Athletic performance monitoring with overstride detection
First Claim
Patent Images
1. A system comprising:
- an inertial sensor configured to measure an acceleration in a moving direction of a user foot of a user during locomotion and output an acceleration signal responsive to the acceleration;
a memory storing a stride acceleration motion profile; and
a processing system configured to process the acceleration signal and the stride acceleration motion profile to determine a user stride improvement.

Abstract
Methods and apparatuses for athletic performance monitoring are disclosed. In one example, a system includes an inertial sensor configured to measure an acceleration in a moving direction of a user foot of a user during locomotion and output an acceleration signal, a memory storing a stride acceleration motion profile, and a processing system configured to process the acceleration signal and the stride acceleration motion profile to identify a reduced user overstride.

7. A non-transitory computer readable storage memory storing instructions that when executed by a computer cause the computer to perform a method for analyzing athletic activity comprising:
-
receiving a first data associated with a first foot sensor output signal responsive to a motion of a first portion of a user foot; receiving a second data associated with a second foot sensor output signal responsive to a motion of a second portion of the user foot; and comparing the first data and the second data to identify a desirable stride characteristic or an undesirable stride characteristic. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. An athletic performance monitoring system comprising:
-
a first foot worn device configured to be worn on a first foot portion, comprising; a first sensor configured to output first sensor data associated with movement of the first foot portion; a second foot worn device configured to be worn on a second foot portion, comprising; a second sensor configured to output second sensor data associated with movement of the second foot portion; and an arm worn device configured to be worn device worn an arm of a person, comprising; a processing system comprising a processor configured to receive the first sensor data and the second sensor data and identify an undesirable user stride motion; and a user interface. - View Dependent Claims (16, 17, 18, 19, 20)
