June 8-11, 2026

Göteborg, Sweden

Deadline: March 30, 2026

ACM UMAP is the premier international conference that brings together research in AI and HCI to support effective human-AI collaboration via interactive systems that can model, adapt, and personalize to their users. The conference is sponsored by ACM SIGCHI and SIGWEB User Modeling Inc., as the core Steering Committee oversees the conference organization. UMAP operates under the ACM Conference Code of Conduct.

ACM UMAP 2026 invites Late-Breaking Results (LBR) papers as well as Demonstrations (demos) of innovative UMAP-based systems (including research prototypes). The topics for these submissions are the same as the ones included in the Call for Full and Short Papers. However, their scope, timing, and length are different. In particular, the maximum length of LBR papers is shorter than that of short papers from the main track. More importantly, LBR papers are expected to present innovative ideas that are still being explored and have shown some promising results. The track is also a dissemination channel for new research directions. Mature results that have already undergone extensive experimental validation are more suitable for the general call, either as a full or short paper. Note that LBR papers are also to be presented in person at the conference in poster format, allowing for more informal discussion of the ideas shared.

Demos are intended to present systems relevant to the UMAP conference. These should either have been used to achieve the research outcomes presented as full and short papers, or currently be used as a platform for future research. As such, we highly recommend authors of accepted full and short papers to also prepare a submission for a demo of their system to be showcased at the conference in the LBR and Demo session.

Important Dates

• March 30, 2026 - Submission
  
• April 21, 2026 - Notification of Acceptance
  
• April 28, 2026 - Camera-ready Submission (TAPS system)
  

Note: the submission deadline is at 11:59 pm AoE (Anywhere on Earth) time.

Submission

All submissions must be written in English. They should be submitted electronically, in a PDF format, through the EasyChair submission system, https://easychair.org/my/conference?conf=umap2026, by selecting the “UMAP26 Late Breaking Results and Demo Papers” track and, subsequently, choosing the specific format (LBR or demos).

Late-Breaking Results Format

Page Limit. Up to 4 pages, including references (figures, tables, proofs, appendices, acknowledgments, and any other content count toward the page limit).

Proceedings. Publication in the ACM UMAP 2026 main proceedings. Please note that LBR papers will be exempt from the ACM Open APCs (Article Processing Charges), as they fall under the “work in progress” category.

Presentation format. Presented in-person (physically) as a poster during the conference.

Description. LBRs are research-in-progress that must contain original and unpublished accounts of innovative research ideas and preliminary results, addressing both the theory and practice of UMAP. In addition, papers introducing recently started research projects or summarizing project results are welcome. We encourage researchers and practitioners to submit late-breaking work as it provides a unique opportunity for sharing valuable ideas, eliciting useful feedback on early-stage work, and fostering discussions and collaborations among colleagues.

In case papers rejected in the main track (i.e., submitted as full or short papers) are submitted to this track, they should be revised. On the one hand, they should take into account the comments made to help improve the paper. On the other hand, they should also fulfill the scope of the LBR, which emphasizes the novelty of ideas. This is also valid for papers that have been recommended as an LBR when rejected in the main track.

Demos Format

Page Limit. Up to 3 pages, including references and all other content (figures, tables, proofs, appendices, acknowledgments, etc.). On an extra page (not to be published), submissions should include a specification of the technical requirements for demonstrating the system at UMAP 2026.

Supporting Material. Video or external material demonstrating the system.

Proceedings. Publication in ACM UMAP 2026 main proceedings. Please note that Demo papers will be exempt from the ACM Open APCs (Article Processing Charges), as they fall under the “Demonstration” category.

Presentation format. Presented in-person (physically) as a demo, plus as a poster during the conference.

Description. Demos will showcase research (system) prototypes, industry showcases, and commercially available products in a dedicated session. Demo submissions must be based on an implemented and tested system that pursues one or more innovative ideas in the interest areas of the conference. Demonstrations are an excellent and exciting way to showcase implementations and receive valuable feedback from the community, especially for those papers that have been presented in the main track. Each demo submission must make clear which aspects of the system will be demonstrated, and how these will be demonstrated on-site as well as online.

To better identify the value of demos, we also encourage authors to submit a pointer to a screencast (max. 5 minutes on Vimeo or YouTube) or any external material related to the demo (e.g., shared code on GitHub).

