Hybrid Human-Artificial Intelligence (HHAI 2026)

Hybrid Human-Artificial Intelligence (HHAI) is an international conference series dedicated to the study of Artificial Intelligence systems designed to work with, rather than in place of, humans. The conference brings together research on AI systems that collaborate synergistically, proactively, and purposefully with people, with the goal of amplifying human intelligence instead of replacing it.

Scope

HHAI invites contributions that advance the development of adaptive, collaborative, responsible, and ethical human-centered intelligent systems. We particularly welcome submissions that explore how HHAI systems can leverage human strengths and compensate for human limitations, while taking into account the social, ethical and legal implications of human-AI interaction.

Although the HHAI field is driven by developments in AI, it also requires fundamentally new approaches and interdisciplinary solutions. We therefore encourage contributions that bridge AI with other research domains such as HCI, cognitive and social sciences, philosophy and ethics, complex systems, among others. We invite scholars from these and other relevant fields to submit original, high-quality work, including mature research, work in progress, and visionary ideas that advance the state of the art in Hybrid Human-Artificial Intelligence.

Note that this year we also provide the option to send in an abstract on work published in journals, relevant for the theme of this conference (see below).

HHAI 2026 will be held on July 6–10, 2026, in Brussels, Belgium, and is the fifth edition of this international conference.

Location

HHAI 2026 will be an in-person, single-track conference organized in Brussels, Belgium. Workshops and tutorials (6-7 July) as well as the main conference (8-10 July) will be held at the Vrije Universiteit Brussel and the Université Libre de Bruxelles in Belgium, Campus Etterbeek – La Plaine.

Topics

We invite research on different challenges in Hybrid Human-Artificial Intelligence. The following list of topics is illustrative, not exhaustive:

Human-AI interaction, interpretation and collaboration
Adaptive human-AI co-learning and co-creation
Learning, reasoning and planning with humans and machines in the loop
User modeling and personalisation
Integration of learning and reasoning
Transparent, explainable, and accountable AI
Fair, ethical, responsible, and trustworthy AI
Societal awareness of AI
Multimodal machine perception of real-world settings
Social signal processing
Representations learning for Communicative or Collaborative AI
Symbolic representations for human-centric AI
Human-AI Coevolution
Foundation models and humans
Human cognition-aware AI
Decentralized human-AI systems
Reliability and robustness in human-AI systems
Applications of hybrid human-AI intelligence
We welcome contributions about all types of technology, from robots and conversational agents to multi-agent systems and machine learning models.

Paper types

In this conference, we wish to stimulate the exchange of novel ideas and interdisciplinary perspectives. To do this, we will accept three different types of papers:

Full papers present original, impactful work (12 pages excluding references)

Blue sky papers present visionary ideas to stimulate the research community (8 pages excluding references)

Working papers present work in progress (8 pages excluding references)

Extended abstracts present published journal articles from January 2025 onwards (3 pages excluding references)

Accepted full papers and Blue sky papers will be published in the Proceedings of the Fifth International Conference on Hybrid Human-Machine Intelligence, in the Frontiers of AI series by IOS Press. Working papers and extended abstracts can be included in the proceedings, unless the authors request the paper to remain unpublished.

Reviewing process & Submission guidelines

Submissions of full, blue-sky, and working papers should be original work without substantial overlap with pre-published papers. All submissions should adhere to IOS formatting guidelines. Papers should be written in English and detailed submission instructions can also be found here: https://hhai-conference.org/2026/submission-instructions/.
