We work with partners in industry, government, communities, and the field
to design services and their ecosystems.

The lab began as an interdisciplinary design lab that brought HCI and service design together across academic fields, and it has grown into the Transdisciplinary Design Lab, which works from real problems with partners outside the university, such as companies, local governments, residents, and cooperatives. Our theoretical lenses are service-dominant logic (S-D logic), which holds that value is not delivered by firms but co-created by the people who bring their knowledge and skills together, and HCI, which designs and evaluates the interaction between people and technology. Our methods are human-centred design (HCD) and qualitative research. Our subjects range widely, from robots entering care and hospital settings, blockchains entering local communities, and generative AI entering professional work, to spaceports arriving in rural regions and resources discarded in developing countries. What they share is the view that acceptance and value are decided not by the nature of a technology or material but by institutions (rules, customs, and meanings).

For industry and government →We set out the roles the lab can play and the value we propose, together with forms of collaboration such as joint research, contract research, and student projects.
For students →For those considering the seminar or graduate study, we explain what you can do here, whom we are looking for, and how supervision works.

01 — ResearchResearch

Across six themes, we study how new technologies, ventures, and resources are accepted and become valuable when they enter the field.

Turning unused resources and waste into value
Ongoing

A Value Study of Discards: unused resources in the Philippine coconut industry

Taking mature coconut water discarded in copra production as the case, four disciplines (service design, cultural anthropology, fermentation science, and ICT4D) examine the proposition that what separates waste from resource is not the nature of the material but the way society looks at it.

Designing service-robot deployments in care facilities, hospitals, and facility management

At three sites we took stock of regulative, normative, and cultural-cognitive institutions, selected the jobs that could be entrusted to robots, and implemented and evaluated services within two months. We compare deployment strategies across sites with different institutional complexity.

Local DAOs and collaboration between digital and physical residents

We interviewed 22 community managers, digital residents, and physical residents across five local DAOs and analyzed the socio-technical gap between blockchain governance and place-based community practice. We also developed and evaluated service design tools that reflect the philosophy of Web3.
