In previous works, a user have to equip or grasp a haptic device simulating haptic feedback from virtual objects. However, equipping or grasping a device prevent a user from moving naturally. Our aim is to realize haptic feedback without a haptic device in augmented reality using pseudo-haptics which is a phenomenon where visuo-haptic sensory conflicts. In this paper, we investigated the occurrence of pseudo-haptics in augmented reality and the condition where we simulate haptic feedback efficiently using pseudo-haptics. Based on subjective experiments, we observed pseudo-haptics occurs in augmented reality and an influence to haptic sense differs depending on a displayed hand speed.","subitem_description_type":"Abstract"}]},"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":"工学系研究科・電気系工学専攻"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院工学系研究科電気系工学専攻"},{"subitem_text_value":"Department of Electrical Engineering and Information Systems, Graduate School of Engineering, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大塚, 隆史"}],"nameIdentifiers":[{"nameIdentifier":"10576","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":"2017-06-01"}],"displaytype":"detail","filename":"37116430.pdf","filesize":[{"value":"5.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"37116430.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/4872/files/37116430.pdf"},"version_id":"52b4a696-2547-4db5-a52d-8333d4f30779"}]},"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":"拡張現実感における擬似触覚を用いた力覚フィードバック提示手法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"拡張現実感における擬似触覚を用いた力覚フィードバック提示手法"}]},"item_type_id":"7","owner":"1","path":["234","271"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-07"},"publish_date":"2013-05-07","publish_status":"0","recid":"4872","relation_version_is_last":true,"title":["拡張現実感における擬似触覚を用いた力覚フィードバック提示手法"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:46:32.279001+00:00"}
