keywords: prevention of dementia, coimagination, multiscale service model, cognitive engineering, science of lethe Summary Purpose of this study is to explore sustainable service where continuous validation is possible through the development of support service for prevention and recovery from dementia towards science of lethe. We designed and implemented conversation support service via coimagination method based on multiscale service design method, both were proposed by the author. Interactive conversation supported by coimagination method generates social interaction so as to prevent progress of dementia. Multiscale service model consists of tool, event, human, network, style and rule. Service elements at different scales of tool, event, and human were developed according to the model. Firstly, we developed conversation interactivity measuring method in order to measure intensity of cognitive activities for prevention of dementia (event). Secondly, education program for learning coimagination method was designed and provided in order to bring out social intelligence of participants and instructors (human). Thirdly, relationship between social intelligence and prevention of dementia is discussed based on the experimental data (tool).
