We specified the time-frequency representation (TFR) of image motion vectors that would affect the autonomic nervous activity under vection-induced images. Referring to the trigger points of cybersickness determined by autonomic nervous activity related indices, we found that the TFR contains both the lower frequency components under 3 Hz with several seconds and the higher frequency components with several hundreds milliseconds. Moreover, the similarity between different image motion vectors, which characterizes the TFR by cos29 between different vectors, changed similarly as the distribution of trigger points of cybersickness in time.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "43998", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kiryu, Tohru"}]}, {"nameIdentifiers": [{"nameIdentifier": "43999", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Nambo, Yoko"}]}, {"nameIdentifiers": [{"nameIdentifier": "44000", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Nomura, Eri"}]}, {"nameIdentifiers": [{"nameIdentifier": "44001", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Bando, Takehiko"}]}, {"nameIdentifiers": [{"nameIdentifier": "44002", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kobayashi, Naoki"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本バーチャルリアリティ学会"}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "本文データはCiNiiから複製したものである"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11448578", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1344011X", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "木竜, 徹"}], "nameIdentifiers": [{"nameIdentifier": "43993", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "南保, 洋子"}], "nameIdentifiers": [{"nameIdentifier": "43994", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "野村, 恵里"}], "nameIdentifiers": [{"nameIdentifier": "43995", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "板東, 武彦"}], "nameIdentifiers": [{"nameIdentifier": "43996", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "小林, 直樹"}], "nameIdentifiers": [{"nameIdentifier": "43997", "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": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "110008746953.pdf", "filesize": [{"value": "1.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1000000.0, "url": {"label": "110008746953.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3608/files/110008746953.pdf"}, "version_id": "27d08ea2-44ca-4111-b68f-3ba6620d85ef"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "cybersickness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "vection-induced images", "subitem_subject_scheme": "Other"}, {"subitem_subject": "motion vector", "subitem_subject_scheme": "Other"}, {"subitem_subject": "autonomic nervous activity", "subitem_subject_scheme": "Other"}, {"subitem_subject": "time-frequency representation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "similarity", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "自己運動感を伴う映像の動きベクトルによる生体影響評価法(\u003c特集\u003eサイバー空間の安全・健康・快適性)", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "自己運動感を伴う映像の動きベクトルによる生体影響評価法(\u003c特集\u003eサイバー空間の安全・健康・快適性)"}, {"subitem_title": "自己運動感を伴う映像の動きベクトルによる生体影響評価法(\u003c特集\u003eサイバー空間の安全・健康・快適性)", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "470"], "permalink_uri": "http://hdl.handle.net/10191/20262", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-10-25"}, "publish_date": "2012-10-25", "publish_status": "0", "recid": "3608", "relation": {}, "relation_version_is_last": true, "title": ["自己運動感を伴う映像の動きベクトルによる生体影響評価法(\u003c特集\u003eサイバー空間の安全・健康・快適性)"], "weko_shared_id": null}
