Nike Retail Fit Prototype App and Electronics Prototyping for a Nike App which measures your fit size across various Nike product lines from two photos from your mobile phone. PROTOTYPE TEAM: Mike Creighton, through Instrument with Axiom for Nike TAGS: installation,app,retail,sensors App Screens Most of the work on the app experience involved making the process as quick and easy as possible for users, getting them comfortable with the idea of having their picture taken and highlighting the benefits of having accurate sizing across multiple product lines. It was a fun UX challenge. Prototype 1 The implementation of the physical device came in phases. Above is the first rough prototype, just a car phone holder mounted to a desk, and a laser cut foam ring outfitted with LEDs to test a ring shape as a form factor. In user testing, we would physically trigger lighting effects with a button to correspond to various user interactions. Prototype 2 The next step was to develop a free standing and fully autonomous prototype. We dubbed it the Christmas Tree, because I used a tree stand to hold the pole upright. One requirement was that there be no communication between the stand and the user's mobile device - wifi, bluetooth, RFID, etc. So to synchronize the lighting effects with the app experience, we programmed the app so that, once upright and motionless, it triggered a camera flash which was detected by a photocell mounted in the phone holder. Prototype 3 For the final stages of user testing we needed a polished device, and turned to the experts at Axiom, who in less than two weeks had developed a custom molded stand to neatly house away all the wires and electronics and diffuse the LEDs. Later iterations incorporated battery power and indicators, and a 2 piece assembly so the stand could be broken down for transport for testing in various Nike stores.
