\setbeamercovered{dynamic}
  \begin{itemize}
\pause
  \item Social dynamics/human interaction 
    within
 different  environments ({\textcolor{red}{real time}} data collection).
 \pause
% \item {\textcolor{red}{Real time}} data
%   collection and visualization of the {\textcolor{red}{ evolving}}
%   network.
 \item Dynamics of both processes {\textcolor{red}{on}} the network and
   {\textcolor{red}{of}} the network $\mapsto$ computational
   epidemiology and computer science applications.
 \pause
\item Technology and data from
  {\textcolor{red}{Sociopatterns Project}}
  (\url{http://www.sociopatterns.org/}).
\bi \pause
\item  Science Gallery at
  the Trinity College, 
  Dublin, Ireland ($\sim 3$ months, $\sim 10000$ visitors).
\pause \item HT2009 conference, Turin, Italy ($3$ days, $\sim 100$ participants). 
\pause  \item More experiments just completed (school in Lyon, Bambin Gesù
   pediatric hospital in Rome).
 \ei

  \end{itemize}

\begin{frame}[t]{Overview of the Infrastructure }
\vspace*{-.5cm}
\bi
\item Tags exchange packets at various powers  and
report their contacts to antennas broadcasting the data to a server.
\item Low-power packets expose
  {\textcolor{red}{face-to-face}} interactions at small distances
  ($\sim 1$m).

  network in addition to

\item scalability  \pause
\item unobtrusiveness  \pause
\item low cost  \pause
\item open (hardware and software)  \pause
\item high spatial resolution $\sim 1$ meter  \pause

\begin{frame}[t]{Conclusions}
\setbeamercovered{dynamic}
\bi \pause
\item {\textcolor{red}{It works!}}
  Common sense results, but  through testing of the
  experimental infrastructure and the post-processing tools. \pause
\item Infrastructure  deployed in  much less predictable environments (school,
  hospital) $\mapsto$ work in progress. \pause
\item Network aggregation over different time periods (seasonality,
  trends, etc..). \pause
\item Network {\textcolor{red}{static}} properties ($P(k)$, $P(s)$, $P(w)$,
  diameter, assortativity,  etc..). \pause
\item Network {\textcolor{red}{dynamic}} properties: spread of epidemics and
  diffusion processes on a longitudinal network.