More Details

Non-Anonymity

Submissions for both LBR and demos will be reviewed single-masked (i.e., authors’ names must be included in the papers), thus there is no need to anonymize before submission.

Template

Following the ACM Publication Workflow, the proposal should be arranged based on the new ACM two-column format. Instructions for the organizers are given below:

• LaTeX (use \documentclass[review,sigconf]{acmart} in the sample-authordraft.tex file for two-column). Please carefully follow the ACM’s instructions for preparing your article with LaTeX.
  
• Overleaf (use \documentclass[review,sigconf]{acmart} for two-column). Please carefully follow the ACM’s instructions for preparing your article with Overleaf.
  
• Word. Please carefully follow the ACM’s instructions for preparing your article with Microsoft Word, ignoring the single-column instructions and the single-column submission template. Please use the double-column Word template.
  

Should you have any questions or issues going through the instructions above, please contact support at acmtexsupport@aptaracorp.com for LaTeX and Microsoft Word inquiries.

Accessibility

Authors are strongly encouraged to provide “alt text” (alternative text) for floats (images, tables, etc.) in their content so that readers with disabilities can be given descriptive information for these floats that are important to the work. The descriptive text will be displayed in place of a float if the float cannot be loaded. This benefits the author, and it broadens the reader base for the author’s work. Moreover, the alt text provides in-depth float descriptions to search engine crawlers, which helps to properly index these floats. Additionally, authors should follow the ACM Accessibility Recommendations for Publishing in Color and SIG ACCESS guidelines on describing figures.

Submission Policy

All submissions and reviews will be handled electronically. ACM UMAP has a no dual submission policy, which is why submitted manuscripts should not be currently under review at another publication venue. Particularly, please consider the following ACM’s publication policies:

• “By submitting your article to an ACM Publication, you are hereby acknowledging that you and your co-authors are subject to all ACM Publications Policies, including ACM’s new Publications Policy on Research Involving Human Participants and Subjects. Alleged violations of this policy or any ACM Publications Policy will be investigated by ACM and may result in a full retraction of your paper, in addition to other potential penalties, as per ACM Publications Policy.” https://www.acm.org/publications/policies/research-involving-human-participants-and-subjects
  
• “Please ensure that you and your co-authors obtain an ORCID ID, so you can complete the publishing process for your accepted paper. ACM has been involved in ORCID from the start, and we have recently made a commitment to collect ORCID IDs from all of our published authors. We are committed to improving author discoverability, ensuring proper attribution, and contributing to ongoing community efforts around name normalization; your ORCID ID will help in these efforts.”
  

Review Process & Camera-ready Submission

Review 

Submissions will be reviewed by at least two independent reviewers. They will be assessed based on their originality and novelty, potential contribution to the research field, potential impact in specific use cases, usefulness of presented experiences, and their overall readability. Papers that exceed the page limits or do not adhere to the formatting guidelines will be returned without review.

The ACM Code of Ethics gives the UMAP program committee the right to (desk-)reject papers that perpetuate harmful stereotypes, employ unethical research practices, or uncritically present outcomes/implications that clearly disadvantage minority communities. Further, reviewers will be explicitly asked to consider whether the research was conducted in compliance with professional ethical standards and applicable regulatory guidelines. Failure to do so could lead to a (desk-)rejection.

Camera-ready Information

Accepted papers will be subject to further revision to meet the requirements of the camera-ready format required by ACM. We strongly recommend the use of LaTeX/Overleaf for the camera-ready papers to minimize the extent of reformatting. Users of the Word template must use either the version for Microsoft Word for Windows, Macintosh Office 2011, or Macintosh Office 2016 (other formats, such as Open Office, etc., are not permitted) for the camera-ready submission to avoid incompatibility issues.

Instructions for preparing the camera-ready versions of accepted papers will be provided after acceptance. This might include instructions to prepare a video of the accepted contribution. Camera-ready versions of accepted papers will be later submitted using ACM’s new production platform, where authors will be able to review PDF and HTML output formats before publication.

In-person attendance policy and Open Access

Each accepted contribution must be presented in person to be included in the conference proceedings. All UMAP 2026 papers will be published under ACM Open. 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.

During the conference, all categories will be presented at the poster reception, in the form of a poster and/or a software demonstration, following the poster format. This form of presentation will provide presenters with an opportunity to obtain direct feedback about their work from a wide audience during the conference.
