+\begin{itemize}
+    \item UCD doesn't mean talking \textit{to} the users and asking what they want {\scriptsize (that's pretty much a user study)}
+    \item UCD doesn't mean testing the usability of the design in the end
+    \item UCD is not just for user interfaces or software {\scriptsize (it can also be for Programming Languages)}
+    \item UCD doesn't guarantee a perfect design {\scriptsize (duh)}
+\end{itemize}
+
+So, what is it then? It is characterized by:
+\begin{enumerate}
+    \item \bi{An early focus on users and tasks} {\scriptsize (get a psychology degree first)}
+    \item \bi{Empirical measurement} {\scriptsize (Come up with some sort of measurement of performance)}
+    \item \bi{Iterative Design} {\scriptsize (Identify and fix problems)}
+\end{enumerate}
