Apple are really starting to get their act together as regards switch access so it seems looking at previews of the iOS7 accessibility options.
The "Activate a switch on your input device now, or enable a built-in switch" looks like a way to make all the disparate methods of interfacing work (I hope). Love the addition of the head-switch using the built in camera. I assume accuracy would improve with the iPhone, iPad, iPod being mounted, rather than wobbling around in the hands of the user.
