Authors are strongly encouraged to include a brief summary (abstract) of their work in the first section of their submission after the title, authors, and affiliation information on the first page. See page 1 of the ACM-CHI12 sample pdf.

Authors are strongly encouraged to include all works cited in their work/submission in a References section at the end of the paper or extended abstract. See page 6 of the ACM-CHI12 sample pdf.

ACM Classification Keywords

The above Author Keywords and ACM Classification Keywords are mandatory by ACM on the first page of your submission after the Abstract text. See page 1 of the ACM-CHI12 sample pdf, how these 2 sections should appear on your submission.

Click here for information on the ACM Computing Classification Scheme.

The ACM Classifiications Keywords (known as "Classifiers" on the PCS submission page) are automatically extracted by PCS from your submitted pdf when you submit. These classifiers MUST appear on the first page of your PDF so they can be extracted properly.

For example: H.5.2 [Information Interfaces and Presentation]: User Interfaces - Interaction styles;

It's very important to follow this format in your paper (please note the placement of the colon, hyphen, and trailing semicolon above).

ACM General Terms are no longer required for the Papers & Abstracts to be included in the ACM Digital Library. This non-mandatory section may be removed from the first page prior to submitting your final version.

Be sure you do not have bad page breaks or bad column breaks. One example of a bad column break is a ‘widow.”
A “widow” occurs when the last line of a paragraph that begins at the bottom of one column appears by itself at the top of the next column). If this happens, tighten the previous column to bring it back, or force an additional line of text over to the next column.
Also make sure that Section and Sub-section heads have at least 2 lines of body text below them when they appear at the end of a page or column.

These are recommendations to ensure good print reproduction of your images, figures, and illustrations utilized in your submission.

(a) Colors and Black & White (Gray Scale) Print Testing. If you have any images in color, please print your paper out in black and white to ensure that the tones and screens used in your images or figures reproduce well in black and white, too. However, your images will appear in full color in the distributed electronic proceedings and in the ACM digital library.

(b) Resolution & CMYK: Images in your document should be at least 300 or 600 dpi for quality reproduction and saved as .tif images (or other compatible format that supports print quality resolution). When creating or revising your images for inclusion in the paper, we recommend choosing CMYK (and not RGB) as the color profile.

(c) TIF (EPS) vs JPG (JPEG) images: TIFs are preferred for press applications where quality takes priority over file size. When TIFs are compressed (LZW compression option when saving out of Photoshop, for example), no image data is lost, thus ensuring maximum quality. A JPEG is a compressed image format designed to keep the file size small, which makes it ideal for use in web graphics.To do this, the JPEG format actually deletes image data from the image. The higher the level of compression, the more data is removed. This is referred to as a lossy compression system. On a printout, the removed data tends to show up as blocky areas of a solid color. At higher resolutions (a minimum of 200 dpi), there's usually enough data in the JPEG file for the compression artifacts to be very noticeable.

(d) Rules/Lines: Rules used in your graphs, tables or charts must be at least 0.5+ pt. and black for quality reproduction. Finer lines and points than this will not reproduce well, even if you can see them on your laser printed hardcopy when checked -- your laser printers have a far lower resolution than the imagesetters that will be used.

(e) Fonts: If your figure uses custom or any non-standard font, the characters may appear differently when printed in the proceedings. Remember to check your figure creation to ensure that all fonts are embedded or included in the figure correctly. Be sure that your images do not contain any Type 3 fonts.

(f) Transparencies: If a figure or image is assembled from multiple images, the images must be embedded, layers flattened or grouped together properly in the file, not lined. Transparencies need to be flattened.

Your final submission MUST NOT contain any footer or header string information at the top or bottom of each page, nor any page numbering. The submissions will be paginated in a determined order by the chairs and page numbers added to the PDF during the compiling, indexing, and pagination process.

It is the contact or submitting author's responsibility to be sure that any funding or special contribution acknowledgements are included in the final version submitted as required by any research, financial, or other grants received (by using the Acknowledgements section before the References section). See page 5 of the ACM-CHI12 sample pdf.

Your PDF file must be ACM Compliant to include in the Digital Library. The requirements for an ACM Compliant PDF are Outlined Here.
Right Click here to obtain the (acm.joboptions) to use ACM distiller settings for full versions of Adobe Acrobat and Distiller ONLY. The acm.joboptions has all the settings and requirements to create an ACM compliant PDF with Adobe Acrobat-Distiller.

Auxiliary material is "optional" for submissions. Your auxiliary material may include information like a technical report with additional details, source code for software, source code for automated theorem provers, test data, or anything else relevant and approved by the CHI'12 chairs.

Authors submitting auxiliary material must also provide a readme text that explains the material contained within the .zip. For example, what file types are included, the software needed to view/execute the files, as well as any other relevant text/information explaining how the auxiliary material relates to the submission.

This read me text supporting your auxiliary material will need to be cut and pasted into the appropriate field on the PCS submission page.

Your Title Must be in Initial Caps & Match the Title that Appears in the Files you are Submitting

This information will automatically be filled in on the PCS submission page from the authors’ PCS account profiles. Please review every author’s name and information to make sure it has the correct spelling and accents. Please note that the author order, author names, and author affiliations in your PDF MUST MATCH what appears on the PCS submission page.

Cut and paste the abstract text from your source document into the abstract field on the PCS submission page (not from your pdf). The abstract on the submission page is the one that will appear in ACM Digital Library associated with your paper and must match the abstract text that appears on page 1 of your submission.

Authors should include the references in their submission per the instructions above.

The PCS submission system is set up to automatically extract the references from your submitted pdf. Please verify that the references have been correctly filled in from your pdf.
NOTE: If you change the references when you submit a revised pdf, erase all the text in this box before submitting the new PDF file. Otherwise, the system will keep your original references.

ACM Classifications

The above Author Keywords and ACM Classification Keywords are mandatory by ACM on the first page of your submission after the Abstract text, per the instructions above.

The ACM Classifiications Keywords (known as "Classifiers" on the PCS submission page) are automatically extracted by PCS from your submitted pdf when you submit. These classifiers MUST appear on the first page of your PDF so they can be extracted.

Leave this field empty on the PCS submission page for PCS to fill in automatically from your PDF file. Return to PCS to verify the system has automatically captured your primary and any additional ACM classifiers separately, as well as accurately matches those that appear on your submitted pdf. Your paper should have ACM Classifications in the standard form.

For example: H.5.2 [Information Interfaces and Presentation]: User Interfaces - Interaction styles;

It's very important to follow this format in your paper (please note the placement of the colon, hyphen, and trailing semicolon above). Otherwise, the PCS system will not be able to automatically extract the ACM Classifications (as separate primary and additional classifications) from your PDF file.

Auxiliary Material (optional):
You can included auxiliary material as part of your submission, if this was reviewed as part of your original submission. This must be a single zip file that contains all of the auxiliary materials and a read-me text file, per the instructions.

This brief statement of your work is to be included in the Final Program ONLY and does not need to appear within the body content of your submission's pdf. You will see the appropriate field on the PCS submission page after the fields to submit the required files associated with your work.

The Contribution & Benefits statement is 30 words or less. This statement will appear in the conference program and will be used by attendees to determine whether they will attend your talk. It concisely describes the contribution made by your paper or note to HCI and the benefit that readers can gain from it. The Contribution & Benefit is most typically stated in two sentences, the first sentence making clear what type of contribution (technique, system, guideline, etc.) is presented and the second describing the class of problems that the contribution addresses. Click here to obtain examples of contribution & benefit statements.
