MotionQ: Operator-Conditioned Motion Quotients for Cross-Observation WiFi Gesture Recognition
Xiang Zhang, Huan Yan, Geying Yang +4
WiFi gesture recognition is accurate in fixed deployments but often degrades when user orientation, available links, or transceiver placement changes. Unlike ordinary domain shifts…
AirKey: Multimodal Acoustic-Assisted WiFi Sensing for Zero-Training Robust PIN Inference
BaiChuan Wu, Bin Liu, Xiang Zhang +6
Contactless keystroke inference via WiFi sensing highlights severe privacy threats, yet its real-world feasibility is hindered by two fundamental physical and deployment bottleneck…
Breaking Coordinate Overfitting: Geometry-Aware WiFi Sensing for Cross-Layout 3D Pose Estimation
Songming Jia, Yan Lu, Bin Liu +7
WiFi-based 3D human pose estimation offers a low-cost and privacy-preserving alternative to vision-based systems for smart interaction. However, existing approaches rely on visual…
Beyond Physical Labels: Redefining Domains for Robust WiFi-based Gesture Recognition
Xiang Zhang, Huan Yan, Jinyang Huang +6
In this paper, we propose GesFi, a novel WiFi-based gesture recognition system that introduces WiFi latent domain mining to redefine domains directly from the data itself. GesFi fi…
CamLoPA: A Hidden Wireless Camera Localization Framework via Signal Propagation Path Analysis
Xiang Zhang, Jie Zhang, Zehua Ma +9
Hidden wireless cameras pose significant privacy threats, necessitating effective detection and localization methods. However, existing solutions often require spacious activity ar…
Dynamic Information Dissemination Model Incorporating Non-Adjacent Node Interaction
Xinyu Li, Jinyang Huang, Xiang Zhang +5
Describing the dynamics of information dissemination within social networks poses a formidable challenge. Despite multiple endeavors aimed at addressing this issue, only a limited…
Information Dissemination Model Based on User Attitude and Public Opinion Environment
Xinyu Li, Jinyang Huang, Xiang Zhang +5
Modeling the information dissemination process in social networks is a challenging problem. Despite numerous attempts to address this issue, existing studies often assume that user…
