Earlier this year, Mercari R4D Researcher Miyuki Fujiwara received the Interactive Presentation Award at INTERACTION 2025. The award-winning research was a joint effort shared between Miyuki Fujiwara, Ari Hautasaari (University of Tokyo Graduate School Project Associate Professor, Interfaculty Initiative in Information Studies), and Rintaro Chujo (University of Tokyo Master’s Student, Graduate School of Interdisciplinary Information Studies). The three are members of the Value Exchange Engineering project, a comprehensive partnership program between Mercari and the University of Tokyo.

Presentation summary
The presentation examines a current marketplace app that has implemented a feature for creating item descriptions through collaboration between human users and AI technology by leveraging large language models (LLMs). The purpose of this feature is to reduce the burden on sellers when inputting item descriptions. This research examined two things: 1) whether item descriptions created with the assistance of an LLM would impact buyers’ item selection preferences and to what degree they regard the item listing as honest; and 2) how user behavior would be impacted by the presence or absence of labels stating that a product description was either created entirely by AI or by a user in cooperation with AI.
What is INTERACTION 2025?
INTERACTION is a symposium held every year since 1997 by the Special Interest Group on Human-Computer Interaction of the Information Processing Society of Japan, which is an academic information processing institute, and other such organizations. The symposium is a venue that brings researchers and professionals together under the same roof to share and discuss the latest information related to interaction pertaining to the computational sciences such as user interfaces, CSCW, visualization, input/output devices, virtual/augmented reality, ubiquitous computing, and software engineering as well as the humanities such as cognitive science, social science, anthropology, media theory, and art.
