As a programmer with UI experience (for both physical and graphical UIs) I am aware that nothing stops us from deploying similar paradigms in the digital domain and this is yet another example to make the point, that it is possible.
Sadly few companies nowadays have any incentive to make their interfaces so neutral, egalitarian and simple. It seems to take a special kind of radicalism to commit to limited controls and not slap open ended navigational structures, menus and so on onto a touchscreen. Car interfaces come to my mind.
