System for Visualizing and Managing Relationality Assets as Trust Enabling Rebuilding of Communities

Toward rebuilding of a local community, we aim to quantify and visualize relationality between humans, `Mono' and `Koto' in a local community. Original ideas are to postulate relationality as assets that community people individually earn, and to elicit their awareness of relationality assets as trust. In addition, we aim to create a mechanism through which community people invest their relationality assets to relationality itself so as to increase their assets, so that they themselves can manage and sustain the mechanism. In order to investigate how to design the mechanism and verify its effectiveness, we have conducted field works with residents in a community for years. We acquired residents' activity data with smartphones lent to them in the community, and activity data means “location information,” “send and receive emails,” “telephones reception and transmission” and “passing-each-other data from Bluetooth. In this paper, we focus on research concept, scheme and approach of this research and discuss their significance based on some results of field experiments and simulations.
