AI总结:

针对现有WiFi人体感知多聚焦单用户、缺乏多用户基准数据集的问题,该研究提出首个WiFi多用户感知基准数据集WiMANS,含9.4小时以上双频CSI及同步视频,并用于基准测试主流模型,可推动相关领域研究。

摘要:

基于WiFi的人体感知以非侵入、无设备的方式分析用户行为,已展现出显著潜力,可应用于智能家居、医疗健康等多元场景。但以往多数研究聚焦单用户感知,在多用户场景下实用性有限。尽管近期研究已开始探索基于WiFi的多用户感知,但仍缺乏基准数据集支撑可复现、可对比的研究。为填补这一空白,我们提出WiMANS,据我们所知,这是首个基于WiFi的多用户感知数据集。WiMANS包含超9.4小时的双频WiFi信道状态信息(CSI)及同步视频,记录多用户的同时活动。我们利用WiMANS对当前最优的基于WiFi的人体感知模型和基于视频的模型进行性能基准测试,为未来研究提出新挑战与机遇。我们相信WiMANS能够拓展现有研究边界,推动基于WiFi的多用户感知研究发展。

英文摘要:

WiFi-based human sensing has exhibited remarkable potential to analyze user behaviors in a non-intrusive and device-free manner, benefiting applications as diverse as smart homes and healthcare. However, most previous works focus on single-user sensing, which has limited practicability in scenarios involving multiple users. Although recent studies have begun to investigate WiFi-based multi-user sensing, there remains a lack of benchmark datasets to facilitate reproducible and comparable research. To bridge this gap, we present WiMANS, to our knowledge, the first dataset for multi-user sensing based on WiFi. WiMANS contains over 9.4 hours of dual-band WiFi Channel State Information (CSI), as well as synchronized videos, monitoring simultaneous activities of multiple users. We exploit WiMANS to benchmark the performance of state-of-the-art WiFi-based human sensing models and video-based models, posing new challenges and opportunities for future work. We believe WiMANS can push the boundaries of current studies and catalyze the research on WiFi-based multi-user sensing.
