Jun Kato
Human-Computer Interaction researcher, Ph.D. (Computer Science)

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.

Bio

Jun Kato is a HCI 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.

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.

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.

Projects

Below is the list of research projects, followed by the list of design and/or engineering projects. See Design for the design-oriented list of my projects.
