US Navy will replace touchscreen with mechanical controls on its destroyers

It's an interesting thought. You'd want to use a full bandwidth data channel (e.g. Bluetooth) for anything complicated.

But for simple things, if possible without affecting the other parts of the screen, it'd be amazing to have a broadly supported, low bandwidth standard.

I can't really make sense of the bandwidth (information rate) of a tactile interface. A measure in units of length would make more sense to me.

Any digital control signal effectively has a minimum bandwidth.

This might be as simple as "Here's my encoded position * frequency of sampling", but for a general interface you'd want something adaptable.

What if there were two dials on the control? Two dials and three buttons? One dial, four buttons, and a joystick?

It's enough for knobs of 1 inch spacing or wider, no easy support for fancy geared knobs that coaxially have a rough setting and a fine adjustment.
