\section{Discussion}

\subsection{Pros \& Cons}

\begin{frame}{Interaction design}
	\begin{columns}[c]
		\begin{column}{0.5\textwidth}
			\textbf{Pros}
			\begin{itemize}
				\item High responsiveness
				\item High accuracy (due to hand/finger control)
			\end{itemize}
		\end{column}
		\begin{column}{0.5\textwidth}
			\textbf{Cons}
			\begin{itemize}
				\item No feedback but sound itself
				\item dependent on muscle-memory
				\item dependent on eye-hand coordination
			\end{itemize}
		\end{column}
	\end{columns}
\end{frame}

\begin{frame}{Hardware design}
	\begin{columns}[c]
		\begin{column}{0.5\textwidth}
			\textbf{Pros}
			\begin{itemize}
				\item Free-Libre-Open
				\item Lightweight
				\item Modular
				\item Simple to build
				\item Mainly consisting of electronics and case
				\item Single patch cable (passive PoE)
				\item No Knobs, sliders, etc. that can break
				\item Works in any environment (excluding vicinity to MRI, LHC)
			\end{itemize}
		\end{column}
		\begin{column}{0.5\textwidth}
			\textbf{Cons}
			\begin{itemize}
				\item Intermediate SMD soldering skills
				\item A lot of manual wiring
				\item Somewhat tedious calibration
				\item Case needs laser cutter
			\end{itemize}
		\end{column}
	\end{columns}
\end{frame}

\begin{frame}{Firmware design}
	\begin{columns}[c]
		\begin{column}{0.5\textwidth}
			\textbf{Pros}
			\begin{itemize}
				\item Free-Libre-Open
				\item Modular output engines
			\end{itemize}
		\end{column}
		\begin{column}{0.5\textwidth}
			\textbf{Cons}
			\begin{itemize}
				\item Too many configuration parameters
			\end{itemize}
		\end{column}
	\end{columns}
\end{frame}

\begin{frame}{Communication}
	\begin{columns}[c]
		\begin{column}{0.5\textwidth}
			\textbf{Pros}
			\begin{itemize}

			\end{itemize}
		\end{column}
		\begin{column}{0.5\textwidth}
			\textbf{Cons}
			\begin{itemize}
				\item network-based
				\item OSC is not plug'n'play
				\item TUIO is not readily available
			\end{itemize}
		\end{column}
	\end{columns}
\end{frame}

\begin{frame}{Mapping}
	\begin{columns}[c]
		\begin{column}{0.5\textwidth}
			\textbf{Pros}
			\begin{itemize}
				\item endless combinations
			\end{itemize}
		\end{column}
		\begin{column}{0.5\textwidth}
			\textbf{Cons}
			\begin{itemize}
				\item needs a smart/configurable enough host application
			\end{itemize}
		\end{column}
	\end{columns}
\end{frame}

\subsection{Next steps}

\begin{frame}{Hardware design}
	\begin{itemize}
		\item Make calibration more automatic
		\item Reduce manual cabling
		\item Add 2 more rows of sensors for 3D?
		\item Make case flatter, sturdier?
		\item Magnetic force-feedback?
	\end{itemize}
\end{frame}

\begin{frame}{Firmware design}
	\begin{itemize}
		\item Implement configurable mapping engine?
	\end{itemize}
\end{frame}

\begin{frame}{Communication}
	\begin{itemize}
		\item Migrate to USB(-MIDI)?
	\end{itemize}
