A dataset for Wi-Fi-based human-to-human interaction recognition

This dataset contains Wi-Fi signals that were recorded from 40 different pairs of subjects while performing twelve different human-to-human interactions in an indoor environment. Each pair of subjects performed ten trials of each of the twelve interactions and the total number of trials recorded in our dataset for all the 40 pairs of subjects is 4800 trials (i.e., 40 pairs of subjects × 12 interactions × 10 trials). The publicly available CSI tool is used to record the Wi-Fi signals transmitted from a commercial off-the-shelf access point, namely the Sagemcom 2704 access point, to a desktop computer that is equipped with an Intel 5300 network interface card. The recorded Wi-Fi signals consist of the Received Signal Strength Indicator (RSSI) values and the Channel State Information (CSI) values.

本数据集收录了室内环境下，40组受试者两两配对开展12种不同人际互动行为时采集的Wi-Fi信号。每组受试者配对需针对12种互动各完成10次实验试次，本数据集总计收录4800组有效实验数据（即40组受试者配对 × 12种互动 × 10次实验试次）。本研究采用公开可用的信道状态信息（Channel State Information, CSI）采集工具，对商用现货接入点Sagemcom 2704发射的Wi-Fi信号进行采集，信号传输至搭载Intel 5300网络接口卡的台式计算机。所采集的Wi-Fi信号包含接收信号强度指示（Received Signal Strength Indicator, RSSI）值与信道状态信息（CSI）值。
