\section{Literature Review}  A similar project we looked at was a Phidget controller for a flight simulator by a former Computer Science student at Swansea University. While his web page written on the subject focused more on the implementation of the game itself rather than the implementation of the Phidgets, we still took some inspiration from website, including his physical controller design and the use of RFID tags.  \cite{Yai:2012:Online} Some inspiration was also drawn from the Google Earth Leap Motion controls. \cite{Google:2013:Online}
