Lecture Content

The use of ubiquitous WiFi wireless signals for non-intrusive, contactless human behavior perception is an emerging and active research direction in recent years. At present, most WiFi non-contact human behavior sensing systems, whether for general behavior such as human daily activities or for fine behaviors such as gestures and lip recognition, are based on wireless signal mode and machine learning. However, these efforts are based on a common assumption that the pattern of signal changes produced by the same individual's activities is consistent. By introducing the Fresnel Zone Model originally used in the field of optics and communication to the field of indoor wireless non-contact sensing, we not only reveal the mechanism of wireless signals in the space to sense the movement of human bodies and objects, but also the position and orientation of the measured human body activity.

Speaker Introduction

Prof. Zhang Daqing is teaching at Peking University. He is a IEEE Fellow (Fellow), and Deputy Director of the Universal Computing Committee of the Chinese Computer Society. In 1996, he received his PhD from the University of Rome, Italy. He has served as a first-class tenured professor at the National Telecommunications Institute of Paris, France, and the director of the Smart Home Laboratory of the Singapore Institute of Information and Communications, and the founding director of the Situational Awareness Systems Department. His main research interests include pervasive computing, situational sensing computing, urban computing, and the Internet of Things. He has published more than 260 academic papers in relevant international journals and conferences, and more than 10 international and domestic patents. His article has been cited more than 14,100 times, with an H factor of 58 and a single paper with a maximum of 1500 times (according to Google Scholar). He was awarded the “10 Most Influential Paper Award” by IEEE PerCom 2013, the top conference in the field of ubiquitous computing.

All are welcome. ?
