*Call for Demo and Poster IUI2025* ** *Important Dates* * Submission Deadline: *January 7 (Tuesday), 2025* * Notification to Authors: February 4 (Tuesday) 2025 * Camera Ready Deadline: February 10 (Monday), 2025 ACM Conference on Intelligent User Interfaces (ACM IUI) 2025 is the 30th annual premiere venue, where researchers and practitioners will 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. We welcome contributions from related fields such as psychology, behavioral science, cognitive science, computer graphics, design, the arts, and more. Our focus is to improve the interaction between humans and machines, by leveraging both HCI approaches and state-of-the-art AI techniques from machine learning, natural language processing, data mining, knowledge representation and reasoning. ACM IUI welcomes contributions from all relevant arenas, academia, industry, government, and non-profit organizations, and gives its participants the opportunity to present and see cutting-edge IUI work in a focused and interactive setting. *Posters* Posters provide an opportunity for sharing valuable last-minute ideas, eliciting useful feedback on early-stage work and fostering discussions and collaborations among colleagues. We invite submissions relevant to all conference topics. All submissions should convey a scientific result or work in progress that is not yet ready to be published as a full-length research paper at a refereed conference. The page limit for poster papers is 4 pages (references do not count toward the page limit). Submitting a draft poster along with your submission is not required but is recommended. Accepted poster papers will appear in the companion proceedings of the conference. Each accepted contribution is expected to be presented in person during the poster session. *Demos* The demonstration track complements the overall program of the conference. Demonstrations show implementations of novel, interesting, and important intelligent user interface concepts or systems. We invite submissions relevant to intelligent user interfaces and which address, but are not limited to, the topics of the conference. All submissions are intended to convey a scientific result or work in progress and should not be advertisements for commercial software packages. The page limit for demo papers is 4 pages (references do not count toward the page limit). Authors further need to submit a video (max. 5 mins) along with their demo paper to showcase their work. Accepted demo papers will be presented as interactive demonstrations at IUI and published in the companion proceedings of the conference. Each accepted contribution is expected to be presented in person during the demo sessions. Authors who submitted a long or short research paper are welcome to also propose a demo of their work to exemplify their work at the conference (In this case, the paper will not be included in the ACM Digital Library). Alternatively, the authors of accepted papers may also opt to submit a regular 4-page paper for the demonstration, which will be included in the ACM Digital Library if accepted. *Topics* In addition to the conference topics, we would like to encourage authors to also consider the following topics: * Enhance Web Accessibility through the AI * Intelligent Human-Robot Applications * Designing Interfaces for GenAI Systems * Applications of Intelligent User Interfaces to Support Underrepresented Users * Societal and Ethical Considerations of Intelligent User Interfaces, Particularly as Prompted by Emerging Technology such as GenAI *Submission Instructions* A video (up to 5 mins) is required for demo submissions. The video should showcase the system that will be demonstrated during the conference. Please follow the SIGCHI Technical Requirements and Guidelines for Videos. <https://sigchi.org/resources/guides-for-authors/videos/> Please submit your demos and posters at http://new.precisionconference.com/~sigchi <http://new.precisionconference.com/~sigchi>under the IUI 2025 Demos and Posters track. In PCS 2.0, first click "Submissions" at the top of the page, from the dropdown menus for society, conference, and track select "SIGCHI", "IUI 2025" and "IUI 2025 Posters and Demos", respectively, and press "Go". Looking forward to your submissions! IUI’25 Organizers
