Instructions for Camera-Ready Papers

This year's conference will be completely virtual. At least one author for each paper must register for the conference.

ACM is revising its Publication Workflow and Article Templates for the article submission and publication process. As part of this process, ACM is switching to a single-column manuscript and a camera-ready version format. The purpose of the updated process is to increase the accessibility of articles published in the ACM Digital Library.

The following instructions will help you in formatting the camera-ready version of your IUI paper. Please, read all of them carefully before submitting it. This flowchart summarizes all steps required to complete this process.

General Tips

Please do not email about a missing eRights form until 7 days prior to the deadline for your submission. You can still verify the majority of the other requirements prior to receiving the eRights form and TAPS link.
  1. ACM provide best practice guidelines for the submission process with TAPS:
  2. Have you completed the ACM eRights review form for your submission? As IUI 2021 will be online only, we emphasize that authors should agree to videotaping in the eRights form to attend virtually the conference. If you have not received an email from until a week before your camera-ready submission deadline, check the contact author(s)'s junk or spam email folders and complete the form promptly. If the eRights review form can not be located, email with your Paper ID number, title, and correct contact author's valid email address.
  3. All submissions must comply with the ACM SIG proceedings templates and formatting.
  4. Be sure that all 3rd party material is properly documented. Please review the copyright policy.
  5. If you have questions or problems, please contact the proceedings co-chairs at the following email address:
  6. After completing the eRights form, you will receive an email from with a link through which you can access TAPS. Have you received this email? If not, check the contact author(s)'s junk or spam email folders. If the access link can not be located, email with your Paper ID number, title, and correct contact author's valid email address.
  7. Submit your paper to The ACM Publishing System (TAPS) using the link sent to you by email.

Submission Deadlines

The submission deadlines for the production of the proceedings are:

  • Initial submission to TAPS: February 16th
  • Final submission addressing any TAPS issues: February 23rd

Deadlines refer to 23:59 (11:59 pm) in the AoE (Anywhere on Earth) time zone.

ACM Templates

Your camera-ready submission must be formatted according to the new standard ACM SIG proceedings format. The new format is available here . Further, the authors are required to include a proper classification for the paper according to the ACM Classification System (CCS). Additional information on how to use it is available here .

Word Templates

Please choose the correct version of the ACM Master Article Template depending on the version of Word you are using. Follow the instructions detailed in the ACM Instructions for Applying the Master Article Template document.

Based on how the ACM eRights form was completed, paste the copyright macro you received in the email confirmation for getting the right copyright notice

LaTeX Instructions

Please use the latest version of the Master Article Template – LaTeX to create your submission. You must use the "manuscript" option with the \documentclass[manuscript]{acmart} command to generate the output in a single-column format which is required for a camera-ready submission. Please see the LaTeX documentation and ACM's LaTeX best practices guide for further instructions.

To ensure 100% compatibility with The ACM Publishing System (TAPS), please restrict the use of packages to the whitelist of approved LaTeX packages.

After completion of the ACM eRights form, you will receive another email from which contains the commands that need to be inserted into your final LaTeX file in order to generate the proper rights statement and Bibstrip data.

Please do not enter the page numbers.

Page Limits

The following page limits refer to the single-column format for submission to TAPS. There is a separate page limit on the two-column proof generated by TAPS listed in a section below.
  • Long Paper: 14 pages plus 4 extra pages for references
  • Short Paper: 6 pages plus 2 extra pages for references
  • Student Consortium: 4 pages plus 1 extra pages for references
  • Poster/Demo Papers: 4 pages plus 1 extra page for references
  • Workshop/Tutorial Summaries: 4 pages plus 1 extra pages for references

Paper Metadata

  1. Double-check that your title and abstract fields in the TAPS submission page match the text in your paper.
  2. Be sure that the title is in Initial Caps. Initial Caps Meaning First Letter of the Main Words Should be Made Capital Letters. Capitalize the First Letter of Main Words in the Title (Most Nouns), except a, an, the, conjunctions (and, but, or, for, …), and prepositions (of, to, in, on, …)
  3. Double-check the author's name, affiliation, and email in the paper.

