Human-Computer Interaction researcher, Ph.D.

Research area

I am interested in broad area of Human-Computer Interaction (HCI), and have been especially focused on designing user interfaces and integrated environments for creativity support. Improving Programming Experience (PX) is an important subgoal to support the creativity of people with diverse technical backgrounds.


He is a Senior Researcher at AIST and the Technical Advisor (PI) at Arch Research with a focus on PX and creativity support research. Since April 2024, he has been a Visiting Scientist at Ex-Situ group, LISN, Université Paris-Saclay. He received a Ph.D. from The University of Tokyo (2014) and has regularly gained academic recognitions such as Honorable Mentions at ACM CHI (2013, 2015, 2023) and IPSJ/ACM Award (2021).

Recent updates

Started my sabbatical-like year as a Visiting Scientist at Université Paris-Saclay. I belong to Ex-Situ and conduct research on methods and tools for creativity support.
Concluded the "AIST Creative HCI Seminar series" with the sixth edition, focusing on "HCI research in the wild", inviting Jennifer Jacobs and Koya Narumi.
Served as Co-chair of LIVE 2023 and had a great time — thanks to everyone who was involved in the workshop.
Added a summary of the Japanese tutorial course titled "Introduction to Live Programming: Try It, Make It, Know It" held as part of The 40th JSSST Annual Conference to the page "User Interfaces for Live Programming".
My resume has been outdated for a while, and I finally managed to update it.

Research topics

Creativity Support Environments

To realize a creative society in which people want to create content with the help of AI technologies, a sustainable ecosystem in which content inspires the next creation serves a critical role.

I shed light on the creative culture in such an ecosystem, build a "creativity support environment (CSE)" that supports the content creation and distribution process, and aim to establish Human-Computer Interaction (HCI) technologies that engineer, nurture, and maintain the creative culture.

Programming as Communication

Programming should be a more social activity than what it is right now. A programming environment does not need to be only for programmers. It should instead be designed for users with diverse technical backgrounds.

Such inclusive design enables the users to communicate with each other through programming-related activities, delivers benefits of programming to all of them, and would give empowerment to them.

User Interfaces for Live Programming

Live programming eliminates the gulf between code and execution. User interface design plays the key role in providing live programming experience.

With appropriate user interface design, live programming can potentially benefit end-users, be used for applications whose computation takes a long time, and mean much more than merely providing real-time information of the running program.

Programming with Examples

The programming-with-examples (PwE) workflow lets developers create interactive applications with the help of example data. It takes a general programming environment and adds dedicated user interfaces for visualizing and managing the data.

This is particularly useful in developing data-intensive applications such as physical computing, image processing, video authoring, machine learning, and others that require intensive parameter tuning.
