Filed: 2019-12-17
Abstract: Disclosed is a method of recognizing daily activities of a person indoors using channel status information (CSI) between a Wi-Fi transmitter and a Wi-Fi receiver. CSI signals transmitted between the Wi-Fi transmitter and the Wi-Fi receiver, which are respectively installed at certain positions in an indoor space, are collected, and high-frequency noise is removed, and only waveforms on activities of the person are extracted. From the extracted CSI signal waveforms, subsidiary return wave signals reflecting motions of the body of the person indoors are selected and normalized. From the normalized CSI signal waveforms, waveforms of a certain comparison section are extracted. The current activities status of the person in the indoor space is identified based on the similarities between the extracted waveforms and the reference waveforms of each activity of the person indoors, which are previously known. In the step of comparing activity patterns, the reference waveforms are reflected in a learning model secured and built through machine learning, so the extracted waveforms of the certain comparison section are provided as an input into the learning model. The learning model can be built by using a support vector machine (SVM) algorithm. The patterns of waveforms caused by daily activities of the person indoors, which are extracted from the Wi-Fi CSI signals of each time zone, are compared with the patterns of the reference waveform of each of daily activities, and the daily activities of the person indoors can be recognized.
