Moreover, the demand for the collaboration by sharing the virtual environment in a field of data visualization has been rising. In this paper, we developed an audio library for voice communication (vocAL) to realize smoothy communication in a collaborative virtual environment over the wide area network (WAN). The vocAL can dynamically adjust the sound volume and the PAN level correspond to the position of a speaker in VR environment. To realize a voice communication in multipoints without a MCU and IP multicast, we constructed a HybridP2P network and proposed a method which assigned different port number for each communication path. In this experiment via campus LAN, we showed high-quality voice communication, while a problem of delay generated.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"20","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告ヒューマンコンピュータインタラクション（HCI）"}],"bibliographicPageStart":"15","bibliographicIssueDates":{"bibliographicIssueDate":"2004-07-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"74(2004-HI-109)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:04:49.053978+00:00","id":36818,"links":{}}
