The platform adopts GMM based WLAN location estimation method, and the platform intends to be practical use. Though, there is a cost problem to put the platform to practical use. The estimation method needs observation of WLAN information of the floor at intervals of short distance previously. The platform supposes that general users do the observation work. Therefore, the platform adopts UGC (User Generated Content) approach to share the work in multiple users. If the user does not know the proper interval of observation, the user may observe more than necessary. We conducted experiments in the shopping center to verify the possibility of the practical use of the platform. In the experiments, we figured out that the platform can collect wireless LAN observation information from multiple users. Additionally, we found that the most effective interval between observation points is about 5m.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"3273","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"3263","bibliographicIssueDates":{"bibliographicIssueDate":"2011-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"52"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":79527,"updated":"2025-01-21T20:10:42.393567+00:00","links":{}}
