Designed to be worn throughout the day, NIKE+ FuelBand is an ergonomic wristband that 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 (a normalized score that awards equal points for the same activity regardless of physical makeup or gender).
Users set a daily goal of how active they want to be, and how much NikeFuel they want to achieve. The band displays a series of 20 LED lights that go from red-to-green as the user gets closer to their goal. FuelBand syncs with the Nike+ website through a built-in USB, or wirelessly through Bluetooth to an iPhone app which records activity, tracks progress every day and provides encouragement and motivation as goals are achieved.
It also works as a nice minimal watch..!
