As Eric von Hippel advocates that diversity is the source of innovation, it is crucial that wide variety of stakeholders and citizens participate in projects in living labs.In particular, in recent years the ecosystem of living labs has transcended national and regional frameworks, making it easier for stakeholders with ideas and background to gather.However, on the other hand, the fact is that diversity will make it difficult for people with different historical backgrounds, cultural contexts, and social affairs to communicate for the difference in preconditions.Therefore, there is a growing need for an information base that can encourage the active participation of stakeholders with different backgrounds, achieve better communication among participants, and encourage the co-creation of ideas and projects.
