\section{Conclusion}  We have successfully created a working controller for Google Earth, with a layout fit for demonstration purposes. The interface is intuitive, intuitive and logical,  and can be learned easily. 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. They 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 controller is not a tangible interface, it fully meets the design aims and is fit for purpose.
