Abstract

A method for detecting steps taken by a person in locomotion on foot having a step-detection apparatus carried on the person. The step-detection apparatus generates a signal in response to locomotion of the person. The signal is compared to the timing characteristics of human gait to identify steps taken. The step-detection apparatus can be carried in a front pants pocket of the person.

Claims

1. A method for detecting steps taken by a person in locomotion on foot, comprising the steps of:

(a) carrying a step-detection apparatus on said person,

(a1) said step-detection apparatus includes a step sensor and electronic controller,

(b) said step sensor generating a signal in response to locomotion of said person,

(c) said electronic controller measuring the time duration of, and the time duration between, features in said signal,

(c1) said electronic controller includes values of time durations of features, and time durations between features, that have been empirically determined to indicate a step has been taken in said signal from said step sensor,

(d) said electronic controller comparing said measured time durations to said empirically-determined values of time durations to identify step indications in said signal.

2. A step-detection apparatus using the step-detection method of claim 1, comprising:

(a) said step detection apparatus is contained in a pocket-sized enclosure carried in an ordinary front, lower-torso clothing pocket of a user,

(b) said enclosure is free to move within said pocket.
