ABSTRACT
In this paper, we describe the formatting requirements for SIGCHI Conference Proceedings and offer a number of suggestions on writing style for the worldwide SIGCHI readership. Please note that some formatting details have changed relative to previous years. These include: a requirement to add ACM DL indexing information; the formatting of table captions and the formatting of references. Please review this document even if you have submitted to SIGCHI conferences before. There are small differences in how the copyright information is presented for extended abstracts and an alternative template is presented elsewhere.

INTRODUCTION
The Proceedings and Extended Abstracts are the records of the conference. The Proceedings  have a slightly different status to the Extended Abstracts and different copyright. We ask that you use alternative template is presented elsewhere for extended abstracts.
As in previous years, we hope to give the volumes a single, high-quality appearance. To do this, we ask that authors follow some simple guidelines. In essence, we ask you to make your paper look exactly like this document. The easiest way to do this is simply to download a template from [5], and replace the content with your own material.  This template file contains specially formatted styles (e.g., Normal, Heading, Bullet, Table Text, References, Title, Author, Affiliation) that will reduce your work in formatting your submission.
PAGE SIZE and columns
All material on each page should fit within a rectangle of 18 x 23.5 cm (7 x 9.25 in.), centered on a US letter page, beginning 1.9 cm (.75 in.) from the top of the page, with a .85 cm (.33 in.) space between two 8.4 cm (3.3 in.) columns.  Use the same proportions of text area (18 x 23.5 cm.), centered, on an A4 page.
Subsequent Pages
For pages other than the first page, start at the top of the page, and continue in double-column format. Right margins should be justified, not ragged. The two columns on the last page should be of equal length.
TYPESET TEXT
Prepare your submissions on a typesetter or word processor.  Please note that page formats may change depending upon the printer that you have specified.  The pages in this file were arranged for printing to Adobe Acrobat PDF Writer.  In this page layout, Figure 1 appears at the top of the left column on page 2, and Table 1 appears at the top of the right column on page 2.  You may need to reposition the figures if your page layout or PDF-generation software is different.
Normal or Body Text
Please use a 10-point Times Roman font, or other proportional font with serifs, as close as possible in appearance to Times Roman, in which these guidelines have been set. The goal is to have a 10-point text, as you see here, using the Normal Style in this template file. Please use sans-serif or non-proportional fonts only for special purposes, such as source code text. The Press 10-point font available to users of Script is a good substitute for Times Roman. If Times Roman is not available, try the font named Computer Modern Roman. On a Macintosh, use the font named Times.
Title and Authors
The title (Helvetica 18-point bold; use Arial if Helvetica is not available), authors’ names (Times Roman 12-point bold) and affiliations (Times Roman 12-point) run across the full width of the page – one column 17.8 cm (7 in.) wide (note that Author and Affiliation are defined Styles in this template file). See the top of this page for two names with different addresses. If only one address is needed, center all address text. For two addresses, use two centered tabs, and so on. We have used a table with invisible borders. Previous versions of this document used centered tabs. What matters is the visual outcome. For more than three authors, you may have to improvise.  Please use full international addresses and telephone dialing prefixes.  Leave one 10-pt line of whitespace below the last line of affiliations.
Abstract and Keywords
Every submission should begin with an abstract of about 150 words, followed by a set of keywords. The abstract and keywords should be placed in the left column of the first page under the left half of the title. The abstract should be a concise statement of the problem, approach, and conclusions of the work described.  The abstract should clearly state the paper's contribution to the field of HCI.
The first set of keywords will be used to index the paper in the proceedings. The second set are used to catalogue the paper in the ACM Digital Library. The latter are entries from the ACM Classification System [1] Please look at this url http://www.acm.org/class/how_to_use.html. In general, it should only be necessary to pick one or more of the H5 subcategories.
First Page Copyright Notice
Leave 3 cm (1.25 in.) of blank space at the bottom of the left column of the first page for the copyright notice. In this template a floating text box will automatically generate the required space.  Note however that the text box is anchored to the ABSTRACT heading, so if that heading is deleted the text box will disappear as well

Figure 1. Figure captions should appear centered, below the figure.

References and Citations
Use a numbered list of references at the end of the article, ordered alphabetically by first author, and referenced by numbers in brackets [1,3,5]. For papers from conference proceedings, include the title of the paper and an abbreviated name of the conference (e.g., for CHI 2002 proceedings, use Proc. CHI 2002). Do not include the location of the conference or the exact date; do include the page numbers if available. See the examples of citations at the end of this document. For conferences that are part of CHI Letters (CHI,UIST,CSCW) use the CHI Letters citation standard [4]. Within this template file, use the style named References for the text of your citation.
References should be published materials accessible to the public. Internal technical reports may be cited only if they are easily accessible (i.e. you can give the address to obtain the report within your citation) and may be obtained by any reader. Proprietary information may not be cited. Private communications should be acknowledged, not referenced  (e.g., “[Robertson, personal communication]”).
SECTIONS
The heading of a section should be in Helvetica 9-point bold in all-capitals (Heading 1 Style in this template file). Use Arial if Helvetica is not available. Sections should not be numbered. 
Subsections
The heading of subsections should be in Helvetica 9-point bold with initial letters capitalized (Heading 2). (Note: For sub-sections and sub-subsections, a word like the or a is not capitalized unless it is the first word of the heading.)
Sub-subsections
The heading for sub-subsections should be in Helvetica 9-point italic with initial letters capitalized (Heading 3). 

