\section{Conclusion}  We have successfully created a working controller for Google Earth, with a layout fit for demonstration purposes. The interface is intuitive and logical, and can be learned easily by users of any ability. For a user familiar with Google Earth, the controller should take a matter of seconds to pick up. The I/O devices each achieve a specific task that is physically similar to its actual control within the software. All components work together robustly, and can handle being activated concurrently without causing a problem. While the The  controlleris not a tangible interface, it  fully meets the design aims and is fit for purpose. purpose, and while the controller is not a tangible interface it can be readily upgraded by embedding the RFID tags in representational objects.
