摘要
Apparatus and method for using map data of a known route to calibrate an accelerometer to one or more physiological parameters of a user. In one embodiment, the calibration comprises determining a current position of a user; consulting map data to identify a route having a starting and/or ending position within a predefined proximity to the current position, the route having a known length; collecting data with the accelerometer as the user traverses the route; calculating a calibration factor based on one or more physiological qualities specific to the user; and causing the calibration factor to be stored and applied to subsequently collected data from the accelerometer.
