This is Hsin-Mu (Michael) Tsai's homepage. I am an associate professor in the Department of Computer Science and Information Engineering and Graduate Institute of Networking and Multimedia at National Taiwan University. I lead the Mobile and Vehicular Network Laboratory in my department. I am also the Principal-Investigator of the project “Next-Generation Camera Communications” in the NTU IoX Center.

CELLI, POLI paper accepted by MobiSys 2017

Our recent works “CELLI: Indoor Positioning using Polarized Sweeping Light Beam” and “POLI: Long-Range Visible Light Communications Using Polarized Light Intensity Modulation” are both accepted as full papers in ACM MobiSys 2017! ACM MobiSys is a highly selective international top conference in the computer networking and systems area. This year the acceptance rate is 34/188 = 18%. MobiSys'17

LiCompass paper accepted by INFOCOM 2017

Our recent work “LiCompass: Extracting Orientation from Polarized Light” is accepted by INFOCOM 2017 as a full paper (acceptance rate = 292/1395 = 20.93%).

Serving as TPC co-chair of IEEE VNC 2016

I am serving as TPC co-chair of IEEE Vehicular Networking Conference 2016 [web], which will be held on December 8-10, 2016, in Columbus, Ohio, USA. Please consider joining us at the conference.

K. T. Li Young Researcher Award

I received the 2015 K. T. Li Young Researcher Award from Institute of Information and Computing Machinery in Taiwan, for contributions in visible light communications, vehicular networking and communications, and vehicle and transportation systems. Chinese

Research Project with Ford North America

Ford North America announced their international collaboration with my research group, putting together a joint effort to mitigate traffic congestion using cars' LED lights. The news can be found on NTU website English Chinese.


I am currently looking for brilliant students (all levels: undergraduate, master, and phd students) who would like to work on interesting research problems and to have hands-on experience on useful experimental research tools such as software defined radios, embedded systems for quick prototyping (Arduino, Raspberry Pi, etc.), LIDAR, cameras, etc., to join my lab. The main research direction of the lab is to solve real-world problems (often in the vehicle and transportation domains, but also for mobile and indoor applications) with communication and networking system designs. We deepen our understanding of the problem through quick prototyping and carry out measurements in the real-world. Then the design idea is again realized and validated with system prototyping.

Ongoing research projects (March 2017) include:

  • Traffic shockwave mitigation with vehicle-to-vehicle visible light communications (sponsored by Ford North America)
  • Next-generation camera communications (sponsored by Intel Labs and Delta Electronics)
  • Centimeter-level indoor visible light positioning (sponsored by Intel Labs and Delta Electronics)
  • Parking management in urban areas with software defined RFID

The potential students are encouraged to schedule a meeting with me via e-mail. I can explain these topics in details when we meet.

Research Interests

  • Visible light communications and positioning
  • Vehicular networking and communications
  • Vehicle and transportation systems (smart traffic light, parking management, traffic flow regulation)
