The dynamic between hard and soft car interactions is constantly evolving. From using dials and buttons to control what's on the screen, to thoughtfully-engineering steering wheel controls and to using a full-fledged touch screen—what is the intuitive baseline?
From car to car, the controls keep changing in their sensibility. One can expect a greater surface area of the new
digital cockpit to be covered in displays and a high degree of smart touch integrated into them. While the physicality of interactions becomes more intangible, it must remain rooted in physical memory.
It must also identify degrees of transformation with every interaction point. When a user wanted to change the volume in his car, he unthinkingly reached out for a constant dial/button that he was assured would always be in the same place and would never move. If that same volume control moves to a touchscreen dashboard and disappears once he's up changing the volume, he's going to have to use a greater portion of his cognitive ability each time he wants to change the volume. While designing every interaction, the user's underlying expectations of constancy need to be identified, mapped and maintained even if outward forms of interaction may change.
