Due to their evolution to multi-functionality, however, the devices have begun to be used by multiple people in co-located situations. This paper discusses techniques to allow multiple people to share mobile devices by projecting their displays and to conduct intuitive manipulations on them. It is possible to project a display of a mobile device in any location and size, when a mobile device that mounts a projector is available. In today’s technologies, however, it is difficult to realize a mobile device with a small and lightweight projector that still retains the feature of mobility. Therefore, we have developed a system to project displays of mobile devices on a table, in order to track their three-dimensional positions and orientations by using a stereo camera and an existing LCD projector, both of which are installed onto a ceiling. The proposed system called Hotaru (a firefly, in English) allows users to annotate/rotate a picture or a document on a projected display by using their fingers. Users can intuitively transfer a file between multiple devices by making their projected displays overlapped. Evaluations of Hotaru indicated that the proposed manipulation techniques could support multiple people in co-located situations in conducting their tasks.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1985","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1976","bibliographicIssueDates":{"bibliographicIssueDate":"2006-06-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"47"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"ユーザインタフェースとインタラクティブシステム"}]},"weko_creator_id":"1"},"id":10284,"links":{}}
