Re: Possible guideline about non-keyboard input devices

this looks pretty good. I have a niggle that the items below are too
specific but can't tease it out at the moment. This would cover touch
interface, voice, mental (brain wave) etc.
 I was wondering if we wanted to say 'input device/method'. Device sounds
external, like a keyboard or a mouse. I know the capacitive screen on my
smart phone is the input device, but I just think of it as my phone (it
just happens to have a self contained non-replaceable touch screen). The
input method is inherent in the device. you can't separate them. However,
you can add an additional device (bluetooth or usb keyboard for example)
