The ACM Conference on Intelligent User Interfaces (ACM IUI) is the leading annual venue for researchers and practitioners to explore advancements at the intersection of Artificial Intelligence (AI) and Human-Computer Interaction (HCI). IUI submissions should address HCI challenges using machine intelligence and consider both computational and human- centric aspects. As AI becomes more integrated into everyday technology, understanding its role in meeting human needs is vital for developing effective and responsible systems. This conference fosters collaboration among experts from diverse fields to tackle significant issues in AI and HCI through discussions, workshops, and networking sessions.
UI 2026 attracted a record number of submissions for the main conference (561 full paper submissions after an initial submission of 697 abstracts).
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.

We adopt the ACM TAPS Workflow. Please prepare your submission for review in a single column format, using the latest templates: Word Submission Template, or the LaTeX template using \documentclass[manuscript,review,anonymous]{acmart} for the LaTeX template.
Authors are required to include a proper classification for the paper according to the ACM Classification System (CCS). Additional information on how to use it is available at: https://dl.acm.org/ccshttp://www.cs.ucy.ac.cy/~george/GPLists_2021/lm.php?tk=Y29ycG9yYQkJCWNvcnBvcmFAbGlzdC5lbHJhLmluZm8JVGhlIEFubnVhbCBBQ00gQ29uZmVyZW5jZSBvbiBJbnRlbGxpZ2VudCBVc2VyIEludGVyZmFjZXMgKElVSSAyMDI2KTogU2Vjb25kIENhbGwgZm9yIFBvc3RlcnMgYW5kIERlbW9zCTQyOQlJVUkyMDI2CTc2CWNsaWNrCXllcwlubw==&url=https%3A%2F%2Fdl.acm.org%2Fccs .
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/http://www.cs.ucy.ac.cy/~george/GPLists_2021/lm.php?tk=Y29ycG9yYQkJCWNvcnBvcmFAbGlzdC5lbHJhLmluZm8JVGhlIEFubnVhbCBBQ00gQ29uZmVyZW5jZSBvbiBJbnRlbGxpZ2VudCBVc2VyIEludGVyZmFjZXMgKElVSSAyMDI2KTogU2Vjb25kIENhbGwgZm9yIFBvc3RlcnMgYW5kIERlbW9zCTQyOQlJVUkyMDI2CTc2CWNsaWNrCXllcwlubw==&url=https%3A%2F%2Fsigchi.org%2Fresources%2Fguides-for-authors%2Fvideos%2F).
Please submit your demos and posters electronically to the Precision Conference Submission (PCS) Portal (https://new.precisionconference.com/user/loginhttp://www.cs.ucy.ac.cy/~george/GPLists_2021/lm.php?tk=Y29ycG9yYQkJCWNvcnBvcmFAbGlzdC5lbHJhLmluZm8JVGhlIEFubnVhbCBBQ00gQ29uZmVyZW5jZSBvbiBJbnRlbGxpZ2VudCBVc2VyIEludGVyZmFjZXMgKElVSSAyMDI2KTogU2Vjb25kIENhbGwgZm9yIFBvc3RlcnMgYW5kIERlbW9zCTQyOQlJVUkyMDI2CTc2CWNsaWNrCXllcwlubw==&url=https%3A%2F%2Fnew.precisionconference.com%2Fuser%2Flogin) by the paper deadlines.
In PCS, first click “Submissions” at the top of the page, from the dropdown menus for Society, Conference, and Track, please select “SIGCHI”, “IUI 2026”, and “IUI 2026 Posters” or “IUI 2026 Demos”, respectively, and then press “Go”.
Note: If the corresponding author (the individual who submits the paper, not necessarily the first author) is affiliated with a participating institution that has an open access agreement with ACM, the Article Processing Charges (APCs) will be waived for publishing the paper. Details are under “Publication and Open Access”.
Accessibility
Authors are asked to make their paper submissions accessible (so that reviewers with vision impairments can access them, for example). The authors of accepted papers will be required to make their final PDFs accessible. Please use the SIGCHI Guide to an Accessible Submission for detailed instructions.
If you are submitting a video as supplemental material, please provide captions, as described in Technical Requirements and Guidelines for Videos.
Please refer to the Accessibility page of the conference site for further details and guidelines.
Usage of Generative AI
All submissions must comply with the ACM policy on the usage of GenAI: the April 2023 ACM Policy on Authorship and Frequently Asked Questions. Text generated from a large-scale language model (LLM), such as ChatGPT, must be clearly marked where such tools are used for purposes beyond editing the author’s own text. Authors should include a “GenAI Usage Disclosure” section, right before the references, to provide full disclosure of all use of GenAI tools in all stages of the research (including the code and data) and the writing. This section, together with the references, will not be counted toward the word limit.
While we do not anticipate using tools on a large scale to detect LLM-generated text, we will investigate submissions brought to our attention and desk reject papers where LLM use is not clearly marked.
