This system is intended for analysis of R-R interval fluctuation which is related to drowsiness and stress. Our goal is to detect changes in R-R interval fluctuation and alert the driver to prevent drowsy driving. ECG was measured with a contact electrode on the steering wheel and a capacitive coupling electrode on the driver’s seat. Baseline fluctuation can be as large as hundred times of the R-wave. In order to utilize differential amplification to reduce the fluctuation, an additional seat electrode was placed on top of the seat electrode with a paper insulator in between the two electrodes. Baseline fluctuation was reduced by taking the difference between the two signals. The proposed measurement method was evaluated in a real car","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8974","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tomimori, Hideki"}]}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"master"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"新領域創成科学研究科人間環境学専攻"}]},"item_7_text_27":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_value":"修創域第3057号"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院新領域創成科学研究科環境学研究系人間環境学専攻"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"冨森, 英樹"}],"nameIdentifiers":[{"nameIdentifier":"8973","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-31"}],"displaytype":"detail","filename":"K-01770-a.pdf","filesize":[{"value":"199.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨(summary)","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/3841/files/K-01770-a.pdf"},"version_id":"7b40d225-9982-448b-9900-15ea1377395b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Drowsy driving","subitem_subject_scheme":"Other"},{"subitem_subject":"ECG","subitem_subject_scheme":"Other"},{"subitem_subject":"R-R interval","subitem_subject_scheme":"Other"},{"subitem_subject":"Capacitive coupling","subitem_subject_scheme":"Other"},{"subitem_subject":"Signal processing","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"自動車運転中の心拍周期計測の信号処理に関する研究（要旨）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自動車運転中の心拍周期計測の信号処理に関する研究（要旨）"}]},"item_type_id":"7","owner":"1","path":["234","256"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-12"},"publish_date":"2012-10-12","publish_status":"0","recid":"3841","relation_version_is_last":true,"title":["自動車運転中の心拍周期計測の信号処理に関する研究（要旨）"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:45:33.071439+00:00"}
