Profile

Riku has been a Ph.D. student at Human-Computer Interaction Institute (HCII), School of Computer Science, Carnegie Mellon University since 2021.08. He is advised by Dr. Mayank Goel and working on applied machine learning with a focus on health sensing. Before coming to CMU, he received his B.E. and M.S. from The University of Tokyo, Japan, where he worked with Dr. Hiroshi Saruwatari on real-time voice conversion using DNN, and Dr. Masahiko Inami on auditory intervention for behavioral change.

In a nutshell, he's passionate about human-computer interaction (HCI), human-AI interaction (HAI), and, after a long day, occasional human-beer interaction (HBI).

Research

I develop adaptable, intelligent agents to support and affect users in the physical world with multimodal sensing techniques and human-AI interaction perspectives. I achieve this by smartly digitizing user information (pose, gesture, gaze, activity, speech, etc.) and designing helpful intervention with practical devices, such as smartwatch. I investigate the following research questions:

  1. how we develop reliable AI systems from imperfect sensing and machine learning [Health / Well-Being]
  2. how we enable computers to deal with communication contexts that are ambiguous and highly human [Social Signal Processing]
  3. how we augment our ways to interact with computers [Interaction Technique]

My inventions have been licensed to several companies in diverse fields such as executive coaching, sales enablement, online classroom, human assessment, and entertainment. I leverage such collaborations to study the actual deployment process of AI systems as an external researcher (e.g., AI for Human Assessment [W.7], Coaching Copilot [C.19]).

Talks

I am willing to have talks, especially to (junior) high school students. This comes from my personal experience of having been exposed to the joy of science and technology at seminars I attended when in high school.
