16 Claims

1. A method for identifying a status of a user, comprising:

emitting a radiofrequency (RF) signal from a RF transceiver, toward the user;

receiving a backscattered RF signal with the RF transceiver, the backscattered RF signal backscattered from the user, wherein the backscattered RF signal measures a vital sign of the user;

using an audio sensor to sense a sound produced by the user;

identifying a plurality of moving objects based upon the backscattered RF signal;

extracting separate object radar data from the backscattered RF signal for each identified moving object;

identifying one of the identified plurality of objects as the user,

identifying the status of the user based on both the separate object radar data of the one of the plurality of identified moving objects identified as the user and the sensed sound; and

providing a feedback to the user or a third party based on the identified status, wherein the feedback provides notification of the status to the third party or the feedback assists the user.
