2. Background of research concern sourceWomans conscious for aging and lifestyles survey, 2012N=1,114 Ideal Body Shapeslimming waist-line 88.9 Dairy actions for beauty and health Walking or jogging 33.6 Not sports type physical moves 27.2 Dietary control 14.5 sourceJapan National Survey for health and nutrition But, Population rate of fat and obese have been keeping steady 2013/08/25 Suda Yasuji Cause of fat and obese is clearly simple Strong Needs for diet(good shape) Actions for diet are relatively week Male age20-60s Female age20-60sFemale age20s of under BMI 15 Population rate of BMI 25 and more(2001-2011) 3. Focus of research area fat taxes implementation city design policy change relating research on population approach research on adherence for regimen intrinsic motivation incentivespoints and badges personalized services interaction platforms 2013/08/25 Suda Yasuji Behavioral change in diet personal desire social desire social environment personal environment intrinsic motivation incentives environment al design A environment al design B optimization of medical approach 4. Definitions of commodity/commoditized No quality differences among producers ex.petroleum, mobile phones by investopia Advancing standardization and technologies, growing market, and maturating lifecycles cause difficulties in differentiation essential aspect of products and services by marketing Wiki, JAMA Products and services that are easy to buy, thin profit and no competitive feature except price by Merriam-Webster dictionary 2013/08/25 Suda Yasuji Diet support devices such as pedometer and weight scale are in a state of commodity Premises of research Diet support devices are commoditized 5. Premises on research Diet support devices are commoditized Data about penetration rates of diet support devices Owning rate of Pedometer (Survey by Aichi prefecture, 2012) Owning and usage Rate of diet support devices (Survey by i-cube company) Rate of measuring weight monthly (National survey for health and nutrition ,2011) 2013/08/25 Suda Yasuji N1,884 20s 30s 40s 50s 60s Male 12.1% 16.4% 17.2% 21.5% 38.0% Female 14.4% 15.6% 21.7% 25.9% 41.5% N185,Female own&use own&no use not own Thermometer 75.7 20.5 3.8 Weight scale 45.4 12.4 42.1 Weight & body composite scale 48.6 10.3 41.1 pedometer 14.1 35.1 50.8 N7,877 20s 30s 40s 50s 60s Male 71.5% 78.4% 85.4% 78.8% 81.1% Female 88.8% 88.4% 78.8% 87.7% 90.2% 6. Diet Support devices have been challenging to be product service systems combining with ICT 2013/08/25 Suda Yasuji2013/02/10 Product Service free Pay for use Pedometer,weight- scale,mobile phone app. Premises on research Diet Support devices as Product Service Systems 7. Co-creation and feedback loops measure&record release&share feedback adjust action 2013/08/25 Suda Yasuji Feedback loops are critical component of co-creation in diet support type product service system weight scale pedometer others community portal expertiseservice providers) buddy in community behavior change 8. 2013/08/25 Suda Yasuji I set 2 research questions in terms of understanding the actual condition relating to co-creation process in diet support service with ICT Research Questions RQHow far does user perceive and accept the feedback system (feedback loop) of diet support type product service systems ? RQWhat does user think about interaction with other users, and use for behavior change ? (Are there robust interaction network ?) 9. Previous Research Reviews Experimental verification of healthcare improvement service based on continuous lifestyle monitoring and behavior changeMiyagi Univ., 2009 focusing on emotion of user based on Trans Theoretical Model (TTM) referring feedback loop only in terms of its mechanism (how it works) Examination of mental factor that affect the adherence volition of physical exercise Nakamura and Furukawa, 2004 focusing on psychological factor of individual motivation such as extrinsic/intrinsic motivations using POMS (Positive Mood Scale) to measure motivational factors, concluding fun and capability are important factor for sustaining behavior change in exercise programs Motivation, self-determination, and long-term weight control Teixeira,Perdo J.,et al, 2012) reviewing motivation and behavioral change researches. insisting effectiveness of self determination theory(SDT) and advancing research relating to motivation in terms of its quality aspect 2013/08/25 Suda Yasuji 10. Meaning of this research 2013/08/25 Suda Yasuji Process and co-creation research about diet services Product Service System about diet services For these