Sigchi Modern

%% SIGCHI Proceedings Format (modern) Sample Document
%% This sample file demonstrates the use of the `sigchi-modern' class file.
%%
%% The content of this document draws heavily on the `HCI Archive Format'
%% template supplied by SIGCHI, but has been modified to demonstrate and
%% document the LaTeX class.

% The parameter given to the `\documentclass' command can be one of:
%   `preprint', `submission', or `final'.
% These control the presence of certain features for each stage of the authoring
% process. For example, `submission' does not output the author block, and
% `final' disables page numbers.
%
% The \preprintonly{}, \submissiononly{}, and \finalonly{} commands allow you
% to wrap text that will only be output under the corresponding option.
\documentclass[preprint]{sigchi-modern}

% These packages aren't required, but do provide some helpful features that are
% used in this sample.
\usepackage{graphicx}  % Graphics for figures
\usepackage{booktabs}  % Nice formatting for tables
\usepackage{balance}   % Attempts to balance the columns on the last page

% A nice way to help avoid overful lines handing out into the margins is the
% `microtype' package, which lets certain characters extrude a *little* bit.
\usepackage{microtype}
% If the situation becomes dire, use:
%\sloppy

% You may use any bibliography package as long as the output matches that of
% the prescribed format. `natbib' is a fairly nice default, and the provided
% BibTeX style file has been tested with it.
\usepackage[numbers,sort&compress]{natbib}
\bibliographystyle{../bibtex/acm-sigchi-modern}

% Define these tokens as appropriate for the conference to generate the
% necessary copyright notice for `final` mode.

\section{Introduction}
This format is to be used for submissions to SIGCHI conference proceedings. We
wish to give this volume a consistent, high-quality appearance, and therefore
ask that authors follow some simple guidelines. In essence, you should format
your paper exactly like this document. The easiest way to do this is to use the
source of this document as a template, and replace the content with your own
material.

\subsection{\LaTeX\ Document Class}
The \LaTeX\ document class, \texttt{sigchi-modern}, will format your source
using the guidelines in this paper (except the editorial guidelines, of course).
The document class is also fairly configurable, and contains many conveniences
for correctly formatting figures, references, author lists, section headings,
etc. Unless noted, the formatting requirements detailed in this document (fonts,
spacing, layout, etc.) will be applied automatically when using the \LaTeX\ 
document class.

The class operates in one of three modes: \texttt{preprint},
\texttt{sub\-mis\-sion}, or \texttt{final}. The mode is set in an option to the
\texttt{\textbackslash documentclass} command and toggles the output of
features for each stage of the authoring process (e.g., \texttt{preprint} shows
coloured hyperlinks and formatting guides, and \texttt{submission} hides the
authorship information).

\section{Page Size and Columns}
On each page, your material (not including the page number) should fit within a
rectangle of 18 $\times$ 23.5 cm (7 $\times$ 9.25 in.), centred on a \textit{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. Right margins should be
justified, not ragged.

\section{Typesetting Text}
Use 10-point Times for the body text; only use other fonts for special
purposes, such as headings (sans-serif) or source code (monospace).

\subsection{Title and Authors}
Your paper's title, authors, and affiliations should run across the full width of
the page in a single column 17.8 cm (7 in.) wide. The title should be in
18-point bold Helvetica. Authors' names should be in 12-point bold Times, and
affiliations in 12-point Times 12-point (not bold, nor italic).
You may place some address information in a footnote, or in a named section at
the end of your paper if it becomes inconvenient to fit them in the space
available. Please use full international addresses.

\subsubsection{\LaTeX\ Commands}
There are two ways to format the author and affiliation information  with the
\LaTeX\ document class. Using these methods ensures a consistent format for
this information across papers.

First, you can use the \texttt{\textbackslash author} and 
\texttt{\textbackslash affiliation} commands to automatically produce a block
like the one at the top of this document:
\begin{verbatim}
  \author[1]{Author One}
  \author[1,2]{Author Two}
  \affiliation[1]{Department ...}
  \affiliation[2]{...}
\end{verbatim}
The optional argument to each command is the superscript symbol to match each
author with their affiliation(s).

