Once you have received your notification acceptance, there are some steps you have to complete to prepare your final submission for publication. All conference venues that publish papers and extended abstracts in the ACM Digital Library will follow this process.  If you have questions, please contact the templates chairs (templates@chi2021.acm.org). (This page is a tailored version of Final Submission Author Instructions for SIGCHI Conferences)

ACM e-Rights

After notification, you will receive an email from the ACM e-Rights system to begin the publication process for your paper. Please complete the e-Rights form before you upload your final submissions.

• The e-Rights form will only be sent to the contact author, so it is important that this person is able to respond to emails and complete the form.
• This email will come from rightsreview@acm.org. Please remain alert for this email after your acceptance notification, as it may be sent to spam.
• Ensure that the paper title, author names, and emails are exactly how you want them to appear on your final publication. If there is a mismatch between this information and the one provided in source file, you may have the same mismatch between the PDF and HTML of your paper; as the information provided in your e-Rights form is not only used to validate the metadata of your publication source, but is also used in the HTML version of your paper. Any mismatches could delay the publication of your paper. If you need to change the information, please contact the technical program co-chairs (tpc@chi2021.acm.org) to get approval.

Final Materials for Publication in PCS

Please upload your final materials for publication to PCS in the following format before the deadline.

Document Source for Publication (Required)

Document source file of your submission. The source file(s) for your submission (.docx file or .zip archive of LaTeX source). The final PDF which will be generated from the source file.

Video Preview (optional)  

For details please see Video Preview.

Video Preview Captions (required if the video contains spoken dialog)

Subtitle file in .srt or .sbv format. A manually created caption file is strongly recommended as automatically generated captions may contain errors.

Video Figure (optional)  

You may include a video figure as an .mp4 file. Up to 5 min long, maximum 100MB, 1080p (1920x1080) resolution, 16:9 aspect ratio, encoded as MP4 using H.264 codec. See Technical Requirements and Guidelines for Videos at CHI for details.

Video Figure Captions (required if the video contains spoken dialog) 

Subtitle file in .srt format. A manually created caption file is strongly recommended as automatically generated captions may contain errors.

Supplemental Materials (optional)

Supplemental Materials are optional but must be uploaded as a single ZIP file. This material will only appear in the ACM DL. The zip can contain survey material, source code, data, images, additional videos, slides etc. Sharing research material to facilitate replicability is optional but recommended (see Transparency section in CHI's guide to a successful submission). If you submit supplemental materials, a readme file called README.md has to be provided that describes the files included in the zip file. This description should include, for example, the file types contained in the zip file, the software needed (if any) to view/execute the files, and any other relevant information explaining how the supplemental  material relates and supports the ACM submission. If you uploaded supplemental materials, but you did not provide a README.md file, your supplemental material will not appear in the ACM DL. 

Author Generated PDF (optional)

The new publication system (TAPS) will generate the primary pdf for your paper (which you will get a chance to approve), however you can also submit a supplementary ‘author generated’ PDF that you’ve created yourself. Please be aware that this author generated PDF will ONLY be in the supplementary materials section of the Digital Library (and will NOT be retrieved as the primary PDF for the paper).

Approving Your Final Submissions in ACM TAPS

After the final submissions are processed by TAPS, you will receive an email asking you to approve your final version for publication. The link provided will take you to the TAPS Author Dashboard for your paper.

• The TAPS Author Dashboard email will only be sent to the corresponding author, so it is important that this person is able to respond to emails and complete the form.
• This email will come from tapsadmin@aptaracorp.awsapps.com. Please remain alert for this email after you have uploaded your source, as it may be sent to spam.  This may take up to two weeks to arrive depending on the size of the conference and the processing required.
• When you receive an email titled “PDF and HTML Proofs: available for review” please follow the links provided to access the TAPS generated PDF and HTML files.
  • If you approve the proofs, we strongly encourage you to add accessibility and return the accessible pdf to be the published document for the ACM digital library by attaching it in a reply to the original email. For the purpose, you can follow the instructions provided in the email or use the following link https://chi2021.acm.org/for-authors/presenting/papers/making-your-final-pdf-accessible. Your submission is complete and ready for publication in the Digital Library.
  • If you do not approve the proofs, please reply to this email explaining the feedback and modifications that you want in your proofs. This email will be answered by TAPS coordinators, who will get back to you with the revised outputs of your files, till you are satisfied with the generated output and approve it.
  • PDF Proof you receive from TAPS does not yet support automatic integration of accessibility features. Please see the following section for instructions on how you can add accessibility features to your final PDF.

Preparing Your Final Source

All authors should ensure they are using the latest version of the template available on the ACM Templates page.

Accessibility

Authors for SIGCHI Publications must follow the accessibility guidelines on the ACM Templates Page. Ensure all figures and images have suitable figure descriptions.

