Hi, We have just published some new technical documentation about how the input system works. In particular, the documentation describes what Android expects from touch screen device drivers and what is different in Ice Cream Sandwich. There is also a large section about keyboards, key maps, and HID. More content about mice, joysticks, trackballs and other things will be on the way soon.
