CALL FOR CONTRIBUTIONS HHAI 226 - Hybrid Human-Artificial Intelligence July 6–10, 2026, Brussels, Belgium -------------------------------------------------- Hybrid Human-Artificial Intelligence (HHAI) is an international conference series that focuses on the study of Artificial Intelligence systems that cooperate synergistically, proactively and purposefully with humans, amplifying instead of replacing human intelligence. HHAI aims for AI systems that work together with humans, emphasizing the need for adaptive, collaborative, responsible, interactive and human-centered intelligent systems. HHAI systems leverage human strengths and compensate for human weaknesses, while taking into account social, ethical and legal considerations. HHAI 2026 will be held on July 6-10, 2026, in Brussels, Belgium, and is the fifth conference in the series. The HHAI field is driven by developments in AI, but it also requires fundamentally new approaches and solutions. Thus, we encourage collaborations across research domains such as AI, HCI, cognitive and social sciences, philosophy and ethics, complex systems, and others. In this fifth international conference, we invite scholars from these fields to submit their best original – published, new as well as in progress – works, and visionary ideas on Hybrid Human-Artificial Intelligence. **Join the HHAI community and keep up with the news:** Website: https://hhai-conference.org/2026/ Linkedin: https://www.linkedin.com/company/hhai-conference/ You can contribute in many ways; Check out the Call for papers <https://hhai-conference.org/2026/cfp/> Call for workshops and tutorials <https://hhai-conference.org/2026/workshops-and-tutorials/> Call for demos and posters <https://hhai-conference.org/2026/call-for-posters-and-demos/> Call for contributions in the Doctoral consortium <https://hhai-conference.org/2026/doctoral-consortium/> This year, the main track also invites extended abstracts on research published in high-quality journals starting from publications starting in January 2025.
