Research Abstract	In thisstudy we present an indoor mobile navigation system that assists users in shopping in a commercial complex. First, we arranged-dimtehnrseieonal geospatialinformation database for buildings and shops. We associated not only shops but also items with the egospatial coordinate with this database. Secondly, we developed an item search system that can be used for searching items and menus in the commercial complex. Finally,we developed an indoor mobile navigation system that can provide a route f’rosm the usercurrent location with -WFi positioning system to the shops which sell the items user selected on the floor maps of the building. Then, we conducted a verification experimentfor this system. The result of it was that this system is useful aenrds’affbeucytisng usbehavior. With this system, users can compare and reach the items they want easily without going around the various shops in the commercial complex.
