2. healthcom2008 Agenda Introduction Application Model The MUSS Application Platform Implementation Evaluation Conclusion Discussion Demonstration

3. healthcom2008 Introduction (1/4) Background –Mobile phones or devices are usual Cellular phones, smart phone, PDA, even laptops, … –Many portable and small-sized bio-sensors are available PPG/ECG, Thermometer, Fat, Blood-sugar, … –Many mobile u-Health Apps are also developed. Stress phone, mobile blood-sugar checker, …

4. healthcom2008 Introduction (2/4) Motivation –Current applications are focused on general patients –Such general applications cannot reflects patient’s specific situations or environments For example, if a patient interested only in abdominal obesity, measuring fat of arm, leg, face are not necessary. –Consequently, personalized applications are much preferred by the patients.

5. healthcom2008 Introduction (3/4) Motivation –In order to provide personalized applications for each patient, there are some problems Employing more software developers is not feasible economically. Software developers do not have professional knowledge in medical or healthcare.

6. healthcom2008 Introduction (4/4) Our Approach –Instead of software developers, let medical specialists can develop applications without software development knowledge with concerning personal situations. –In order to realize it, we have developed an application platform (MUSS) and a development tool (workbench).

7. healthcom2008 Application Model This application model consists of 5 phases Each phase provides various activities. –(e.g., In Sensing phase, there are PPG sensing, Fat sensing, Blood-sugar sensing, etc.) SRI BDI/STAI-S Sensing Data Analyzer Disease Decision Questionnaire Data Analyzer Direct Feedback CSI Contents Recommendation Products Recommendation Questionnaire Data Processing Disease Treatment User Feedback Sensing ECG/PPG Thermometer Fat Measurer … …

8. healthcom2008 The MUSS Application Platform (1/4) MUSS (Mobile U-Health Service System) –A platform for mobile u-health applications. –Consist of three layers Components layer –Component registration, discovery Process layer –Process design, execution, management Application layer –Application development, management, delivery –XML-based message exchange –All components are Web Service (W3C).

16. healthcom2008 Implementation (5/7) User Interfaces of Application Scenario Player (Smart-phone version)

17. healthcom2008 Implementation (6/7) Stress Application (example) –Sensing Bluetooth PPG sensor –Questionnaire SRI (stress response inventory) –Data Processing learning-based stress diagnosis framework (DCAP) –Disease Treatment Stress reduction contents recommendation –User Feedback Weight values adjustment

18. healthcom2008 Implementation (7/7) Sensing Activities Questionnaire Activities Data Processing Activities Disease Treatment Activities Stress Application Scenario

19. healthcom2008 Evaluation Application Developer –Allows developing applications without programming –Requires many components enough Application Scenario Player –Properly executed the application scenario –New Activity (for User-Interaction) is Required  Upgrade is Required

20. healthcom2008 Conclusion We designed and implemented a platform which enables medical specialists to develop personalized mobile u-health applications. The key idea is to provide higher level of abstractions to who are not capable of developing software. As a results, we confirmed that mobile u-health applications can be developed without programming on our platform.

21. healthcom2008 Discussion Future works –Lack support of sensors Currently only two sensors (Fat measurer and PPG sensor) –Lack of control-flows in application scenario Conditional branching iteration Parallel composition –Experiments in the field Experimented only in the laboratory. Further experiments should be take place with real doctors and real patients.
