Title:
PHYSICAL STATE DETECTION METHOD AND SYSTEM BASED ON GAIT RECOGNITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/228418
Kind Code:
A1
Abstract:
A physical state detection method and system (400) based on a gait recognition device. The gait recognition device (410) is built in a cavity of an insole or a sole, and comprises a pressure sensor used to detect the pressure in the cavity. The detection method comprises: periodically sampling pressure measurement data output by the pressure sensor (S110); determining the change law of the pressure in the cavity according to the collected pressure measurement data (S120); recognizing gait information of a pedestrian according to the collected pressure measurement data and the change law of the pressure (S130), the gait information comprising the state of the foot falling to the ground, the stride frequency, the consistency of the paces, and the walking mode; and analyzing the state of the foot falling to the ground, the stride frequency, the consistency of paces, and the walking mode according to the preset detection rules to detect the gait-related physical state information (S140). The method can detect the pedestrian's physical state at any time and conveniently by means of the gait information, and facilitate users to conveniently grip the pedestrian's physical state, thereby improving the user experience.
