In previous works a user is equipped with tactile device to present tactile stimuli on the place where virtual objects touch him. However, the area in which the system can provide him with tactile stimuli depends on the place where is covered by the tactile devices. Thus, it has been difficult to give him tactile stimuli in an arbitrary place. Our aim is to establish a representation method of tactile stimuli independent of locations of the devices. In this paper to control locations of tactile stimuli by tactile illusion caused by visual stimuli, we have investigated the correlation between visual stimuli and tactile perception. Based on the subjective experiments, we observe that subjects feel the perceived positions of vibrotactile sensation shifted to those of visual sensation, and the influence of visual stimuli is changed by the movements of visual objects. On the other hand, to achieve higher presentation to the upper limb we have investigated the difference of the forearm and the palm in vibrotactile perception, and we have examined the tactile display method in each palce.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8155","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Niijima, Arinobu"}]}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"master"}]},"item_7_subject_13":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"548","subitem_subject_scheme":"NDC"}]},"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":"新島, 有信"}],"nameIdentifiers":[{"nameIdentifier":"8154","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":"37106483.pdf","filesize":[{"value":"4.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"37106483.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/3390/files/37106483.pdf"},"version_id":"1ece8294-08bf-40df-a8f0-3ba435f2d744"}]},"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視覚刺激を利用した上肢への触覚提示手法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"拡張現実感における視覚刺激を利用した上肢への触覚提示手法"}]},"item_type_id":"7","owner":"1","path":["234","271"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-18"},"publish_date":"2012-05-18","publish_status":"0","recid":"3390","relation_version_is_last":true,"title":["拡張現実感における視覚刺激を利用した上肢への触覚提示手法"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:45:02.044052+00:00"}