Second, for more complex formatting, use
\texttt{\textbackslash author} commands alone (without
\texttt{\textbackslash affiliation}):
\begin{verbatim}
  \author{
    \authorname{Author One}\\
    \authoraffil{Department of Examples\\
      Sample University\\
      City, Country\\
      \mailto{one@example.com}}}
  \author{...}
\end{verbatim}
Use \texttt{\textbackslash authorname} and \texttt{\textbackslash authoraffil}
to correctly format the author names and affiliation information, respectively.

When using the second method, you should also use
\texttt{\textbackslash author\-list} to set a comma-separated list of
the author names that will be written into the PDF metadata:
\begin{verbatim}
  \authorlist{Author One, Author Two, 
    Author Three}
\end{verbatim}

If the default spacing of the author information is not appropriate, it can be
adjusted with four lengths:
\begin{itemize}
  \item \texttt{\textbackslash authorwidth} controls the width of each author
    name.
    Adjust this if you find that there is too much space between author names,
    or long names are wrapped.
  \item \texttt{\textbackslash affilwidth} controls the width each affiliation.
  \item \texttt{\textbackslash authorsep} controls the horizontal space
    between author names.
  \item \texttt{\textbackslash affilsep} controls the horizontal space between
    affiliations.
\end{itemize}

Finally, if you need to insert some text below the author and affiliation
blocks (useful for long email addresses), use the
\texttt{\textbackslash authorpostscript} command. Refer to this document's
source for examples of these commands.

\subsection{Abstract and Keywords}
Every submission should begin with an abstract of about 150 words in the
\texttt{abstract} environment, followed by a set of keywords using
\texttt{\textbackslash 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 paper. It 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,
and should be separated by semi-colons. The second set (using
\texttt{\textbackslash classification\{...\}}) are used to catalogue the paper
in the ACM Digital Library. The latter are entries from the ACM Classification
System~\cite{acm_categories}. In general, it should only be necessary to pick
one or more of the H5 subcategories, see:
\url{http://www.acm.org/class/1998/ccs98.html}.

The \texttt{\textbackslash category} command formats the classifications 
correctly, and takes three or four arguments---one for each component from the
classification.

\subsection{Overful Lines}
\LaTeX\ will sometimes create overfull lines that protrude into margins; these
will be indicated in \texttt{preprint} mode with a solid black rectangle. To fix
these protrusions (like~the~one~on~this~line), you should first try the
\href{http://ctan.org/pkg/microtype}{\texttt{microtype}} package, which allows
small adjustments to the typesetting metrics (character protrusion and font
expansion). You may also want to encourage \LaTeX\ to hyphenate the offending
word (with \texttt{\textbackslash -}).\footnote{If the situation is dire, you 
can try \texttt{\textbackslash sloppy} in your document's preamble, which
essentially asks \LaTeX\ to prefer underfull lines with extra whitespace; for
more details, see
\url{http://www.economics.utoronto.ca/osborne/latex/PMAKEUP.HTM}.}

\subsection{First Page Copyright Notice}
Leave 3 cm (1.25 in.) of blank space for the copyright notice at the bottom of
the left column of the first page. This copyright notice will only appear in
\texttt{final} mode, and should be formatted using the following commands (as
appropriate for the publication venue):
\begin{verbatim}
  \confname{CHI'13}
  \confdate{April 27--May 2}
  \confyear{2013}
  \conflocation{Paris, France}
  \procissn{XXX-X-XXXX-XXXX-X/XX/XX}
  \doi{10.1000/182}
  \copylicense{...}
\end{verbatim}

The argument to \texttt{\textbackslash copylicense} should be one of:
\begin{enumerate}
  \item\texttt{\textbackslash acmcopyright}, 
  \item\texttt{\textbackslash authorlicense}, or 
  \item\texttt{\textbackslash openlicense}; 
\end{enumerate}
depending on the licensing option you have selected.

