Check out some great stories of how DFA teams and professionals go from low-fidelity concepts to medium-fidelity prototypes while getting feedback to help their teams even more.
Effective ways to do this:
After winning the Most Creative Entry of the 2009 DiabetesMine Design Challenge, the Jerry the Bear team set on to build a prototype for their first testing session. The team hacked a Furby for its eyes and hooked up Arduino boards and sewing up cloth and foam around it to make their first prototype. It’s not perfect but it’s a start to learning more about their user and test out some of the concepts - and that’s what the team wanted!

DFA UofI team focused on helping machine workers, especially forklift drivers, more aware of their surroundings for the safety of both the drivers and those around the lift. After coming with a concept that combined a mirror and a light system, the team went out to a hardware store to start building and get some inspiration.
