Building better experiences—from forms that work for both humans and machines to designs that adapt to real-world conditions.

Environmental Design with the Device API


Real-world factors like low batteries and weak signal strength can turn even the most expertly crafted digital experience into a frustrating clustercuss. These factors are beyond your control, and, until recently, there was nothing you could do about them. Now there just may be. Tim Wright explains how to begin improving your users’ experiences under constantly shifting (and sometimes quite dreadful) conditions, via environmental design thinking and the Device API.

Jon Postel’s Robustness Principle, although usually applied to low-level protocols like TCP, offers a clue to designing experiences that meet human and machine needs with equal grace. Lyle Mullican explains.
