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\u2019s 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": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "8974", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Tomimori, Hideki"}]}]}, "item_7_select_21": {"attribute_name": "\u5b66\u4f4d", "attribute_value_mlt": [{"subitem_select_item": "master"}]}, "item_7_text_24": {"attribute_name": "\u7814\u7a76\u79d1\u30fb\u5c02\u653b", "attribute_value_mlt": [{"subitem_text_value": "\u65b0\u9818\u57df\u5275\u6210\u79d1\u5b66\u7814\u7a76\u79d1\u4eba\u9593\u74b0\u5883\u5b66\u5c02\u653b"}]}, "item_7_text_27": {"attribute_name": "\u5b66\u4f4d\u8a18\u756a\u53f7", "attribute_value_mlt": [{"subitem_text_value": "\u4fee\u5275\u57df\u7b2c3057\u53f7"}]}, "item_7_text_36": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Thesis"}]}, "item_7_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u6771\u4eac\u5927\u5b66\u5927\u5b66\u9662\u65b0\u9818\u57df\u5275\u6210\u79d1\u5b66\u7814\u7a76\u79d1\u74b0\u5883\u5b66\u7814\u7a76\u7cfb\u4eba\u9593\u74b0\u5883\u5b66\u5c02\u653b"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u51a8\u68ee, \u82f1\u6a39"}], "nameIdentifiers": [{"nameIdentifier": "8973", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-05-31"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "K-01770-a.pdf", "filesize": [{"value": "199.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 199800.0, "url": {"label": "\u8981\u65e8(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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "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": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "\u81ea\u52d5\u8eca\u904b\u8ee2\u4e2d\u306e\u5fc3\u62cd\u5468\u671f\u8a08\u6e2c\u306e\u4fe1\u53f7\u51e6\u7406\u306b\u95a2\u3059\u308b\u7814\u7a76\uff08\u8981\u65e8\uff09", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u81ea\u52d5\u8eca\u904b\u8ee2\u4e2d\u306e\u5fc3\u62cd\u5468\u671f\u8a08\u6e2c\u306e\u4fe1\u53f7\u51e6\u7406\u306b\u95a2\u3059\u308b\u7814\u7a76\uff08\u8981\u65e8\uff09"}]}, "item_type_id": "7", "owner": "1", "path": ["9/233/234", "110/255/256"], "permalink_uri": "http://hdl.handle.net/2261/37082", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2012-10-12"}, "publish_date": "2012-10-12", "publish_status": "0", "recid": "3841", "relation": {}, "relation_version_is_last": true, "title": ["\u81ea\u52d5\u8eca\u904b\u8ee2\u4e2d\u306e\u5fc3\u62cd\u5468\u671f\u8a08\u6e2c\u306e\u4fe1\u53f7\u51e6\u7406\u306b\u95a2\u3059\u308b\u7814\u7a76\uff08\u8981\u65e8\uff09"], "weko_shared_id": null}
