Abstract: An electronic pedometer device can be calibrated using other pedometer devices that the user happens to be wearing. For example, a first pedometer can be incorporated into a device wearable on a first portion of a user's body (e.g., the wrist) while a second pedometer is incorporated into a device wearable on another portion of the user's body (e.g., the waist). The pedometer devices can communicate with each other to initiate a calibration period, during which data regarding measured accelerations, step count and/or user location is gathered. After the calibration period, one or both of the devices can use the data to compute calibration parameters, such as a conversion factor for converting a step count to distance and/or other parameters for converting measured accelerations to distance traveled.
