About Our Lab
Research Fields
Our laboratory explores socio-technical systems in which people, technology, organizations, and environments interact. Drawing on ergonomics, safety engineering, and healthcare management, we aim to contribute to safer and more reliable systems. One of our core themes is safety management in safety-critical domains. Accidents and incidents are not caused by human errors alone. They often emerge from interactions among multiple factors, such as team coordination, information systems, and organizational culture. We focus on these underlying factors and their relationships to support the design of safer and more dependable socio-technical systems.
In healthcare, our recent work addresses patient safety issues associated with the internationalization of healthcare workers. We also focus on emerging safety challenges related to digital healthcare, such as electronic health records (EHR) and telemedicine. In addition, we use large language models (LLMs) to review incident reports and patient feedback, exploring AI as a collaborative tool that supports human judgment. Our work also extends to safety-critical domains beyond healthcare. These include railway and traffic safety, as well as VR-based safety training. Although the application domains differ, our perspective remains consistent that safety issues should be understood through the interaction between human, task, environment, technology, and organization.
Another important area is human-centred design for an aging society. We address older adults’ health behaviours, their use of technologies, and differences in technology acceptance between younger and older adults. We also participate in the international collaborative project “Later Life Workplace Index” (LLWI), which examines organizational practices and support systems for multi-age workplaces. Rather than viewing older adults simply as those who need support, we aim to help create environments where they can continue working safely and healthily while making use of their experience and strengths.
We also apply ergonomics to UX in daily life and service contexts. Our work covers social networking services (SNS), online services, and other user-centred systems, with attention to users’ characteristics and behaviour. Depending on the topic, we combine methods such as eye-tracking, questionnaires, interviews, behavioural experiments, wearable data, and natural language processing (NLP).
Overall, our laboratory connects safety-critical domains, human-AI collaboration, work in an aging society, and UX design. From a human-centred perspective, we aim to contribute to social systems that are safe, reliable, and easy for everyone to use.
