Ubiquitous Sensing Using Visible Light

Xia Zhou, PhD
Assistant Professor
Department of Computer Science
Dartmouth College
Hanover, NH

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.

Lighting Enabled Systems and Applications: A Vision Way Beyond Seeing

LESA: A Vision Way Beyond Seeing, an article which appeared in the May 17, 2016 online edition of West Coast Lighting Insider, highlights the work of the ERC.  In the future, personalized lighting will interact with our presence, our environment and our activities. Lighting will change color, brightness and directionality, all the while transmitting data to our cellphones and wearable tech, networked with the Internet of Things (IoT). Implementing this vision is the purpose of the Smart Lighting Engineering Research Center, newly rebranded as the Lighting Enabled Systems & Applications Engineering Research Center (LESA ERC).

LESA RPI faculty, Prof Partha Dutta in collaboration with Ram Krishna Dharmath Foundation University (RKDF), in Bhopal India, have developed a device that can surpass 1400 Celsius from insolation to produce electricity.  This project was sponsored from the Ministry of New and Renewable Energy, Government of India.  Varsity vice chancellor VK Sethi  and Professor Dutta developed the device.  The objective of this project was to achieve the greatest amount of energy from the sun to be used for the production of electricity, without the polluting effects of coal – the primary source of electricity right now.

Brian Frey, LESA graduate student of Prof Lin in Physics has been awarded the Dr. Paul S. Ho ’65 Graduate Prize in Physics.  This prize, established by the generosity of Dr. Paul S. Ho ’65, recognizes the need for technically educated people who will serve the betterment of mankind through the “application of science to the common purposes of life”. The fund shall be used to financially support a prize for an outstanding graduate student enrolled in the Department of Physics.

Frey is studying orders-of-magnitude absorption enhancement in simple cubic metal-oxide photonic crystals for mesoscale light-trapping applications.  He expects to graduate in the Fall 2016.

The University of New Mexico (UNM) has fabricated triangular-nanostripe core–shell semi-polar III–nitride light-emitting diodes (TLEDs) on c-plane sapphire [Ashwin K. Rishinaramangalam et al, Appl. Phys. Express, vol9, p032101, 2016]. The performance results are described as “preliminary”.  By using triangular nanostripes with semi-polar sidewalls, the UNM researchers hope to access the advantages for light-emission without the non-commercial costs of free-standing substrates and at a lower cost, which could accelerate commercial adoption.
