This video by conquerearth shows a method for controlling Super Mario Bros. (in an emulator) with a theremin. This is quite an interesting idea and seems to work well.
The sound from the theremin is split into its frequency and amplitude components in real time, which are then mapped to values in a linear scale representing the X and Y axis. Pitch becomes horizontal control, and Volume becomes vertical control.
The X and Y scales are then cut up into different zones. In this case, Left; Right and dead zones for the horizontal, and a single trigger and dead zone for the vertical.
The trigger zones are then mapped onto a virtual joystick hooked into an emulator.
The end result is a fairly usable input control for playing games like mario. The bars give the much needed visual feedback as to how “in tune” you are, so you have a better feel of where the trigger points are.
