One of the best ways to motivate people to change behavior is setting goals that can be attained and rewarding them for doing more. Nike has taken a unique tack in the activity tracking space with the introduction of the Nike+ FuelBand, which measures all of your activity all day long in a new unit called Fuel. Worn on the wrist, it captures motion and tells you how much Fuel you’ve earned, steps you’ve taken and calories burned. It syncs wirelessly to iPhones to give you a more detailed look over time and lets you adjust your goals and see your accomplishments. The elegant simplicity of the single button and deeper experiences on the mobile and web applications make it a truly addictive experience that has the power to encourage people to get off the couch and get moving.
