Message from the Late Breaking Works Chairs
The Late-Breaking Works (LBWs) track provides the CHI community with an opportunity to present new and exciting contributions that showcase innovative technologies, extend prior research conversations, detail short self-contained studies, or provide provocations for new work and ideas to emerge. We welcome submissions around a diversity of topics and methodologies. Examples might include:
- An original and innovative technology, technique, or prototype with or without an accompanying evaluation
- A short qualitative or quantitative study with a complete analysis
- A “sequel” to a prior research contribution
- A “prequel” to motivate or provoke novel conversations or future work
- A theoretical or methodological contribution that provokes novel conversations for the discipline
We encourage all members of the CHI community and newcomers to submit Late-Breaking Works to elicit useful feedback, foster discussions, and share valuable and original ideas at the conference.
All LBW submissions are semi-archival. Authors may re-use and re-submit the content to other peer-reviewed venues (e.g., could be reused in a future CHI full paper submission).
ACM’s Publication Policies
It is critical that authors review ACM’s publications policies. Please read this separate page for them.
Preparing and Submitting Your Late Breaking Work
A Late Breaking Work must be submitted via the PCS Submission System. The submission must have a paper, and can include an optional appendix.
- Paper: The primary submission material consists of an extended abstract in the ACM Master Article Submission Templates (single column; up to 8 pages, excluding references).
- Appendix (optional): The page limit for the appendix is 10 pages. However, note that information that is essential to the understanding of the paper should not be in the appendix (e.g. study protocol, statistical analysis, etc.).
- Supplementary material that is not needed to get a good understanding of the paper, but may provide additional details, e.g. for replication. That kind of material may be included in the supplementary material part (not in the main paper) and as such do not count towards the page limit. Please keep in mind that reviewers are not expected to have to check the supplementary material to get a good understanding of the potential study, analysis or results.
Metadata Integrity
All submission metadata, including required fields in PCS like author names, affiliations, and order, must be complete and correct by the submission deadline. This information is crucial to the integrity of the review process and author representation. No changes to metadata after this deadline will be allowed.
Accessibility
Accessible submissions are essential for reviewers and are good practice. Authors are expected to follow SIGCHI’s Guide to an Accessible Submission. If you have any questions or concerns about creating accessible submissions, please contact the Accessibility Chairs at accessibility@chi2025.acm.org early in the writing process (the closer to the deadline, the less time the team will have to respond to individual requests).
Selection Process
LBWs submissions are reviewed through an ACM Reviewed process, and receive light feedback from reviewers. The criteria for evaluation are as follows:
- Contribution of the LBW to CHI 2025: Does this work present research contributions or ideas that will stimulate interesting conversation among CHI attendees?
- Significance: How important is the problem or question that this submission addresses? Is there an audience at CHI that would find this work influential and/or compelling?
- Originality: How does the work build on, or speak to, existing work in the area? Does it make a novel contribution?
- Validity: How well are the chosen methods described and justified within the submission?
- Clarity: How clear, understandable, and targeted is the writing? To what extent does the abstract conform to all formatting requirements and the 8-page limit?
The submission should contain no sensitive, private, or proprietary information that cannot be disclosed at the time of publication. All submissions are considered confidential during review. All rejected submissions will be kept confidential in perpetuity.
If you are not familiar with LBW submissions, you can find previously published extended abstracts on the ACM Digital Library for reference: CHI 2024 Extended Abstracts (see section “SESSION: Late-Breaking Works”).
Upon Acceptance of your LBW
The corresponding author of a conditionally accepted paper has to follow the instructions on preparing and submitting a final version by the Publication-Ready Deadline. If the authors cannot meet these requirements by the Publication-Ready deadline, the venue chairs will be notified and may be required to remove the paper from the program. The publication-ready version has to follow the LaTeX and Word templates from ACM. Should you need technical assistance, please direct your technical query to: publications@chi2025.acm.org.
Video Presentations
All accepted authors are required to upload a video presentation (a presentation video of your accepted work) by the video presentation deadline of Thursday March 13, 2025. See technical requirements for video content at CHI as a guidance for preparing a video presentation. Accepted authors will receive the details of video presentations separately.
If authors fail to submit their video presentations by the deadline, their accepted work would be withdrawn from the ACM Digital Library.
Unlike previous years, CHI 2025 has decided not to collect video previews (30-second videos to show the core idea of your work), so authors do not need to prepare a 30-second video-preview.
At the Conference
At least one author of an accepted submission should register and present their work at CHI 2025 (remote or in-person attendance). Those who cannot attend in-person will have the option to present remotely asynchronously—we strongly encourage authors to present in person to obtain feedback from other in-person attendees. Further instructions regarding the presentation of the work will be shared closer to the conference dates. If authors fail to register for the conference, their accepted work would be withdrawn from the ACM Digital Library.
In-person presenters will be assigned a time and location to present their poster to CHI 2025 attendees. Posters should include (1) the title, authors’ names, and affiliations, (2) a concise overview of the research, (3) clear illustrations of key aspects of their LBW, and (4) a compelling visual design. Posters might also include QR codes to link to online materials (e.g., scenario videos, interactive prototypes). Note that during the poster presentation at the conference we are not able to provide power outlets or any audiovisual/computing equipment.
After the Conference
Accepted Late Breaking Works will be published as CHI Extended Abstracts in the ACM Digital Library.
