 \section{Conclusion}
 \label{sec:label}
+Since keyboards are still the main data input device while using a computer and
+are also found to be related to discomfort or even \glsfirst{WRUED}
+\cite{pascarelli_wrued}, we tried to evaluate a possible modification to the
+existing keyboard design, that does not require the consumers to extensively
+adapt their typing behaviour, nor the producers to massively deviate from
+existing manufacturing processes. Therefore, we created a keyboard that used
+keyswitches with actuation forces, related to the specific finger the keyswitch
+is operated with.
