I've been hoping somebody would do that.

I have a only half-joking business idea to build high-quality physical controls for all of the crap touchscreen shit being forced upon us. High-end ovens for example rarely now include physical controls so (I'm looking at you Miele) so I would like an aftermarket thing that sticks on to the outside of it. Maybe even directly over the touch screen. Actually, hmm, that's a good idea. Maybe we need a device that is the size of various standard touch screens that can read the contents of the screen, interpret them, and then have some sort of way to do capacitance touch on the screen. All of this of course hidden from the user who just wants a damned analog knob.
