paper, we describe a novel high-accuracy 3-D positioning method for a smartphone using direct and reflected acoustic signals from two existing installed speakers. We propose a new concept called Mirror image speaker regarding primary reflected signals from a wall and a floor as signals transmitted from a virtual speaker at a mirror image position of its original one. We hold a smartphone horizontally, and specify a real speaker and mirror image speakers by using two microphones built-in a smartphone. In our experiments, we installed speakers at intervals of 2.5m along a corridor and estimated the smartphone position at several places on a reflective and an absorptive floor. From these results, we obtained 90th-percentile errors of less than 37.7mm and maximum random errors of less than 5.22mm for 3-D positioning. Furthermore, we clarified the usefulness of mirror image speakers using Dilution of Precision (DoP) measures and confirmed it through computer simulations.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2324","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2314","bibliographicIssueDates":{"bibliographicIssueDate":"2019-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"60"}]},"relation_version_is_last":true,"weko_creator_id":"33195"},"created":"2025-01-19T01:04:48.152881+00:00","id":201542,"links":{}}
