the location dependent information services, it is important to judge whether a user exists inside the specified area or not. But existing location detection methods based on signal strength of wireless access points are aimed to calculate the coordinates of the moible terminal with margin of error. Hence it is not accurate to judge a user existence inside area in many cases. Therefore in this research, we propose a novel existence judgement method that calculates geographical probability distribution according to thesignal strengths. Our method can realize high accuracy since it can make use of existence probabilities that is abandoned in existing methods.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告電子化知的財産・社会基盤（EIP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-11-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"24","bibliographicVolumeNumber":"2009-EIP-46"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":66832,"updated":"2025-01-22T00:52:24.991160+00:00","links":{},"created":"2025-01-18T23:27:28.615927+00:00"}