Accessibility Guidelines

While working on your final document, please keep the following in mind:

  1. Published papers must follow the accessibility guidelines presented by ACM on the ACM Templates page.
  2. All images and figures should have text descriptions (“alt text”)
    1. ACM provides general guidance on creating and adding figure descriptions on the Describing Figures for ACM Publications page
    2. You may also reference the SIGACCESS Guide on Describing Figures for additional suggestions regarding figure descriptions.

HTML proofs should support most accessibility features, but TAPS does not yet fully support automatic integration of accessibility features into your PDF proof.

When you receive your proofs for approval, you may update the PDF document with accessibility features and return it by attaching it in a reply to the original email.

For making your PDF accessible, please reference the CHI 2021 guide on Making Your Final PDF Accessible. This guide assumes Adobe Acrobat Pro, so you may be unable to add these features without access to this software.

If you have any questions or are in need of assistance regarding the accessibility guidelines, you may email the Accessibility Chairs at

Camera-Ready Submission

You should submit a single ZIP file containing ALL your source files (e.g., *.tex, *.bib, *.sty, and all figures for Latex Users or the .docx file for Word users). In order to upload these files into TAPS, follow the instructions presented in the following tutorial.

The contact author will receive the 'Notification to upload your paper to the ACM TAPS' email from TAPS, in which the system will ask you to submit your source files and provide a unique link through which you can access TAPS (your specific author dashboard). In the top of your author dashboard TAPS provides the information about "Proceeding Acronym", "Paper ID" and "Title of Paper". You can upload a zip file in TAPS for further processing and the ZIP file naming should be like ProceedingAcronym– It is important to follow strictly all the instructions of file structure and naming of the zip file that should be uploaded on TAPS.

The publishing system produces automatically the traditional PDF output as well as ACM's new responsive HTML5 design. Within 24 hours after submitting the .zip file, the contact author will receive the 'PDF and HTML Proofs: available for review' email notifying that the proofs for the published versions of your paper (both PDF and HTML5 versions) are available for your review and approval. Note that TAPS will generate the output PDF using the double-column format, which follows the "sigconf" proceedings template. TAPS receives the information from ACM's system regarding which composition layout needs to be followed for the papers in your proceedings (i.e., "sigconf" in this case) and applies the required style internally.

If you are satisfied with the proofs for the published versions, please notify us of your approval within The ACM Publishing System (TAPS). If you find that the PDF and/or HTML file(s) did not convert correctly, follow the instructions presented in the author dashboard.

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

Page Limits for PDF Proof of Published Versions

After submitting your source files to TAPS, it will send to you HTML and PDF proofs for the published version, which should be approved by you. The PDF proof will be formatted in double-column, following the sigconf style. As one of the steps for approval, you should check whether the total number of pages of this PDF is in conformance with the page limits listed below, which refer to the double-column format produced by TAPS. It is expected that TAPS will automatically generate a version fitting these page limits. In case your final version ends up slightly over the limit, please work on figure flotation or on the usage of 'vspace' directives in Latex versions. In case of issues going through this process, please contact the proceedings co-chairs at the email address:

Please note these page limits refer to the two-column document generated by TAPS, not the one-column format you will upload to TAPS.
  • Long Paper: 11 pages, including references
  • Short Paper: 6 pages, including references
  • Student Consortium: 3 pages, including references
  • Poster/Demo Papers: 3 pages, including references
  • Workshop/Tutorial Summaries: 3 pages, including references

Publication in the Proceedings

In order to include your paper in the proceedings of the 26th IUI conference and to schedule your presentation in the conference program, at least one of the authors MUST register for the conference. Further, at least one author MUST attend the conference to present the work. Make sure to use your institutional email address when registering (the same email address used in your paper). This will help us showcase speaker profiles alongside their paper in the conference platform.
