Summary of Changes

(For Papers and Notes only)
CHI papers are conditionally accepted. The Associate Chair may insist that certain changes being made - this should have been clearly stated in the meta-review. If this is the case, please summarize how you met those changes here, so the AC can look for them. You are encouraged to enhance your paper in ways other than those called out by the AC.

Preparation Requirements for your Files: Page Size, Bad Breaks, Figures/Images, Page Numbering, PDF, Accompanying Video, and Thumbnail Image

Submissions that do not conform to the ACM SIG standards, templates, and formats will be returned to the author for corrections and/or alterations. The page size for this ACM publication is US Letter (8-1/2x11 inches).

Bad Breaks

Be sure that there are no bad page or column breaks
Meaning no widows (last line of a paragraph at the top of a column). If this happens either tighten the previous column or force a line over.
Section and Sub-section heads should remain with at least 2 lines of body text when near the end of a page or column.

Images & Figures

(a) Colors and Black & White (Gray Scale) Print Testing. If you have any images in color, we suggest that you print your paper to a black/white printer (or black-white version) to be sure that the tones and screens used in your images or figures reproduce well in black and white. Your images will and may appear in color in the electronic proceedings, in color in the ACM Portal (digital library), but in grayscale in any print proceedings.

(b) Resolution & CYMK: We recommend images to be at least 300 or 600 dpi for quality reproduction and saved as .tif images. When creating or revising your images for inclusion in the paper, please be sure you choose CYMK and not RGB (as the color profile choice).

(c) TIF (EPS) vs JPG (JPEG) images: TIFs are preferred for press applications where quality takes priority over file size. While TIFs can be compressed (LZW compression option when saving out of Photoshop, for example), no image data is lost, thus ensuring maximum quality. JPEG was designed as 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: We recommend for quality reproduction of rules in your graphs, tables or charts, that the rules are at least a 0.5 pt. and black. Finer lines and points than this will not reproduce well, even if you can see them on your laser printed hardcopy when.

(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 that all fonts are embedded or included in the figure correctly.

(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 should also be flattened.

Page Numbering, Headers, & Footers

Your final submission SHOULD NOT contain any footer or header string information at the top or bottom of each page. 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.
