10. 10 Research Background As Indoor Location Based Service (ILBS) attract attention, a great deal of research is on going. Some of the ILBS’s have already been put into practice for commercial and disaster. Ex) １） Navitime Navitime provides indoor and outdoor navigation service in Japan that is enable us to ride train efficiency and avoid traffic jam. ２） e911 Phone sends position data when people call an ambulance or fire engine. ３） Micello Micello provides indoor map of shopping mall through smart phone. Etc… 10 Navitime e911Micello

11. Situations of ILBS and Issue of Research Situations of ILBS 1)Most of these applications are dedicated to one specific building 2)No application can provide a service to handle any indoor environment in a standardized way. Issues of the Research 1)Building manager and users have to apply various software in order to manage and use ILBS 2)Change of the indoor environment does not reflect the ILBS applications. 11

12. 12 Example of Issues (As is ) If building owner try to watch behavior of user to analysis how many users are in his building, building owner can not analysis in one software. Because each user use each application that has each position database and application database. Too much setting User A User B User C Building owner A App. A app. DB B App. B app. DB C App. C app. DB input output

13. Research Purpose and Goal The Research Purpose Design Indoor Location Based Service Provider Platform (ILBSPP) ILBSPP can: 1) handle different applications in an integrated and standardized way. 2) change environment in an integrated and standardized way. 13

14. 14 Categorize the Research into current ILBS research service technology Application Security and Privacy Business Model Accuracy & Positioning Disaster Management Commercial Service DBMS The Research

15. 15 Rival in Previous Research Title is: “A comparison of GIS architecture for implementing indoor location-based service” Authors are: Valerio Vianello, Cristiano di Flora, Christian Prehofer, Their Aim is : ・ to extend the scope of GIS system. ・ to develop standards for indoor applications. What they showed are: ・ System Architecture that enable users to expand fusibilities of indoor applications. ・ how to use the map into existing indoor location based service. Issue, which are still remain, is: ・ how to mash up existing Indoor location based application into their system.

16. MoSCoW of the requirements The Research 16 ・ Survey ・ Categorize application into some part ・ Define user requirement ・ Develop System Concept ・ Develop prototype ・ Application Management ・ Using map ・ Survey ・ Categorize application into some part ・ Define user requirement ・ Develop System Concept ・ Develop prototype ・ Application Management ・ Using map ・ Develop APIs ・ Web Application ・ Develop indoor application by using new APIs ・ Reflecting function that change algorithm of application ・ Web Application ・ Develop indoor application by using new APIs ・ Reflecting function that change algorithm of application ・ 3D modeling ・ Outdoor Positioning ・ Indoor positioning ・ Modeling ・ 3D modeling ・ Outdoor Positioning ・ Indoor positioning ・ Modeling Must Should Could Won’t
