Nike’s newest bit of tech is a watch/band that tells you more than whether you’re late for that very important date. which isn’t nearly as important to the FuelBand® as how hard you’re trying to get to it, measured in steps and calories, and displayed as one or the other, or in Nike’s own units as “fuel,” which is computed from the unit’s three axis accelerometer.
How is it computed? Nike isn’t saying, exactly, except that they “worked with some of the world’s top experts in science and sports to engineer NikeFuel algorithms based on oxygen kinetics.” Actually, it appears that the Fuel score is a function of how much the device is moved, regardless of how hard you had to work to do it, which Nike refers to as a “normalized” score. So it seems they’re telling you the real score, not one graded for effort.
The fun doesn’t stop at your wrist, as there are a host of tools available for smartphone (so far that means iPhone) or PC to analyze your performance throughout the day, set goals for yourself (which show up on your wrist as a line of red dots you have to eat up to get to green ones), and share your accomplishments with an online community.
The FuelBand costs $149 and won’t be available till February 22nd, but you can order it now.
