Abstract

An activity monitoring device accumulates a count of steps taken as an individual bearing the activity monitoring device travels by foot along a route, and wirelessly acquires positioning data from a discrete global-positioning device corresponding to a sequence of locations along the route. The activity monitoring device iteratively revises an estimated stride length of the individual based on the positioning data and the step count and iteratively updates a travel distance on a display of the activity monitoring device according to the step count and the estimated stride length as the individual proceeds from one location in the sequence to the next.
