Contactless Human-centered Sensing: A Survey

PhD Qualifying Examination


Title: "Contactless Human-centered Sensing: A Survey"

by

Mr. Wentao XIE


Abstract:

Recent years have seen the surge of various wireless sensing technologies. 
Acoustic and WiFi signals are two kinds of wireless signals that are 
ubiquitously available in our daily lives. Leveraging these signals to 
perform sensing requires no dedicated hardware and it is easily integrated 
into the existing hardware. Therefore, acoustic-based sensing and 
WiFi-based sensing receive great attention from researchers. In this 
survey, state-of-the-art contactless human-centered sensing systems that 
use acoustic and WiFi signals are reviewed. We group the related works 
into the following six categories in terms of their applications: (i) 
device-based tracking and localization, (ii) device-free tracking and 
localization, (iii) human activity recognition, (iv) healthcare, (v) 
security and (vi) imaging. For each application, we compare the system 
design and performance between acoustic-based systems and WiFi-based 
systems, and we identify the research gaps in each of these topics. At the 
end of this survey, we draw a conclusion of this survey and point out the 
future research directions.
