Call for Participation: ACM Intelligent User Interfaces (IUI) 2022, March 21-25, 2022 Virtually hosted by the University of Helsinki http://iui.acm.org/2022/ @ACMIUI Please join us at the ACM Conference on Intelligent User Interfaces (ACM IUI) for discussion and dissemination of research on the design, development, and evaluation of human-oriented AI systems, that is, systems that people directly interact with and that incorporate some aspects of machine intelligence. Specific examples of such systems include perceptual user interfaces, intelligent assistants, conversational agents, adaptive systems, and more. ACM IUI supports this multidisciplinary approach to research and innovation by bringing together researchers and practitioners from the fields of Human-Computer Interaction (HCI), Artificial Intelligence (AI), Machine Learning (ML), and others. We have an exciting program <https://programs.sigchi.org/iui/2022> of keynotes, papers, panels, posters and demos, as well as a doctoral consortium. There are also workshops which are included in the main conference registration fee.
