Interaction method based on Wi-Fi fingerprint positioning and activity gesture joint recognition

The invention discloses a Wi-Fi fingerprint-based positioning and activity gesture joint recognition interaction method. The method comprises the following steps of collecting CSI data of a position of a Wi-Fi fingerprint and CSI data of an activity gesture through Wi-Fi equipment; extracting an amplitude value of the CSI data of the position of the Wi-Fi fingerprint and an amplitude value of theCSI data of the activity gesture, and forming a one-dimensional sampling matrix of the CSI data according to the synchronization time; preprocessing the one-dimensional sampling matrix of the CSI datato remove environmental noise and a high-frequency part in the one-dimensional sampling matrix; segmenting and up-sampling the preprocessed CSI data to obtain a CSI matrix corresponding to the position of the Wi-Fi fingerprint and a CSI matrix corresponding to the activity gesture; setting a one-dimensional convolutional neural network model; and performing feature extraction on the CSI matrix corresponding to the positio
