We are working together with our partners on research and development of to research and develop inclusive design[^1] and accessibility technologies. Mercari’s proprietary C2C marketplace app boasts a wide variety of users who have signed up for the service. In recent years, the number of Mercari users in their 60s or older has also been increasing[^2] and visually-impaired people has motivation to buy and sell[^3] . This project aims to define and test the challenges faced by users, including the advanced age and visually impairment face in their interaction with the C2C marketplace(that is, the interplay between these users and the system). To realize more accessible and inclusive e-commerce products through technology, we are researching the potential of multimodal interfaces in e-commerce, which replace conventional visual operations with audio, haptics, and gestural operations.
