Sachi Mizobuchi

Sachi Mizobuchi is a visiting scientist of IML. She has more than 15 years experience in carrying out human factors research and design in the information technology industry and automotive industry.

Her research interest is on human machine/computer interaction (HMI/HCI), input methods, human perception, cognition, motor ability, usability of ICT devices/software, human-robot interaction (HRI), and user centered design (UCD). In IML, she is leading a project on driver distraction while interacting information in a car.

She has a Ph.D in media and governance (Keio university in Japan, 2005) with her research on input technologies for handheld devices, and an M.A. and B.A. in psychology (Waseda university, 1995, 1993) with her research on long-term memory retrieval. In addition to being a member of the Interactive Media Lab, she is a chief research scientist of Vocalage Inc., a University of Toronto spinoff company.
