Prototype Building
I took my 3 scenarios & assembled storyboards in Sketch. I then did a .png export of all screens into a folder. These images were then simply dragged into Keynote. I drew on hotspots where I needed them & this has seemed to work quite well. It’s very basic but enough to get a prototype idea across – it would have been nice to have created some more complexity here – at present, the user needs to follow the task scenarios with the prototype (that is, follow the steps in the scenario) as building all possible clicks and interactions would have been extremely time-consuming and a lot of screens. This exercise did highlight problems that were not apparent on the paper prototypes however – size of buttons, aesthetics and where menu items were located for example.
