The 31st Annual ACM Conference on Intelligent User Interfaces (IUI 2026)
*** Call for Papers, Workshop & Tutorial Proposals ***
The 31st Annual ACM Conference on Intelligent User Interfaces (IUI 2026)
March 23-26, 2026, 5* Coral Beach Hotel & Resort, Paphos, Cyprus
https://iui.hosting.acm.org/2026/
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).

Papers
We invite original paper submissions that are not under consideration elsewhere. Accepted
papers will appear in the ACM Digital Library and citation indices. At least one author of all
accepted papers must register with full registration fee (not student registration fee), attend in
person, and present their paper during the main conference program. One registration covers
one paper only.
A selected set of accepted top-quality full papers will be invited to submit their extended
versions for publication in an ACM Transactions on Interactive Intelligent Systems (TiiS) special
issue titled âHighlights of IUI 2026â that will appear in 2027.
Reflection of practical and societal impact
We encourage authors to consider practical and societal implications of their work (as well as
its shortcomings) throughout their projects and to include a reflection on those implications in
their papers, in particular how the proposed methods and insights could be applied and
deployed in a realistic setting and how they can improve people’s lives in the real world.
We also encourage authors to discuss potential ethical considerations of their work in terms of
diversity, inclusion, and equality; and other topics under the broad responsible AI topic and its
societal impact. We recognize that technology is rarely neutral — simply by making some
things easier than others, it reshapes society (Winner, 1980; Green, 2020). Further, given the
incredibly short invention-to-application cycles for AI-related technologies, it is becoming
increasingly unlikely that âsomebody elseâ will carefully consider how an emerging intelligent
user interface technology might impact the world before this technology is deployed. Our
purpose is to help authors ensure that the likely societal consequences of their work are
consistent with their intentions and values. For colleagues who are not yet experienced with
incorporating societal impacts into their IUI research but who are willing to give it a try, here
are some ideas to consider.
Anonymization
ACM IUI uses a double-blind review process. All submissions (and supplemental materials)
must be appropriately anonymized according to the following guidelines:
⢠Authors’ names and affiliations are not visible anywhere in the paper.
⢠Acknowledgements should be anonymized or removed during the review process.
⢠Self-citations should be included where necessary but must use the third person. For
example, “… as shown in our previous user study [2] … ” is not allowed, whereas “… as shown
in Smith et al. [2] ” is acceptable (because in this case the citation [2] will NOT be perceived as
self-citation).
Failure to follow these guidelines may result in submissions being desk-rejected without review.
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 authorâs own text. Authors should include a âGenAI Usage
Disclosureâ 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.
Research Involving Human Participants and Subjects
Any research in submitted manuscripts that involves human subjects must go through the
appropriate ethics review requirements that apply to the authorsâ research environment. As
research environments vary considerably with regard to their requirements, authors are asked
to submit a short note to reviewers that provides this context. Please also see the 2021 ACM
Publications policy on research involving human participants and subjects before submitting.
Additional Policies
Authors should also be aware of the SIGCHI Policy for Submission and Review at SIGCHI
Conferences and ACM Publications Policies.
Submission Format, Length, and Platform
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,anony mous]{acmart} for the LaTeX template.
Papers are of variable length. Paper length must be proportional to its contribution. We
encourage authors to stay within a 10,000 word limit. Authors of papers exceeding 12,000
words should add a note at the end of their manuscript explaining how the length of the paper
is commensurate with the contribution of the work.
Submission Platform (for Papers)
All materials must be submitted electronically to the Precision Conference Submission (PCS)
Portal (https://new.precisionconference.com/) by the abstract and paper deadlines.
In PCS, first click âSubmissionsâ at the top of the page, from the dropdown menus for Society,
Conference, and Track, please select âSIGCHIâ, âIUI 2026â, and âIUI 2026 Papersâ, respectively,
and then press âGoâ.
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 âPublication and Open Accessâ.
Supplemental Materials
Submitting supplemental material (e.g., questionnaires, demo videos of applications, data
sheets) is optional but encouraged.
If supplying a demo video, please follow the SIGCHI Technical Requirements and Guidelines for
videos.
Publication and Open Access
The official publication date is the date the proceedings are made available in the ACM Digital
Library. This date may be up to two weeks prior to the first day of the conference. The official
publication date affects the deadline for any patent filings related to published work.
