Data-fusing activity monitoring device
First Claim
1. A method of operation within an activity monitoring device as an individual bearing the activity monitoring device proceeds by foot along a route, the method comprising:
- accumulating a count of steps taken by the individual based on signals from one or more sensors of the activity monitoring device;
wirelessly acquiring positioning data from a discrete global-positioning device corresponding to a sequence of locations along the route;
iteratively revising an estimated stride length of the individual based on the positioning data and the step count;
rendering an interface on a display comprising;
an indication of a real-time position of the individual based at least in part on the positioning data acquired from the discrete global-positioning device; and
a travel distance based on the estimated stride length and the total count of steps; and
iteratively updating the travel distance in real-time on the 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.

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.

11. An activity monitoring device comprising:
-
a display; wireless circuitry; one or more sensors to generate signals indicative of motion of an individual bearing the activity monitoring device; and processing circuitry coupled to the display, wireless circuitry and one or more sensors to; accumulate, based on the signals generated by the one or more sensors, a count of steps taken by the individual as the individual proceeds by foot along a route;
acquire, via the wireless circuitry, positioning data from a discrete global-positioning device corresponding to a sequence of locations along the route;iteratively revise an estimated stride length of the individual based on the positioning data and the step count; and iteratively update a travel distance on the display according to the step count and the estimated stride length as the individual proceeds from one location in the sequence to the next; wherein the display comprises; an indication of a real-time position of the individual based at least in part on the positioning data acquired from the discrete global-positioning device; and a travel distance based on the estimated stride length and the total count of steps. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
