I designed the user interface for controlling phone playback on a fitness watch.
Problem: Limited interface
The new feature had to match the existing app ecosystem in terms of design and interactions. I worked closely with firmware and mobile app engineers to comply with the technical constraints on both watch and phone side.
Solution: Test to confirm
Usability of the architecture and the interactions were tested before, during and after launch and the final feature received extremely positive feedback.www.engadget.com
