The ACM Conference on Intelligent User Interfaces (ACM IUI) is the annual premier venue where researchers and practitioners meet and discuss state-of-the-art advances at the intersection of Artificial Intelligence (AI) and Human-Computer Interaction (HCI). Ideal IUI submissions should address practical HCI challenges using machine intelligence and discuss both computational and human-centric aspects of such methodologies, techniques, and systems.

This area is crucial as AI is increasingly integrated into everyday technology. Understanding and shaping AI systems for human needs is essential to ensure that AI systems are effective and responsible. As these techniques become increasingly powerful, new use cases and human-AI interactions can be explored. This conference offers an opportunity to focus the research community on important problems at the intersection of AI and HCI and bring together experts from various disciplines to discuss and build on these ideas in workshops, breaks, and networking sessions.

Contributions are welcome from all relevant arenas, including academia, industry, government, and non-profit organizations. Diverse insights are critical to the vitality of the IUI community, and the conference will accept papers for both long and short oral presentations. Contributions to IUI are expected to be supported by rigorous evidence appropriate to the claims (e.g., user study, system evaluation, computational analysis).
