US 2019/0171279 A1 · METHOD AND SYSTEM OF OBTAINING AND TRACKING HUMAN POSTURE

Abstract

The present invention discloses a method and a system of obtaining and tracking the posture of a subject. Electromagnetic field transceivers may be placed at various locations on the subject, and may be coupled to a processor device, which may be disposed on the back of the subject. The processor device may send waveforms to selected electromagnetic field transceivers located at positions to be tracked. The selected electromagnetic field transceivers may transmit signals corresponding to these waveforms to additional electromagnetic field transceivers located near an origin point. Signals received by these additional electromagnetic field transceivers may be sent to the processor device, which may, based on voltage amplitudes/magnitudes of the received signals, determine the positions and motion trajectories for the electromagnetic field transceivers, which may correspond to positions and motion trajectories of different parts of the subject's body.

Dependent claims

A method of obtaining a human posture, comprising:

receiving, by a first electromagnetic field transceiver disposed on a limb of subject from a processor device, a waveform generated by a transmit waveform generating circuit of the processor device;
transmitting, via an antenna of the first electromagnetic field transceiver, a signal corresponding to the waveform;
receiving, via an antenna of a second electromagnetic field transceiver, the signal;
sending, by the second electromagnetic field transceiver, the received signal to the processor device;
determining, with the processor device, the voltage of the received signal;
and
determining, with the processor device, a coordinate corresponding to a position of the first electromagnetic field transceiver relative to a position of the second electromagnetic field transceiver based at least on the determined voltage.
