> "As many tactile buttons as you can reach without significantly moving your hands. And a keyboard already gets pretty close to that ideal..." The DataHand came even closer: https://en.wikipedia.org/wiki/DataHand https://en.wikipedia.org/wiki/DataHand but I'm not sre that's good; moving your hands to reach more keys, without looking, brings even more keys into reach. I can hit the control keys with the palms of my hands - and often do that with the palm of the knuckle under the pinky finger - and feel where they are by the gaps around them, similar with ESC and some of the F-keys, and backspace from its shape, etc. I don't know of a keyboard which is designed to maximise that effect, or how one would be.
