Analysis of appropriate timing for information notification based on indoor user´s location transition

The purpose of this study was to explore the convenient timing for information notification of the users in their daily life. Using the location and the time interval since a location change, we have examined the features of the user´s response to information notification. For a period of three weeks, four subjects carried mobile terminals which randomly notified them about daily information. The obtained results showed that the responsiveness is high just before and after change of subject´s location. The responsiveness decreased with the increase of the time interval since a location change. The change of the responsiveness differed with the subject location and its change through time was symmetric for the time intervals before and after the location change. An effective control of the notification timing could be obtained using the information about the user´s location and the time interval since the change of user´s location
