Good bye iPad, you were just too impractical. What we will keep is the accelerometer idea which is essentially the core idea we wanted. It is entirely possible to make an arduino accelerometer that is small and can be held with even two fingers. Hopefully this will be a method of control movement. We will still retain the idea of remapping movement to various button controls. We were also thinking of using the eyewriter for movement/directional control which uses the light reflected off your eyes. Heres the prototype:
For button controls (A,B,X,Y,L,R) we considered two options, the sip’N’puff’N’bite or the unique Tounge Drive. The Tongue Drive is essentially a set of retainers with sensors for certain buttons.
