Proceedings of the 4th ACM Workshop on Visible Light Communication Systems, 2017
We present our efforts to design the first Visible Light Sensing (VLS) system that consumes only tens of μWs of power to sense and communicate. We achieve this by designing a sensing mechanism that uses solar cells to achieve sub-μWs of power consumption for sensing. Further, we devise an ultra-low power backscatter-based transmission mechanism we call

Proceedings of the 10th international conference on Mobile systems, applications, and services, 2012
We propose UnLoc [1], an unsupervised indoor localization scheme that bypasses the need for war-driving. Our key observation is that certain locations in an indoor environment present an identifiable signature on one or more sensing dimensions. An elevator, for instance, imposes a distinct pattern on a smartphone's accelerometer; a specific spot may ...

Extended Abstracts of the 2018 CHI Conference on Human Factors in Computing Systems, 2018
This demonstration presents BioFidget, a biofeedback system that integrates physiological sensing and display into a smart fidget spinner for respiration training. We present a simple yet novel hardware design that transforms a fidget spinner into 1) a nonintrusive heart rate variability (HRV) sensor, 2) an electromechanical respiration sensor, and 3 ...

Proceedings of the 12th annual international conference on Mobile systems, applications, and services, 2014
The goal of this work is to develop a new autonomous capability for remotely deploying precisely located sensor nodes without damaging the sensor nodes in the process. Over the course of the last decade there has been significant interest in research to deploy sensor networks.
