Keita Higuchi, Ph.D. 樋口啓太 博士(学際情報学)

About

Keita Higuchi is Lead Research Scientist at SB Intuitions and a co-founder at Jokun Brewing Lab. He received his B.A. degree in Kanazawa Institute of Technology. He also received his M.S. and Ph.D. degree in the University of Tokyo. He was supervised by Prof. Jun Rekimoto at Rekimoto Lab on Human-UAV interaction projects which won a Emerging Technologies Prize at ACM Siggraph Asia 2012. He joined Multimedia, Interaction, and Communication (MIC) group, Microsoft Research Redmond as a research intern student twice on the Viiboard Project that his paper was accepted by CHI 2015. He was working with Prof. Yoichi Sato on the CREST project as a Project Research Associate/Lecturer at Institute of Industrial Science. The project focuses on understanding group attention and activities by analyzing information gathered from multiple wearable devices, such as wearable cameras and eye trackers. He was also Researcher at Preferred Networks to lead the HCI for ML projects. He is interested in remote collaboration and video browsing interface studies that the papers were published in CHI 2016, CHI 2017, and IUI 2019 respectively. He is also actively working on accessibility technologies for people with disabilities (e.g. blind, and ASD) that the paper was accepted to IUI 2018, CHI 2019, and CHI 2020. His recent work focuses on human interaction with machine learning and large language models, including role-playing agent development and debugging (IUI 2025), personalized recommendation (CHI Extended Abstracts 2025), and interactive Deep Research (WISS 2025). He also studies interactive 3D reconstruction and annotation, with publications at IUI 2025 and in IEEE Computer Graphics and Applications (2026).
