As the Android Wear and Apple Watch OS was in its infancy it required a great deal of research to ensure that the concepts could be realised. I spent a morning reading reviews, watching videos, playing with, screenshotting and printing various Apple Watch and Android Wear interfaces and patterns.
Once I started to delve deeper it became clear that the two tech giants had gone with very different approaches to wearable tech userflows. Google had very much gone down the route of “Google Now” and offered the user applications and “moments” that the wearer might find useful at that time and place (very contextual). Whereas Apple had very much stuck with what they know, offering the user a bunch of applications to choose from a cluster homescreen.
As with most app work I like to try and move into prototyping phase as soon as I can, this gets you away from looking at screens like static pictures and makes you consider function and flow.
I sketched small watch UI screens based on my research to get the flow right, iterating over and over for both Android Wear and Apple Watch. When I had flows mapped out I printed them to iterate further and ensure we were optimising for the small amount of screen space.
