"...a good interface should not call attention by itself, but should let us direct to the task. Interfaces can be immediately transparent"..."Instead of trying to create a magically intuitive interface by an unspecified process, designers should conciously exploit the user´s preexisting knowledge by looking for familiar interaction patterns that will be easy to learn and will quickly become transparent".

(Inventing the Medium. Murray Janet, 2012)

Is it all about leaving the designer´s whim to the side and get transparent/ camouflaged designs and get the task done? Maybe the next step is by using just what the interactor has in his own enviroment avoid instruments or machines, to be able to create a totally debugged and pure experience. It remembers me the hologram keyboard which I really would like to play with.
