*** Second Call for 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/
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 (“Where HCI meets AI”).
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 *full-day*, *half-day* or *quarter-day* 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, tools, labs or hands-on experiences 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 publishers’ 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.
Proposal Format
Workshop or tutorial proposals should be a maximum of four pages long (single-column format). Prepare your submission using the latest templates: Word Submission Template (https://authors.acm.org/binaries/content/assets/publications/taps/acm_submis...), or the LaTex Template (https://authors.acm.org/proceedings/production-information/preparing-your-ar...). For Latex, please use “\documentclass[manuscript,review]{acmart}”.
The proposals should be organized as follows:
• Name and title: A one-word acronym and a full title. Please indicate “(Workshop)” or “(Tutorial)” after the title, as appropriate.
• Abstract: A brief summary of the workshop or tutorial.
• Description of workshop or tutorial topic: Should discuss the relevance of the proposed topic to IUI and its interest for the IUI 2026 audience. Include a concise discussion of why this workshop or tutorial is particularly relevant for the intended audience and how it will complement and enhance topics covered at the main conference.
• Previous history: List of previous workshops or tutorials on this topic, including the conferences that hosted them and the number of participants. If available, report on past editions of the workshop (including URLs), along with a brief statement of the workshop series (e.g., covering topics, number of paper submissions, and participants), as well as post-workshop publications over the years and acceptance statistics. If this is the first edition of the workshop, describe how it differs from others on similar topics (e.g., by including conference names and years).
• Organizer(s): Names, affiliations, emails, and web pages of the organizer(s). Provide a brief description of the background of the organizer(s). Strong proposals normally include organizers who bring differing perspectives on the topic and are actively connected to the communities of potential participants. Please indicate the primary contact person and the organizers who will attend the workshop. Also, please provide a list of other workshops or tutorials organized by workshop organizers in the past.
• Workshop program committee: Names and affiliation of the members of the (tentative) workshop program committee that will evaluate the workshop submissions.
• Participants: Include a statement of how many participants you expect and how you plan to invite participants for the workshop or tutorial. If possible, include the names of at least 10 people who have expressed interest in participating in the workshop or tutorial.
• Workshop or Tutorial activities: A brief description of the format regarding the mix of events or activities, such as paper presentations, invited talks, panels, demonstrations, teaching activities, hands-on practical exercises, and general discussion. Please also list here any materials you will make available to tutorial participants, such as slides, access to hardware or software, and handouts.
• Planned outcomes of the workshop or tutorial: What are you hoping to achieve by the end of the workshop or tutorial? Please list here any planned publications or other outcomes expected.
• Length: Full-day or half-day. For tutorials, we are also interested in quarter-day proposals (roughly 1.5 hours).
Submission Platform
• All materials must be submitted electronically to PCS 2.0 http://new.precisionconference.com/~sigchi by the proposal submission deadline.
• 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 2026", and then "IUI 2026 Workshops" or “IUI 2026 Tutorials”, respectively, and press "Go".
We encourage both researchers and industry practitioners to submit workshop proposals. To support diverse perspectives in the workshops, we strongly recommend including organizers from varied institutions and backgrounds.
Furthermore, we welcome workshops with an innovative structure that can attract diverse types of contributions and foster valuable interactions.
Prospective organizers are encouraged to contact the Workshop and Tutorial Chairs in advance (workshops2026@iui.acm.org) to discuss ideas, receive feedback, or seek assistance in preparing engaging proposals. Especially for workshop proposals featuring innovative interactive formats, we are happy to help further develop and implement the ideas.
