1. A machine-accessible medium including data that, when accessed by a machine, cause the machine to perform a method comprising:
- monitoring accelerations from an inertial sensor disposed in a chest strap, the inertial sensor having a plurality of axes;
processing the accelerations to determine one or more user activity statistics, the processing comprising;
creating a rolling average of accelerations for each of the plurality of axes;
comparing a value of the rolling average of accelerations for a first axis to values of the rolling averages of accelerations for one or more additional axes of the plurality of axes; and
assigning a dominant axis based upon relative values of the rolling averages of accelerations;
formatting the user activity statistics to a generic format understandable by a plurality of devices; and
transmitting the generically formatted user activity statistics from the chest strap to an electronic device.

Abstract
A method for monitoring human activity using an inertial sensor includes monitoring accelerations from an inertial sensor disposed in a chest strap. The accelerations are processed to determine one or more acceleration statistics. The acceleration statistics are formatted to a generic format understandable by a plurality of devices. The formatted acceleration statistics are then transmitted.
