The small screens are coming, and we’re going to have to adjust our design processes accordingly. Emily Schwartzman does a great job of exploring how they worked through some of this complexity in Cooper, Augmedix and Google Glass: No Real Estate? No Problem:

Designing for Google Glass made us rethink the way we do software design. Many of our projects devote a significant amount of time to defining the framework of an application and developing the detailed design of key screens. When designing for Glass, we discovered that these phases needed almost no time, given the restrictive framework and visual language defined by Google. For future projects we might devote more time to refining personas and scenarios. We might even name the project phases a little differently—instead of “detailed wireframes” it might be “detailed scenarios.”

In general, Glass design projects will be focused more on flows than screens, and spending time on scenarios will help crystallize the flows.