\subsection{Subsequent Pages}
On pages beyond the first, start at the top of the page and continue in
double-column format.

The two columns on the last page should be of equal length. This can be 
accomplished either using a package like 
\texttt{\href{http://ctan.org/pkg/balance}{balance}}, or by manually placing
a \texttt{\textbackslash vfill\textbackslash eject} at the correct point in
the source or \texttt{bbl} file.

\subsection{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
\cite{Card1983,Card1990,Card1991,Gillick1996}.
The bibliography section should be formatted with text aligned ``ragged right'',
and not justified (this will be setup for you if you are using
\texttt{\href{http://ctan.org/pkg/natbib}{natbib}}).

For papers from conference proceedings, include the title of the paper and an
abbreviated name of the conference (e.g., for CHI 2003 proceedings, use
\textit{Proc. CHI '03}). Do not include the location of the conference or the
exact date; do include the page numbers if available. See the example
citations at the end of this document.

Your references should be published materials accessible to the public. Internal
technical reports may be cited only if they are easily accessible (i.e., you
provide the address for obtaining the report within your reference) and may be
obtained by any reader for a nominal fee. Proprietary information may not be
cited. Private communications should be acknowledged in the main text, not
referenced (e.g., ``[Robertson, personal communication]'').

\section{Sections}
The heading of a section should be in Helvetica 9-point bold, and will be
formatted in all capitals by \texttt{\textbackslash section}. Sections should
not be numbered.

\subsection{Subsections}
Headings of subsections should be in Helvetica 9-point bold in ``title case''.
For instance, a word like \emph{the} or \emph{of} is not capitalised unless it
is the first word of the heading.

\subsubsection{Sub-subsections}
Headings for sub-subsections should be in Helvetica 9-point italic with only the
initial letters capitalised.
Standard \texttt{\textbackslash sec\-tion}, \texttt{\textbackslash
subsection}, and \texttt{\textbackslash subsubsection} commands will work as
expected.

\paragraph{Paragraph} Labels for individual paragaphs can also be used with
\texttt{\textbackslash paragraph}. A trailing period will automatically be
appended by the command.

  \centering
  \includegraphics[width=0.9\columnwidth]{figure}
  \caption{Images should have a high resolution---preferably a vector image 
      for line-art or charts.}
  \label{fig:sample}
\end{figure}

\section{Figures and Tables}
Place figures and tables at the top or bottom of the appropriate column or
columns (try not to place them in the middle of a column), on the same page as
the relevant text (see Figure~\ref{fig:sample}). A figure or table may extend
across both columns to a maximum width of 17.78 cm (7 in.).

Captions should be Times 9-point bold. They should be numbered (e.g.,
``Table~\ref{tab:table1}'' or ``Figure~\ref{fig:sample}''), centred, and placed
beneath the figure or table. Please note that the words ``Figure'' and ``Table''
should be spelled out (e.g., ``Figure'' rather than ``Fig.'') wherever they
occur.

Tables should be formatted cleanly, with good contrast and spacing. The
\href{http://ctan.org/pkg/booktabs}{\texttt{booktabs}} package provides commands
for proper vertical spacing and horizontal rules. The
\textit{Publication Manual of the APA}~\cite{apa} has additional guidance on how
to design tables for maximum clarity. In general, limit the use of rules (lines)
to those that are necessary for clarity (and never use vertical rules), do not 
use background colours or shading, and ensure that the table can be understood
on its own.

\begin{table}
  \centering
  \begin{tabular}{ccc}
    \toprule
    & \multicolumn{2}{c}{Caption Location} \\
    \cmidrule(r){2-3}
    Object & Pre-2002 & 2003 onwards \\
    \midrule
    Tables & Above & Below \\
    Figures & Below & Below \\
    \bottomrule
  \end{tabular}
  \caption{Table captions should be placed below the table.}
  \label{tab:table1}
\end{table}

