HCOMP 2026 — The 2026 ACM Conference on Human-AI Complementarity and Alignment

HCOMP 2026, the ACM Conference on Human-AI Complementarity and Alignment, runs 27-30 September 2026 at Virginia Tech's Academic Building One in Alexandria, Virginia, just outside Washington, DC. Organisers describe HCOMP as the premier venue for disseminating the latest research findings on human-AI complementarity and alignment: the community studies and designs systems that combine the complementary strengths of human and artificial intelligence to achieve outcomes neither could achieve alone, in ways that are ethical, safe and intentional. The conference has just made a significant move — after a decade as an AAAI series focused on human computation and crowdsourcing, it transitioned to ACM and made human-AI complementarity and alignment its permanent core theme. This edition is co-located and tightly integrated with the 2026 ACM Collective Intelligence Conference under the shared theme 'Connections'.

• ✓Heads of AI / Chief AI Officers
• ✓AI governance and responsible-AI leads
• ✓VPs of Engineering
• ✓Applied research directors
• ✓AI/ML engineers
• ✓Product leaders building human-in-the-loop systems
• ✓Data science managers

Every enterprise deploying AI eventually hits the same wall: the system is good enough to help and not good enough to trust alone, so the real design problem is how the human and the model divide the work. This is the one conference organised entirely around that question, with peer-reviewed evidence rather than vendor demos on where oversight actually catches errors and where it merely feels reassuring. For a head of AI or a governance lead, that is directly usable in review boards and deployment sign-offs, and the Washington DC location makes it a practical stop for anyone whose AI programme has a federal or regulatory dimension.

• ✓Papers and Talks track — the core peer-reviewed programme
• ✓Workshops selected from a dedicated proposal round
• ✓Posters and demos track
• ✓Theme: 'Connections' — submissions exploring connections across disciplines; across humans, animals and machines; between individuals and communities
• ✓Co-located 2026 ACM Collective Intelligence Conference, which adds a doctoral consortium and CrowdCamp to the shared programme

• ★The only ACM conference whose permanent core theme is human-AI complementarity and alignment — a subject most venues treat as one track among many
• ★Just rebased from AAAI to ACM after a decade as the human computation and crowdsourcing series, so this edition sets the shape of the venue going forward
• ★Co-located and tightly integrated with the 2026 ACM Collective Intelligence Conference rather than merely sharing a hotel, which puts the human-AI and collective-intelligence communities in the same sessions
• ★Held minutes from Washington, DC, which reliably pulls in federal and policy attendees that a West Coast venue does not
• ★Backed by the National Science Foundation, Bloomberg Engineering and the Virginia Tech Institute for Advanced Computing
