における周波数特性を，T0℃ における周波数特性に対して，周波数方向と振幅方向に補正する．この補正を用い，サーフェス上に置かれた物体の種類（3種類）と位置（3カ所）を異なる環境温度（17種類，22.7℃～30.5℃）下で識別するテストを実施した結果，物体の平均識別率が補正なしの21.5%から75.1%に向上することを確認した．","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"We have previously proposed SenseSurface, a plate-like system that recognizes object type and location using active acoustic sensing, for the purpose of achieving a more accurate and unconscious context awareness. SenseSurface recognizes objects by applying a sweep signal whose frequency changes with time to a surface and analyzing the change in the acoustic frequency response given to the sweep signal from the response. However, there remain a problem with active acoustic sensing that the acoustic frequency characteristics of the surface vary with the environmental temperature, which reduces the recognition performance of SenseSurface. This paper investigates the effect of environmental temperature on the acoustic frequency response and try to compensate for the influence of the environmental temperature based on the findings. Specifically, the change in the acoustic frequency response at T1℃ is corrected in the frequency and amplitude directions against the change in the acoustic frequency response at T0℃. Using this correction method, we tested the discrimination of multiple object types (three types) and locations (three locations) placed on the surface under different environmental temperatures (17 patterns ranging from 22.7℃ to 30.5℃), and confirmed that the average object discrimination rate improved from 21.5% to 75.1%.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1668","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1658","bibliographicIssueDates":{"bibliographicIssueDate":"2021-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"62"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00213193","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"updated":"2025-01-19T17:10:06.876617+00:00","created":"2025-01-19T01:14:11.102487+00:00","links":{}}
