availability of controllable real-time virtual agent models can be used as state-of-the-art experimental stimuli and confederates to design novel, groundbreaking experiments to advance understanding of social cognition in humans. Finally, these virtual humans can be used to create virtual environments for medical purposes including rehabilitation and training.

This workshop, organized by renowned scientists in complementary domains, aims to connect communities of research scientists interested in virtual agents and human-agent or human-human interactions, with impact for future technological innovations and fundamental knowledge of human social behavior. Specifically, Mixing participants from academia and industry, participants will present and discuss current research trends and envision frontiers in the modeling and generation of human-like multimodal behavior and their application to the fields of neuroscience and social cognition. Further, mixing computational and cognitive neuroscience communities will enable knowledge exchange about human multimodal behavior and cognition to in turn create virtual agents capable of natural, engaging, and seamless multimodal social behavior with real humans.

SIVA'23 is organized as a satellite workshop of the IEEE International Conference on Automatic Face and Gesture Recognition 2023

Paper Submission

Submissions to SIVA'23 should have no substantial overlap with any other paper already submitted or published, or to be submitted during the SIVA'23 review period. All persons who have made any substantial contribution to the work should be listed as authors, and all listed authors should have made some substantial contribution to the work. All authors should be aware that the paper is submitted to SIVA'23.

Papers presented at the SIVA'23 workshop will be published as part of the proceedings of the main FG'2023 conference and should, therefore, follow the same presentation guidelines as the main conference. Workshop papers will be included in IEEE Xplore.

The reviewing process for SIVA'23 will be “single-blind”, which means that only reviews are anonymous.

The submission process will be handled through the CMT System.

Two submission formats are proposed:

- Short paper : 3 pages + 1 extra page for references
- Long paper : 6 to 8 pages including references

Short papers encourage submissions of early research in original emerging fields.
Long papers promote the presentation of strongly original contributions, positional or survey papers.

Papers that use different formatting from the FG 2023 Latex or Word templates or exceeds the expected length will be automatically removed from the reviewing process.

Supplementary material (images, video, etc.) may optionally be submitted with papers, but be sure to maintain anonymity, including the file properties or other hidden text. The supplemental material has a file size limit of 100MB. The supplemental materials will not be part of the conference proceedings, so they are only there to aid the reviewing process. Reviewers are not required to view the supplemental material (though most reviewers are likely to do so), so any information critical to understanding the work should be in the main paper.

All supplementary material must be self-contained and zipped into a single file. The following formats are allowed: avi, mp4, pdf, wmv. Note that reviewers will be encouraged to look at it, but are not obligated to do so.


  1. Prepare your manuscripts as per the IEEE specification using the provided Latex or Word templates
  2. Carefully proofread your submission;
  3. Submit to the SIVA'23 CMT system.

NOTE: List all authors during initial submission. Modifying the author list after the review process is not allowed.

Diversity, Equity & Inclusion

The format of this workshop will be hybrid online and onsite. This format proposes format of scientific exchanges in order to satisfy travel restrictions and COVID sanitary precautions, to promote inclusion in the research community (travel costs are high, online presentations will encourage research contributions from geographical regions which would normally be excluded), and to consider ecological issues (e.g., CO2 footprint). The organizing committee is committed to paying attention to equality, diversity, and inclusivity in consideration of invited speakers. This effort starts from the organizing committee and the invited speakers to the program committee.