These accessibility features will go into the HTML version but this is not yet supported in the PDF version generated by TAPS for final publication. We strongly encourage you to add accessibility features to your final PDF as generated by TAPS, detailed instructions are at Making Your Final PDF Accessible page.  Return your accessible pdf by attaching it to a reply to the original email titled "PDF and HTML Proofs: available for review" 

Please be aware that adding these accessibility features to your PDF requires access to Acrobat Pro DC.  If you do not have access to this software, you may not be able to add accessibility features to your final PDF.

Word Authors

At CHI 2021 a vendor will complete the validation of documents submitted using Word source files. Authors do not need to complete validation or use any macros when preparing their final source for CHI 2021. Word authors should follow these instructions. 

• Use a filename that does not contain spaces and special characters.
• Please ensure that ALL content in your Word document is styled with the correct styles as listed in the table provided in the template.
• Use numbered style for Bibliography.
• There are some common issues that can delay the processing of your publication.  Please check for the following in your final version:
  • Ensure elements such as the title, headings, authors, acknowledgements, reference heading, and individual references are styled as described in the template.
  • If a single figure contains multiple images, these must be inserted as a single image.
  • All images/figures are of appropriate quality (to be able to be converted in required formats for HTML version) and must be followed by a caption.
  • Provide alt text (instructions available in the template) for all figures.
  • Remove all blank lines.

ACM's Computing Classification System (CCS) is a taxonomy for the computing field. Authors are expected to select one or more descriptors (or "concepts") from the CCS and add them to your document.

A list of CCS descriptors can be built for your article from https://dl.acm.org/ccs/ccs.cfm. Authors can select one or more descriptors and assign a priority to them.

When a list of CCS descriptors has been built, that information must be added to your document. In Microsoft Word, adding CCS concepts to your document is a two-step process:

• Select the formatted list of concept(s) from the Web interface - here's an example:
  • Computer systems organization~Real-time operating systems
  • paste it into your document, and style with the "CCSDescription" tag.
• Select "view CCS TeX Code" and check the "Show the XML only" box, copy the XML and paste into your Word document in the following location (Mac):
  • select "Properties" from the "File" menu
  • select the "Summary" tab
  • paste the XML into the "Comments" area
• Select "view CCS TeX Code" and check the "Show the XML only" box, copy the XML and paste into your Word document in the following location (Windows):
  • select "Properties" from the "File" menu
  • select "Advanced Properties"
  • select the "Summary" tab
  • paste the XML into the "Comments" area

It is important to perform both parts of this task - inserting the formatted list into the body of your Word document and applying the appropriate style, AND inserting the XML representation of your selected CCS concepts into the metadata of your Word document.

LaTeX Authors

LaTeX source requires some preparation for final submission, please go through the ACM’s LaTeX best practices guidelines available here. Please ensure your source follows these requirements:

• SIGCHI publications use the “sigconf” visual style. This is specified in the document class command. You should use \documentclass[sigconf]{acmart} (removing other tags such as “manuscript”, “authordraft”, “anonymous” and “review”). Please also make sure to use coding of basic elements as per the sigconf sample tex file available with the acmart LaTeX packet.
• All images are of appropriate quality (to be able to be converted in required formats for HTML version)
• SIGCHI publications use the “ACM-Reference-Format” bibliography style.
• Your LaTeX source must have a single “main” .tex file, although you can organise your project with a main .tex file that includes input from multiple .tex files. Please remove all samples and old tex files that include a document class.

• Ensure that your source compiles without errors. Some editors, such as Overleaf, will tolerate errors and generate a PDF, but this is not permissible for final publications. Please check the error log and correct all compilation errors before submitting your final source.
• Ensure that your bibliography compiles without warnings. Accurate bibliographies are required for publication. If your bibliography has missing entries or other errors, your source will not be accepted for publication. Please check the warning log and correct all warnings and errors related to your bibliography before submitting your final source.
• Ensure you check the list of approved packages for LaTeX documents.  If you use a package not listed, you will be required to update your source and this may cause delays to the publication of your work.  Packages can be requested to be added to the list, and you can always contact acmtexsupport@aptaracorp.com if you have questions.
• Provide descriptions (instructions available in the template) for all figures.

Overleaf users can download LaTeX source files in a zip format by clicking the "Menu" button on the top-left corner and then clicking the "Source" icon in the "Download" section. Note that all samples and old tex files need to be deleted (see the above requirements) on Overleaf before downloading the zip file; this can be done by right-clicking each unnecessary file and then selecting the "Delete" option. Authors who need technical support about Overleaf should contact support@overleaf.com.

Green Open Access

All SIGCHI authors are encouraged to archive their work in a “green open access” repository in line with ACM’s Green Open Access Policy. Authors can host their final versions on their own homepage, an institutional repository, a repository mandated by your funder, or a non-commercial repository like arXiv.

• You must archive a version (pdf) created by yourself. You are not allowed to archive the official version (pdf) created by the ACM. 
• Include the DOI assigned once you complete the e-rights form.
