+\subsection{Online and offline recognition}

+\begin{frame}{What is my Bachelor's thesis about?}
+    \begin{itemize}
+        \item Recognition of handwritten mathematical symbols
+        \item On-line recognition, not OCR!
+        \item Given a series of points $(x(t), y(t), b(t))$\\
+              I want to get the proper \LaTeX{} command.
+    \end{itemize}
+\end{frame}
+
+\begin{frame}{Why did I work on this topic?}
+    \begin{itemize}
+        \item \LaTeX{} is easy as soon as you know the \textbackslash{}commands.
+        \item It's hard to find the \LaTeX{} command of single symbols.
+        \item It's much harder to find complete formulas.
+    \end{itemize}
+
+    % I want to
+    % \begin{itemize}
+    %     \item provide a tool that enables beginners to get the best \LaTeX{} command
+    %           for their formula,
+    %     \item find out what works best for symbol recognition
+    %     \item and provide data and a platform to test new ideas for classifiers
+    % \end{itemize}
+
+    For now: recognition of isolated symbols. That means:
+
+    single symbol \enquote{formulas} rather than multi-symbol formulas

+About

+This is a 20 minutes presentation for my bachelors thesis. At this point,