Objects	Caption – pre-2002	Caption – 2003 and afterwards	
Tables	Above	Below	
Figures	Below	Below	
Table 1. Table captions should be placed below the table.

FIGURES/CAPTIONS
Place figures and tables at the top or bottom of the appropriate column or columns, on the same page as the relevant text (see Figure 1). A figure or table may extend across both columns to a maximum width of 17.78 cm (7 in.).
Captions should be Times New Roman 9-point bold (Caption Style in this template file).  They should be numbered (e.g., “Table 1” or “Figure 2”). Please note that the words “Table” and “Figure” should be spelled out (e.g., “Figure” rather than “Fig.”). Figure captions should be centered beneath the image or picture. Position the caption below the table just as for Figures.
Color figures must be provided on separate pages at the end of the manuscript and are included in the page count. Paper acceptance does not guarantee publication of a color figure. 
The paper may be accompanied by a short video figure up to two minutes in length. However, the paper should stand on its own without the video figure, as the video may not be available to everyone who reads the paper. Acceptance of a paper does not guarantee acceptance of a video figure.
Inserting Images
Occasionally, MS Word generates larger-than-necessary PDF files when images inserted into the document are manipulated in MS Word. To minimize this problem, resize the image at the appropriate printing resolution (usually 300 dpi) in an image editing tool, and then insert the image into Word using the “insert” menu and the “picture” option.
Table Style
The text of the tables will format better if you use the special Table Text style (in this template file).  If you do not use that style, then you may want to adjust the leading of the text in the tables. (In Word, use Format | Paragraph… then the Line and Page Breaks tab.  Generally, text in tables will look better if it has equal amounts of leading above and below each line.)
LANGUAGE, STYLE AND CONTENT
The written and spoken language of SIGCHI is English. Spelling and punctuation may consistently use any dialect of English (e.g., British, Canadian, US, etc.). Hyphenation is optional. To ensure suitability for an international audience, please pay attention to the following:
•	Write in a straightforward style. 
•	Try to avoid long or complex sentence structures. 
•	Briefly define or explain all technical terms that may be unfamiliar to readers.
•	Explain all acronyms the first time they are used in your text – e.g., “Digital Signal Processing (DSP)”.
•	Explain local references (e.g., not everyone knows all city names in a particular country).
•	Explain “insider” comments. Ensure that your whole audience understands any reference whose meaning you do not describe (e.g., do not assume that everyone has used a Macintosh or a particular application).
•	Explain colloquial language and puns. Understanding phrases like “red herring” requires a cultural knowledge of English. Humor and irony are difficult to translate.
•	Use unambiguous forms for culturally localized concepts, such as times, dates, currencies and numbers (e.g., “1-5- 97” or “5/1/97” may mean 5 January or 1 May, and “seven o’clock” may mean 7:00 am or 19:00).  For currencies, indicate equivalences – e.g., “Participants were paid 10,000 lire, or roughly $5.”
•	Be careful with the use of gender-specific pronouns (he, she) and other gendered words (chairman, manpower, man-months). Use inclusive language (e.g., she or he, they, s/he, chair, staff, staff-hours, person-years) that is gender-neutral. See [4] for further advice and examples regarding gender and other personal attributes.
•	If possible, use the full (extended) alphabetic character set for names of persons, institutions, and places (e.g., Grønbæk, Lafreniére, Sánchez, Universität, Weißenbach, Züllighoven, Århus, etc.).  These characters are already included in most versions of Times, Helvetica, and Arial fonts.
Page Numbering, Headers and Footers
Please submit your anonymous version for reviewing with page numbers centred in the footer. These will be removed in the finals version as page numbers, headers, and footers will be added by the conference printers.
Producing and testing PDF files
We recommend that you produce a PDF version of your submission well before the final deadline. Besides making sure that you are able to produce a PDF, you will need to check that (a) the length of the file remains 8 pages or less, (b) the PDF file size is 4 megabytes or less, and (c) that the file can be read and printed using Adobe Acrobat Reader. 
Test your PDF file by viewing or printing it with the same software we will use when we receive it, Adobe Acrobat Reader Version 5. This is widely used and available at no cost from [2] Note that documents containing non-North American or non-European fonts (e.g. Asian fonts) can not be read with the version of Acrobat that will be used by most reviewers. Please do not use Asian fonts, and verify this by testing with a North American/European version of Acrobat reader (obtainable as above). Something as minor as including a space or punctuation character in a two-byte font can render a file unreadable. 
Blind Review
Some conferences require a particular form of “blind review,” in which the author removes all information that might identify the author’s identity and/or the author’s institution.  If the conference you are submitting to requires blind review, please delete your name and address from the first page of the paper.  You may also need to remove part or all of the Acknowledgments text. Please do not attempt to obscure your name in the References section if you cite your own work. Of course, you will be expected to restore all of the obscured information if your paper is accepted.
Conclusion
It is important that you write for the SIGCHI audience.  Please read previous years’ Proceedings to understand the writing style and conventions that successful authors have used.  It is particularly important that you state clearly what you have done (not merely what you plan to do), and how your work is different from previously published work – i.e., what is the unique contribution that your work makes to the field?  Please consider what the reader will learn from your submission, and how your work will be useful to the reader.  If you write with these questions in mind, your work is more likely to be successful, both in being accepted into the Conference, and in influencing the work of our field.
