“It’s helpful to contrast designing for mobility with designing for sedentariness. What we hadn’t realized until we were designing explicitly for mobility is that, in the past, we had been designing not just for the “PC,” but for a sedentary experience. We shared unstated assumptions that people would remain in one place for long periods of time, with little change in their environment. We could take advantage of this with software experiences that rewarded deeper engagement, encouraged exploration and play, allowed for more complicated interactions to achieve a goal.”
