EE Colloquium: Wireless and Mobile Sensing Applications with IoT

Abstract

Ubiquitous finger motion tracking enables a number of exciting applications in augmented reality, sports analytics, rehabilitation-healthcare etc. While finger motion tracking with cameras is very mature, largely due to availability of massive training datasets, there is a dearth of training data for developing robust machine learning (ML) models for wearable IoT devices with Inertial Measurement Unit (IMU) sensors. Towards addressing this problem, we present ZeroNet, a system that shows the feasibility of developing ML models for IMU sensors with zero training overhead. ZeroNet harvests training data from publicly available videos for performing inferences on IMU. In another project on wireless sensing, we show the feasibility of identifying liquids by shining ultra-wideband (UWB) wireless signals through them. The core opportunity arises from the fact that wireless signals experience distinct slow-down and attenuation when passing through a liquid, manifesting in the phase, strength, and propagation delay of the outgoing signal. Our results show that we can distinguish coke from diet coke or pepsi, whole milk from 2% milk, and distilled water from saline water by measuring the properties of the wireless signals.

About

The School of Electrical Engineering and Computer Science was created in the spring of 2015 to allow greater access to courses offered by both departments for undergraduate and graduate students in exciting collaborative research fields.

We offer B.S. degrees in electrical engineering, computer science, computer engineering and data science and graduate degrees (master's degrees and Ph.D.'s) in electrical engineering and computer science and engineering. EECS focuses on the convergence of technologies and disciplines to meet today’s industrial demands.
