propose a positioning feature-aware hybrid positioning method, which is essential to realize energy-efficient geofencing by integrating existing energy-efficient positioning technologies. Existing energy-efficient technologies, which are composed of movement detection, variable interval positioning, and hybrid positioning, are mutually complementary in providing synergetic effect of power reduction. Meanwhile, network-based positioning which is utilized in hybrid positioning produce positioning results with only low level of geographical resolution, which often results in concentrated positioning results in one place. Such positioning feature has negative impact on accuracy of movement detection function. In this paper, in order to eliminate this impact, we propose a hybrid positioning method that switches positioning measure to GPS when network-based positioning shows dubious positioning results. We implemented the proposed method on Android-based smartphone, and confirmed through field test that the proposed method realizes energy-efficiency while maintaining entrance detection accuracy.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1600","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1590","bibliographicIssueDates":{"bibliographicIssueDate":"2016-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"57"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":169476,"links":{}}
