The modern car is really a four-wheel computational platform. Yet I'm rarely made aware of this when I drive it. Furthermore, when I go to the automotive showroom, I don't have to ask what operating system or presentation manger the car uses. Here, at least, computers have finally gotten out of the way. The field of human-computer interaction is really configured around this central paradox.
Designers struggle to produce simplicity out of complexity, direct connectivity out of mediation.
Instead of drawing attention to itself, the best design lets us reach through computers into the world, allowing us to focus on creating value, not manipulating tools. So, for example, in panic stops and radical curves, the computational power in my car doesn't add to my problems by drawing attention to itself. Instead, it invisibly helps connect me to the road and the world outside. As they adapt to current practice, new technologies become less visible. Yet, simultaneously, by adopting these new technologies, current practice continuously evolves.