\section{Language, Style, and Content}
The written language of SIGCHI is English. Spelling and punctuation may use any
dialect of English (e.g., British, Canadian, US, etc.) provided this is done
consistently. Hyphenation is optional. To ensure suitability for an
international audience, please pay attention to the following:

\begin{itemize}
\item Write in a straightforward style.
\item Try to avoid long or complex sentence structures.
\item Briefly define or explain all technical terms that may be unfamiliar to
  readers. For example:
  \begin{itemize}
    \item Explain all acronyms the first time they are used in your text---e.g.,
      ``Digital Signal Processing (DSP)''.
    \item Explain local references (i.e., not everyone knows all city names in a
      particular country).
    \item Explain ``insider'' comments. Ensure that your entire 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).
    \item Explain colloquial language and puns. Understanding phrases like ``red
      herring'' may require a local knowledge of English. Humour and irony are
      difficult to translate.
  \end{itemize}
\item Use unambiguous forms for culturally localised concepts, such as times,
  dates, currencies and numbers (e.g., ``1-5-97'' or ``5/1/97'' may mean 5
  January or 1 May; ``seven o'clock'' may mean 7:00 am or 19:00). For
  currencies, indicate equivalences---e.g., ``Participants were paid 1,000
  rupees, or roughly USD\$15.''
\item Be careful with the use of gender-specific pronouns (he, she) and other
  gendered words (chairman, manpower, man-months). Use inclusive language that
  is gender-neutral (e.g., she or he, they, chair, staff, staff-hours,
  person-years). Refer to the APA's
  ``\href{http://supp.apa.org/style/pubman-ch03.00.pdf}{\it Guidelines for 
  Unbiased Language}''~\cite{apa} for advice and examples regarding  gender and
  other personal attributes.
\item If possible, use the full (extended) alphabetic character set for names of
  persons, institutions, and places (e.g., Gr{\o}nb{\ae}k, Lafreni\'ere,
  S\'anchez, Universit{\"a}t, Wei{\ss}enbach, Z{\"u}llighoven, \r{A}rhus, etc.).
  If using non-Latin characters, provide appropriate romanisation.
\end{itemize}

\section{Page Numbering, Headers, and Footers}
The \texttt{preprint} and \texttt{submission} versions of your document will
have page numbers centred in the footer. These will be removed in the
\texttt{final} version of accepted papers, as page numbers, headers, and footers
will be added by the conference printers.

\section{Producing and Testing PDF Files}
We recommend that you produce a PDF version of your submission well
before the final deadline. Your PDF file must be ACM DL Compliant. The
requirements for an ACM Compliant PDF are available at:
{\url{http://www.sheridanprinting.com/typedept/ACM-distilling-settings.htm}}.

Test your PDF file by viewing or printing it with the same software we will use
when we receive it, Adobe Acrobat~\cite{acrobat}.

% Use `balance' to ensure that the columns on the last page line up. 
% Getting this to work can be a bit tricky, because the \balance command 
% must appear in the first column of the last page.
%
% If balance doesn't work for you, you can remove it and hard-code a column 
% break in the bbl file:
%     http://stackoverflow.com/questions/2149854/
%
\balance

\section{Blind Review}
For archival submissions, CHI requires a ``blind review''. To prepare your
submission for blind review, switch the document mode to \texttt{submission} to
remove author and institutional identities in the title and header areas of the
paper. You may also need to remove part or all of the ``Acknowledgments'' text.
Further suppression of identity in the body of the paper and references is left
to the authors' discretion. For more details, see the submission guidelines and
checklist for your submission category.

\subsection{\LaTeX\ Commands}
The \texttt{\textbackslash preprintonly\{...\}},
\texttt{\textbackslash sub\-mis\-sion\-only\{...\}}, and
\texttt{\textbackslash finalonly\{...\}} commands can be used to wrap content
that should only appear in a particular mode when the document is compiled
(e.g., TODO notes).

A \texttt{\textbackslash hideforsubmission\{...\}} command will hide content
in \texttt{submission} mode only---for example, the ``Acknowledgements''
section, or URLs that may identify the authors.

\section{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 explain 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 they will find your work useful. 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.
