Our system obtains the place coordinate such as latitude and longitude by means of the GPS and the direction for forward movement by means of a fluxgate compass. The numerical data are transformed to the place name using the place name layer of the geographic information database. In this paper we experimentally considered availability of both place name and crossroad layers. To this end, sighted participants were blind-folded and walked along a given route (about 1 kilometer) using the system. We clarified particularly a reduction in time using the principal components analysis and the discriminant function. This indicated that one layer alone, the place name layer, was in itself sufficient to walk the route, but using multiple layers, which were classified into different categories, one could walk more efficiently. In our system we developed a multi-layer structure in the geographic information database.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"5028","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tano, Eiichi"}]},{"nameIdentifiers":[{"nameIdentifier":"5029","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Maeda, Yoshinobu"}]},{"nameIdentifiers":[{"nameIdentifier":"5030","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Makino, Hideo"}]},{"nameIdentifiers":[{"nameIdentifier":"5031","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Konishi, Takashi"}]},{"nameIdentifiers":[{"nameIdentifier":"5032","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ishii, Ikuo"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"地理情報システム学会"}]},"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":"AN10457305","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13405381","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田野, 英一"}],"nameIdentifiers":[{"nameIdentifier":"5023","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"前田, 義信"}],"nameIdentifiers":[{"nameIdentifier":"5024","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"牧野, 秀夫"}],"nameIdentifiers":[{"nameIdentifier":"5025","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小西, 孝史"}],"nameIdentifiers":[{"nameIdentifier":"5026","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石井, 郁夫"}],"nameIdentifiers":[{"nameIdentifier":"5027","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":"2019-07-29"}],"displaytype":"detail","filename":"9_2_41-51.pdf","filesize":[{"value":"872.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"9_2_41-51.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/1687/files/9_2_41-51.pdf"},"version_id":"8d30efe8-5e48-437c-8c2a-b0fa961c7db3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"視覚障害者","subitem_subject_scheme":"Other"},{"subitem_subject":"判別関数","subitem_subject_scheme":"Other"},{"subitem_subject":"マハラノビス距離","subitem_subject_scheme":"Other"},{"subitem_subject":"レイヤ","subitem_subject_scheme":"Other"},{"subitem_subject":"Visually impaired people","subitem_subject_scheme":"Other"},{"subitem_subject":"Discriminant function","subitem_subject_scheme":"Other"},{"subitem_subject":"Mahalanobis distance","subitem_subject_scheme":"Other"},{"subitem_subject":"layer","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":"視覚障害者用GPS位置案内システムにおける情報多層化の評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"視覚障害者用GPS位置案内システムにおける情報多層化の評価"},{"subitem_title":"視覚障害者用GPS位置案内システムにおける情報多層化の評価","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-02-27"},"publish_date":"2014-02-27","publish_status":"0","recid":"1687","relation_version_is_last":true,"title":["視覚障害者用GPS位置案内システムにおける情報多層化の評価"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:34:24.787170+00:00"}
