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.


Jun Kato is a HCI senior researcher at AIST, Japan, and also serves as a technical advisor at Arch Inc. He worked for Microsoft and Adobe and received a Ph.D. from The University of Tokyo in 2014. He has focused on PX research, founded SIGPX, and regularly gained academic recognition such as ACM CHI 2013/2015 Best Paper Honorable Mention.

Recent updates

Will lead the featured session titled R&D for Anime Production: State-of-the-Art and Future Prospects and also serve as the Real-Time Live! Chair at ACM SIGGRAPH Asia 2021.
Participated in the German anime and manga convention Connichi and presented in the panel session "How Academics Contribute to Anime's Future" -- glad to be in Germany (virtually), my country of birth!
Presented Past, Present, and Future of Storyboarding in Japanese Animation in the Anime session of SAS 2021. This is the first full-length oral presentation as Arch Research!
Served as an Associate Chair for the EIST subcommittee and the Student Research Competition Co-chair at ACM CHI 2021. Congratulations to the winners (see the bottom of the Awards page)!
Gave an invited talk titled "Creativity Support for People with Diverse Technical Background" and presented a poster on the ongoing project for Japanese animation storyboards from Arch Research at ISID 2021, which got one of the Best Poster Awards!

Research topics

While I am interested in broad area of HCI and have a high-level goal of supporting people's creativity, I have been especially focused on the following topics. For the list of concrete projects, see Projects.

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.


Please reach me via email or social networking services rather than telephone and facsimile when possible. I rarely check these conventional machines.
