Στις 3/11/2017 δόθηκε ερευνητική ομιλία με τίτλο "Enabling Motion Detection on Commodity WiFi Devices using PHY Layer Information" από τον Καθηγητή Δημήτριο Κουτσονικόλα, Assoc. Professor, Computer Science and Engineering Department University at Buffalo, The State University of New York, ΗΠΑ)

Περίληψη ομιλίας:

Client motion detection in WLANs has the potential to both improve protocol performance and enable a number of novel applications. In this talk, I will discuss our work on leveraging wireless signals to enable human motion detection at different granularities on commodity WiFi devices. In the first part of the talk, I will present a scheme for detecting and classifying client mobility on the access point side by leveraging Channel State Information (CSI) and Time-of-Flight (ToF), and I will demonstrate how mobility-awareness can improve the performance of a number of wireless protocols. In the second part of the talk, I will introduce WiDraw, the first hand motion tracking system based on commodity WiFi cards. WiDraw harnesses the Angle-of-Arrival (AoA) values of incoming wireless signals at the mobile device to track the user’s hand trajectory without requiring the user to touch the device or use any external hardware. Using WiDraw, a user can draw arbitrary lines, curves, or even alphabetical characters, simply by hand motion in the air. I will also give an overview of other research projects in UB WiNS Lab.
