In this system the persistency of virtual reality objects is realized. The block-world database system allows for a user to enter the block-world database so that he/she can see blocks by their own eyes, and by attaching a data glove on a hand he/she can touch, grasp, move, release a block as well as compose two locks. A gesture language is designed and implemented for that purpose. In order to represent the real world as faithful as we can, an interference check algorithm among blocks and a free-falling algorithm of a block are implemented. In other words the block-world database system is a life-size database management system.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"104","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"91","bibliographicIssueDates":{"bibliographicIssueDate":"1999-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG03(TOD1)","bibliographicVolumeNumber":"40"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"updated":"2025-01-22T23:08:07.713536+00:00","created":"2025-01-18T22:50:42.178924+00:00","id":17798}
