Title: "A Survey on Contactless Human Sensing Using Radio Waves"

by

Mr. Zhiyang LI


Abstract:

Human sensing aims at measuring various aspects of human beings, such as 
activity, identity and location. Traditional methods for human sensing 
typically attach wearable devices to human body, which is intrusive and 
uncomfortable. Recently, some camera-based systems have been developed, 
but the use of cameras has raised privacy concerns. Furthermore, cameras 
can only work in Line-of-Sight scenarios. To avoid these defects, 
researchers resort to radio waves and have developed many contactless 
human sensing systems. These systems work by analyzing the reflected 
wireless signals from human body.

In this survey, we provide a detailed overview of the systems designed for 
contactless human sensing based on radio waves. We first introduce the 
background, motivation and intuition of radio wave based human sensing, 
and provide necessary preliminaries. Then we review the published systems 
categorized by their applications, including activity recognition, gesture 
recognition, fall detection, vital signs monitoring, sleep monitoring, 
authentication, localization, imaging and others. Finally, we conclude the 
survey and discuss some possible future directions.
