A few months ago I entered a prototyping competition, The ProtoHype Challenge, with some coworkers. This competition is being sponsored by both TechShop and the University of Pittsburgh’s Clinical and Translational Science Institute. The goal of the competition was to pair people with good prototyping skills (TechShop Members) with ideas for a medical device or biomedical research tool. Ten groups from Pitt provided challenges from which the prototyping teams could submit proposals. Our team was lucky enough to be chosen to prototype our favorite challenge: calibration of commercial motion capture IMUs (Inertial Measurement Units).
