1. A non-transitory computer-readable medium comprising computer-executable instructions that when executed by a processor is configured to perform at least:

  • receive acceleration data representing movement of an appendage of a user at a sampling rate processor located on a device configured to be worn on an appendage of a human, wherein the acceleration data was obtained by an accelerometer located on the device while the accelerometer is operating at a first sampling rate;

    based, at least in part, on the received acceleration data itself, classify the acceleration data into one of a plurality of activity categories representing sporting activity, recognized from a plurality of sporting activities, being performed by the user; and

    based upon at least the sporting activity, selecting a second sampling rate of hardware of the accelerometer, from a plurality of sampling rates for operating the accelerometer during the activity being performed by the user,wherein the selection of the first sampling rate and the second sampling rate are selected to prolong a battery life of the device,wherein the accelerometer is a first accelerometer and the medium further comprises computer executable instructions that when executed further perform at least;

    compare a value of acceleration data obtained from the accelerometer during its operation at the first sampling rate to a plurality of threshold values;

    determining that the value of acceleration data corresponds to a first threshold value within the plurality the threshold values; and

    based upon the correspondence to the first threshold value and a classified activity category, selecting a second threshold value.
