Doctor of Engineering. Joined the Industrial Product Research Institute, Agency of Industrial Science and Technology in April 1986. Engaged in the researches for tactile perception, brain mechanism for sensory-motor integration, computer input device, ITS human interface, and car driving behavior. Currently, director of the Human Technology Research Institute, AIST. Professor of the Cooperative Graduate School, Tsukuba University. In this paper, reviewed the comparison and relevance to other researches to position this research in the field of synthesiology, and constructed the whole structure of the paper.Discussions with Reviewers1 Emphasis of the authors’ thoughts and actionsComment (Akira Ono, AIST)This is an extremely interesting research, and it seems that the authors are creating a new discipline in synthesiology. On the other hand, I feel that the descriptions in this paper are rather explanatory and plain. I think the reader can better understand the significance of the research in terms of synthesiology if you emphasize your thoughts and actions, like what intentions the authors had, what they selected, and what they determined.Answer (Motoyuki Akamatsu)This paper not only recapitulates the research that we have been doing as synthesiology, but was written with an objective of positioning this research, while trying to define the overall picture of synthesiology. We tried to position our research by reviewing researches aiming to connect products to human users, and therefore, it has become rather explanatory. We revised some of the expressions to clarify our statements. 2 Verification of the cognitive chrono-ethnography methodQuestion (Akira Ono)There are two interesting case studies of the cognitive chrono-ethnography (CCE) method, and the results are steadily being accumulated. On the other hand, I understand that you have not yet gotten to the point where you have done verification by obtaining user evaluation after applying the results to the design of car navigation and baseball game programming. Am I correct? Also, how do you test and evaluate the research results of whether the past CCE research method was adequate or inadequate? Question (Masaaki Mochimaru, Digital Human Research Center, AIST)I found that the method of this research has analogy to the idea of process standard in the sense that the quantitative verification is not discussed. In process standard, the procedure and the method to check the procedure are standardized, and that whether the procedure is carried out properly can be confirmed.Moreover, a person other than the one who created the process can execute it. Analogically concern, can this CCE method be replicated by anyone if the procedure is followed? Answer (Motoyuki Akamatsu)We need more time for product development based on the result of this research. Thus, as you indicated, we have not reached the state of evaluation by actual users. From the standpoint of the verification being the acceptance of technology and service by society, I must say that it has not been verified yet.Muneo KitajimaCompleted the master’s course at the Department of Physics, Graduate School of Engineering, Tokyo Institute of Technology in 1980. Doctor of Engineering (Waseda University, 1986). Joined the Industrial Product Research Institute, Agency of Industrial Science and Technology in April 1980.
