[Tex/LaTex] Slide ticker in beamer presentations

Question

I am using 'beamer' for presentations.
I have a Main Titles and a few slides under each.

For example,

Introduction has 4 slides
Methods have 5 slides.

I want to put kind of a ticker at the top of each slide saying what slide we are at currently. For Introduction it should have 4 small circles (coz 4 slides) below it and the slide number should be a highlighted circle.

How can I go about it?
Thanks

You could choose a beamer theme which supports that. For example Singapore:

\documentclass{beamer}
\usetheme{Singapore}
\begin{document}
\section{Introduction}
\subsection{One}
\begin{frame} text \end{frame}
\subsection{Two}
\begin{frame} text \end{frame}
\subsection{Three}
\begin{frame} text \end{frame}
\subsection{Four}
\begin{frame} text \end{frame}
\section{Methods}
\subsection{One}
\begin{frame} text \end{frame}
\subsection{Two}
\begin{frame} text \end{frame}
\end{document}

Here's the top of a frame, where subsection three of the introduction is highlighted.

Or

\usetheme{Szeged}

Or

\usetheme{Darmstadt}

There are related themes such as Berlin, Ilmenau, Dresden and Frankfurt, with such a navigation.

Also the progressbar theme is interesting, if you wish to show the frame progress.
