Late-Breaking Work

Quick Facts


Important Dates:


New This Year:
Submissions must be anonymous at the time of submission. Submissions with author information will be desk-rejected. We are introducing anonymous reviews to reduce bias and increase fairness in the review process.
The single-column ACM Master Article Submission Template needs to be used instead of the landscape CHI EA template.


Submission Details:

  • Submissions can be made to PCS here: PCS Submission System
  • Template: ACM Master Article Submission Templates (single column). Note that we eliminated the old CHI extended abstract format (landscape) and use the same format as full papers.
  • Submissions must be up to 8 pages long (not including references).
  • Submissions are anonymous and should not include any author names, affiliations, and contact information in the PDF.
  • Authors are strongly encouraged to work on improving the accessibility of their submissions, using recommendations found in the Guide to an Accessible Submission.


Selection Process: Juried


Chairs: Juho Kim, Edward Melcer, Katrin Wolf (


At the Conference: Accepted LBWs will be presented as posters during CHI 2021. Details regarding presentation will be provided with acceptance notifications.


After the conference: Accepted LBWs will be available in the ACM Digital Library.


What are Late-Breaking Works?

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 to submit Late-Breaking Works to elicit useful feedback, while sharing valuable and original ideas and fostering discussions with others at the conference.


How are LBWs reviewed?

LBWs submissions are reviewed through a juried process, and receive light feedback from reviewers. The criteria for evaluation are as follows:

  • Contribution of the LBWs to CHI 2021: Is this a complete piece of research that will stimulate interesting conversation among CHI attendees? Is there compelling reason for this work to be an LBW and not a full research contribution in the next conference cycle?
  • 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?
  • Written Presentation: 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.


What happens after LBWs are accepted?

Authors of accepted submissions will receive instructions via email regarding how to prepare and submit their publication-ready versions and video previews, as well as details on the logistics of poster presentation at CHI 2021. All authors are strongly encouraged to use the instructions for accessible pdfs to add accessibility to your final generated pdf. Accepted LBWs will be made available in the ACM Digital Library two weeks before CHI. Details follow.


Publication-ready versions: Authors of accepted submissions will receive short feedback on changes to be made to their LBWs for the publication-ready deadline. They are encouraged but not required to make edits to their submissions before submitting publication-ready versions of the same.


Video previews: Authors of accepted submissions will be asked to submit a 30-second video preview summarizing the paper; this is optional, but highly encouraged, as it will increase the visibility of the work before and at the conference, and in the ACM digital library in perpetuity. See here for technical requirements and guidelines for videos at CHI. Keep in mind the deadline for submitting your video preview. Video previews count towards the total submission size of 100MB, so we recommend that the publication-ready submission not exceed 80MB.


Poster presentations: Authors will be assigned a time and location to present their poster to CHI 2021 attendees, potentially over two consecutive days. Posters should include (1) the title, authors’ names, and affiliations, (2) a concise overview of the research, (3) clear illustrations of key aspects of the LBWs, and (4) a compelling visual design. Posters might also include QR codes to link to online materials (e.g., scenario videos, interactive prototypes). At the conference, no power outlets, nor any audiovisual/competing equipment will be provided. At least one author must be in attendance to present the poster.


Inclusion in the ACM Digital Library: 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 CHI 2021. The official publication date affects the deadline for any patent filings related to published work. Late-Breaking Works acceptances whose authors are not at the conference to present their poster may be withdrawn from the ACM Digital Library. Copyright is retained by the authors, and the material from them can be used as the basis for future publications as long as there are “significant” revisions from the original. For more information on the republishability of material appearing at CHI, along with links to relevant ACM policies, please see the section on Republishability on the main CHI CfP.
