Elements of Visible Light Communication Research

Hsin-Mu Tsai, National Taiwan University


Visible light communication (VLC) has gained great attention from both the industry and the academia as it can potentially provide a solution to alleviate the congestion in the wireless spectrum, offloading the ever-increasing data traffic to the untamed optical spectrum while taking advantage of the pervasive lighting infrastructure. On the other hand, what is less obvious is that VLC has many unique characteristics which can in fact allows it to provide better support to existing applications or enable new applications, compared to its RF siblings.

In this talk, I will touch upon a number of interesting elements in the latest research in the field: using cameras as a VLC receiver to enable pervasive augmented reality applications, alleviating traffic congestion on the roads and in the communication channels at the same time with vehicular VLC, and taking advantage of the invisible changes in visible light - light's polarization. I will close the talk by illustrating a number of open research problems and the roads ahead.


Hsin-Mu (Michael) Tsai is an associate professor in Department of Computer Science and Information Engineering at National Taiwan University, Taipei, Taiwan. He received his B.S.E in Computer Science and Information Engineering from National Taiwan University and his M.S. and Ph.D. in Electrical and Computer Engineering from Carnegie Mellon University. Dr. Tsai's recognitions include 2015 K. T. Li Young Researcher Award, 2014 Intel Labs Distinguished Collaborative Research Award, 2013 Intel Early Career Faculty Award (the first to receive this honor outside of North America and Europe), and 2013 National Taiwan University's Distinguished Teaching Award. He has served as TPC co-chairs for ACM CarSys 2017, IEEE Vehicular Networking Conference (VNC) 2016, ACM VANET 2013, and as a founding co-chair for ACM Visible Light Communication System (VLCS) Workshop in 2014. His research interests include vehicular networking and communications, intelligent transportation systems, visible light communications, and wireless channel and link measurements.
