Hsin-Mu (Michael) Tsai - 蔡欣穆

Deputy Vice President for Academic Affairs

Professor, Computer Science and Information Engineering

National Taiwan University

Note: Some information can still be found on my old web site.

What I do

• Research: I enjoy designing and buidling prototypes and doing hands-on work by myself and with my students. Topics I am interested in include communications and positioning using light, sensing with mobile systems and within cars, and wireless communications and networking in general. See my research page.
• Industry Collaboration: I serve as associate director in both NTU IoX Center and Delta-NTU Joint Research and Development Center and have ongoing research collaboration with Intel Labs and Delta Electronics.
• Digital Learning: I spent a portion of my time leading a team at NTU’s Digital Learning Center to develop the university’s next-generation learning platform - NTU COOL. See a recent video about us!
• NASA: In 2012, I founded a team with mainly undergraduate students, called NASA (Network Administration and System Administration), to maintain the IT infrastructure in our department. Currently I am still teaching a course to train these students.
• NTU CSIE TRAIN: I am helping with the department’s information system training program opened to the public. We are in the progress of developing the blended (digital + traditional) learning curriculum.

CELLI - Indoor Positioning Using Polarized Sweeping Light Beams [MobiSys'17]

CELLI uses a single luminary to project a large number of fine-grained, polarized, yet imperceptible light beams to the ground for indoor positioning. The system can achieve a 2.7cm median 2D error.
