The application of wireless sensor network technologies to everyday life situations still remains highly unexplored.
To enable such applications, a new breed of sensor networks needs to observe and interpret the behaviors of people
in physical space and autonomously react to provide services. Furthermore, they are expected to do so with low
latencies and without invading the privacy of their users. In this talk, I will describe a new sensor network
architecture, the BehaviorScope, which aims to parse out human behaviors through sensor observations. A framework of
probabilistic grammars used to transform low-level sensor data to high-level semantic interpretations. Our focus is to
detect behaviors without tagging people with sensors. For this we are developing a custom image sensing modality that
provides accurate motion information without revealing any image information. This modality and its application in an
assisted living testbed will also be described.
Andreas Savvides is an Assistant Professor in the Electrical Engineering and Computer Science Departments at Yale
University. He is the founder of the Embedded Networks and Applications Lab (ENALAB) that specializes in the design and
implementation of distributed sensor networks and smart spaces. Dr. Savvides completed his Ph.D. in the Electrical
Engineering Department at UCLA in 2003. Before this he earned his B.S in Computer Engineering from the University of
California, San Diego and an M.S in Electrical and Computer Engineering from UMASS, Amherst. During his graduate studies
he has been a member of the Networked Embedded Systems Lab (NESL) and the Center for Embedded Networked Sensing (CENS) at
UCLA. Prior to joining UCLA, he worked for 6 months as a researcher in ad-hoc networks at the HRL Labs in Malibu, California.
Dr. Savvides’ research is supported by an NSF CAREER award, other NSF grants and industrial support. Dr. Savvides is also a
member of the Sensor Networks Consortium at Boston University.
