A student and I began discussing and simultaneously sketching flows and ideas. Using whiteboard-surfaced iPhone-canvases, we were able to ideate and sketch rapidly at low cost, while maintaining the constraints of mobile UI design.
Using the physical canvases, we were able to work open and quickly iterate on different use cases related to our system design and user flows.
Lo-Fi prototyping and evaluation
Using a simple prototyping app, we created Lo-Fi prototypes around different use-cases and evaluated these with relevant users.
With insights from the evaluations, we designed UI wireframes with Sketch and used these as a final way of defining the system and it’s use-cases before designing a Hi-Fi prototype
