“Internet of Acoustic Things (IoAT): Challenges, Opportunities, and Threats”

Thu May 30, 2019 2:00 PM

Location: LTS Auditorium, 8080 Greenmead Drive

Nirupam Roy
Professor, Department of Computer Science and UMIACS

The recent proliferation of acoustic devices, ranging from voice assistants to wearable health monitors, is leading to a sensing ecosystem around us—referred to as the Internet of Acoustic Things or IoAT.

My research focuses on developing hardware-software building blocks that enable new capabilities for this emerging future. In this talk, I will sample some of my projects. For instance, (1) I will demonstrate carefully designed sounds that are completely inaudible to humans but recordable by all microphones. (2) I will discuss our work with physical vibrations from mobile devices, and how they conduct through finger bones to enable new modalities of short range, human-centric communication. (3) Finally, I will draw attention to various acoustic leakages and threats that arrive with sensor-rich environments.

I will conclude this talk with a glimpse of my ongoing and future projects targeting a stronger convergence of sensing, computing, and communications in tomorrow’s IoT, cyber-physical systems, and health care technologies.
