The NIKE+ FuelBand is worn on the wrist and uses accelerometry to provide information about different activities through movement of the wrist via a LED dot matrix display. Four metrics are available: Time, Calories, Steps and NikeFuel. Unlike calorie counts, which vary based on someone’s gender and body type, NikeFuel is a normalized score that awards equal points for the same activity regardless of physical makeup.
Users set a daily goal of how active they want to be, and how much NikeFuel they want to achieve. The NIKE+ FuelBand displays a series of 20 LED lights that go from red-to-green as the user gets closer to their goal. The FuelBand syncs with the Nike+ website through a built-in USB, or wirelessly through Bluetooth to a free iPhone app, to record activity and track progress every day. The app interface also provides encouragement and motivation as goals are achieved.