Starting January 1, 2026, ACM will fully transition to Open Access. All ACM publications,
including those from ACM-sponsored conferences, will be 100% Open Access. Authors will
have two primary options for publishing Open Access articles with ACM: the ACM Open
institutional model or by paying Article Processing Charges (APCs). With over 1,800 institutions
already part of ACM Open, the majority of ACM-sponsored conference papers will not require
APCs from authors or conferences (currently, around 70-75%).
Authors from institutions not participating in ACM Open will need to pay an APC to publish
their papers, unless they qualify for a financial or discretionary waiver. To find out whether an
APC applies to your article, please consult the list of participating institutions in ACM Open and
review the APC Waivers and Discounts Policy. Keep in mind that waivers are rare and are
granted based on specific criteria set by ACM.
Understanding that this change could present financial challenges, ACM has approved a
temporary subsidy for 2026 to ease the transition and allow more time for institutions to join
ACM Open. The subsidy will offer:
* $250 APC for ACM/SIG members
* $350 for non-members
This represents a 65% discount, funded directly by ACM. Authors are encouraged to help
advocate for their institutions to join ACM Open during this transition period.
This temporary subsidized pricing will apply to all conferences scheduled for 2026.
Workshop and Tutorial Proposals
We are pleased to invite proposals for workshops and tutorials to be held in conjunction with
the 31st International ACM Conference on Intelligent User Interfaces (ACM IUI 2026), Paphos,
Cyprus.
Workshops aim to provide a venue for presenting research on emerging or specialized topics
of interest and to offer an informal forum for discussing research questions and challenges.
Potential workshop topics should be related to the general theme of the conference
(âWhere HCI meets AIâ).
Tutorials aim to provide fundamental knowledge and experience on topics related to intelligent
user interfaces and the intersection between Human-Computer Interaction (HCI) and Artificial
Intelligence (AI).
We welcome proposals for a wide range of *full-day* or *half-day* workshops and tutorial
formats and activities, including but not limited to:
⢠Mini Conferences: Workshops that focus on a specific topic and may have their own paper
submission and review processes.
⢠Interactive Formats: Workshops that encourage active participation and hands-on
experiences through break-out sessions or group work to explore specific topics. They may
have their own paper submission and review process or target a report summarizing the
discussions and outcomes.
⢠Emerging Work Sessions: Workshops that foster discussion around emerging ideas.
Organizers may raise specific topics and invite position papers, late-breaking results, or
extended abstracts.
⢠Project-Centric Formats: Workshops tied closely to a specific existing large-scale funded
project(e.g., NSF, EU) with the goal to engage a broader community.
⢠Interactive Competitions: Formats that invite individuals and teams to participate in
challenges or hackathons on selected topics relevant to IUI.
⢠Tutorials: Sessions that provide a structured instruction on topics aligned with the conference
theme, such as HCI methods, AI techniques, methodological frameworks, or tools for building
intelligent user interfaces.
Review and Oversight by Workshop and Tutorial Chairs
Proposals will be reviewed and evaluated by the Workshop and Tutorial Chairs. It is possible
that workshops may be cancelled, shortened, merged, or restructured if there are insufficient
submissions.
Workshop and Tutorial summaries will be included in the ACM Digital Library for ACM IUI 2026.
We will also publish joint workshop proceedings for accepted workshop submissions (through
CEUR or a similar venue).
Responsibilities of Workshop and Tutorial Organizers
⢠Coordinate the Call for Papers, including solicitation, submission handling, and peer review
process.
⢠Create and maintain a dedicated website with Workshop or Tutorial information. The IUI
Website 2026 will link to this page.
⢠Prepare and communicate Call for Participation, targeting both IUI and broader relevant
communities (e.g., via mailing lists, social media, newsgroups, or offline events)
⢠Facilitate the planned activities, including paper presentations, discussions, and/or
interactive elements.
⢠Submit a workshop or tutorial summary for inclusion in the ACM Digital Library.
⢠Collect camera-ready papers and author agreements from workshop participants for the joint
workshop proceedings (CEUR or similar).
Note that for the joint proceedings (CEUR or similar), submissions should be peer-reviewed
and will need to meet publishersâ guidelines. CEUR, for example, requires a 5-page minimum
per contribution. Note that not all workshop and tutorial formats listed above may meet these
requirements, and we may not be able to include them.
IUI 2026 is an in-person event, and we expect workshop organizers to attend, allowing the
workshop to be conducted on-site. One author per paper is expected to attend in person to
present the work.
