The genius of Nike's new product launch is not just the ability to track data in real-time and convert this into a common, universal currency known as Fuel -- one number, one button, via a simple, intuitive interface. The real genius is in combining all this fitness-tracking data with a fun game layer to motivate people to achieve their goals. The motivational element is activated via a mobile app that enables you to share achievements and accomplishments with friends.
Thanks to a built-in accelerometer, every action you take - from climbing the stairs to running around a track - can be converted into a single number. Fuel becomes a currency for comparing your activity with others, whether they are playing tennis, running, hiking or (as the Nike promo video would have us know) dancing like MC Hammer.
