LESA Seminar Series Presents
Ubiquitous Sensing Using Visible Light

Abstract

The ability to sense what we do and how we behave is crucial to help detect diseases, diagnose early symptoms of health issues, and foster healthier lifestyles. Existing sensing technologies, however, have significant drawbacks. They either are intrusive — we have to constantly carry or wear sensing devices  (e.g., Apple Watch, Fitbit), or present serious privacy risks by capturing raw images, or are limited in sensing granularity.

In this talk, I will present a radically different approach to unobtrusive human sensing, which exploits the ubiquitous light around us as a sensing medium that senses and responds to what we do, without requiring any on-body devices nor any cameras. I will first present LiSense, the first-of-its-kind system that reconstructs a 3D human skeleton in real time (60 Hz) using purely the light around us.  Empowered by Visible Light Communication (VLC), LiSense uses shadows created by a human body from blocked light to reconstruct the 3D skeleton. I will then present our recent effort StarLight, which advances LiSense by addressing several practical issues and pushes light sensing closer to practice. I will conclude with our ongoing work and future directions.
