Before development started we worked with MuJo Fitness to understand their requirements and developed comprehensive user and technical specification documents. We watched patients using the machines in situ, and used that information to generate a series of detailed user wireframes describing how people would interact with the machine and the app. We built a series of click-through prototypes which we used in further user testing. Testing extended into such things as ensuring font-sizes were suitable and that any colours used were appropriate.
We also worked with teams of Physiotherapists at the RNOH on the design of the back end. There were specific occupational factors which, we found, had a material impact on our initial designs - and by a process of iterative improvement we were able to factor them out.
Before deployment, we set up end-to-end system tests involving physiotherapists, doctors and patients
