This paper presents characteristics of “interactive” communication to promote innovation. In recent years, many researchers have shown interest in “interactive” communication in science and technology communities as a means of promoting innovation. However, collaboration and “interactive” communication do not guarantee success, which is dependent on the quality of the communication and the methods employed. This paper investigates the development of successful collaboration in the field of innovative technology. We examined the specific case of removing old paint using laser beams to elucidate an “interactive” communication method that promotes innovation. We conducted three in-depth interviews with key members of the development team and a group interview involving all participants and analyzed and interpreted the data using the framework of “Katari=Antenarrative” theory. As a result, the following factors were identified as characteristics of “interactive” communication promoting innovation: “chains of awareness and meaning transformation in a ternary relationship,” “Katari to create empathy,” “mutual responsiveness,” and “listener’s flexibility.” Furthermore, we brought up “Katari-tsutae” as a new concept of “Katari=Antenarrative” theory. In conclusion, we suggest that innovation will be promoted by recognizing and practicing these four characteristics of “interactive” communication when working on technology development.