points, I may contribute to enrich co-creation and behavioral change research relating to diet services Many researches focusing on motivation and incentives are already conducted, although researches focusing on service process and co-creation are not. Researches on diet services mainly conducted in exercise or medical intervention categories so far. On the other hands, researches in term of product service system are not. 11. Data for analysis user group sex age recorded days object Karada Scan users 24 users registered M 46 46 F 52 7 F 30s 6 Diet using pedometer 48 users registered M blank 49 F blank 31 F blank 72 run&walk diet challenge 13 users registered M 37 5 F 28 17 2013/08/25 Suda Yasuji Picked up 8 objects from users of registered courses of goo Karada-log. 3 courses are randomly selected by course description which include using weight scale, pedometer, and mobile phone application Total number of registered users in goo Karada-log 188,933 as of May 2013 12. Scheme of Analysis Total 233 days data from 8 users statistic analysis Using natural language analysis software kh coder transform description in diaries into text form (on the right) Then create collocation network and dendrogram of extracted words for analysis qualitative analysis Read diaries and created profiles of 8 users respectively first, then found common characteristics more than 2 users 2013/08/25 Suda Yasuji Compiled text data for kh coder 13. 2013/08/25 Suda Yasuji Results of Statistic Analysis Collocation network Extracted words and connection between words are displayed 14. 2013/08/25 Suda Yasuji Results of Statistic Analysis words total weight fat calorie walk steps walking balance lunch body supper Number of occurrences of extracted word dendrograma part diet is not so often mentioned in diaries 15. 2013/08/25 Suda Yasuji Findings of Qualitative Analysis Sustainability of behavioral change is so hard. Lose and get weight processes are cyclic. In daily life, assigning time for diet activities or controlling calories of foods are strongly constrained. Feedback loops are not mentioned. Thus how diet support information function through feedback loops is not clear Not all user but some, user-user interactions within information network communities are drivers for sustaining diet activities Knowledge about diet are based on former experience and conceptual do exercise do not eat level 16. Examination of Research Questions RQHow far does user perceive and accept the feedback system (feedback loop) of diet support type product service system ? Users do not pay attention to feedback system of diet support type product service systems are showed both statistic and qualitative analysis RQ What does user think about interaction with other users, and use for behavior change ? (Are there robust interaction network ?) Through qualitative analysis, user-user interaction work as sustaining driver for diet activities but it occur only in a few user 2013/08/25 Suda Yasuji 17. Implications Theoretical implications There are some dysfunctions in co-creation process, especially feedback loops, of diet support service with ICT through usage investigation. Behavior change models which are used in diet support service with ICT do not perform their effectiveness as there are very faint ties between user conscious and user action. Business implication Feedback loops should be redesigned from merely data and communication platform to recorded data driven behavior change support platform. 2013/08/25 Suda Yasuji 18. Limitations and Expectations In this research, I described a state of co-creation about diet support service with ICT from users perspective 2013/08/25 Suda Yasuji limitationsanalyzed data are text data described as diaries which released on the internet. This means that user information which are not written in diaries do not clear. So, deeper analysis for why they write this phrase are out of the sight. expectationsMore deeper analysis of user and adding analysis of service providers may contribute to better understanding of co-creation process and service design for diet support service with ICT. 19. Research impression There are relatively small users of diet support service with ICT at present 1. One of 2 research questions are loosely supported. There may be an opportunity to get robustness for research questions gathering more user data and analyzing them. 2. Furthermore, assuming todays users as lead user may have a chance to understand co-creation, lead user innovation, and more attractive service design. 2013/08/25 Suda Yasuji 20.
