optical barcodes, such as QR codes, shown on a display may degrade the aesthetics of any underlying visual content as they are not decipherable by humans. To solve this problem, there have been several attempts to embed imperceptible markers with color vibration. However, when users try to read the markers with their camera, the readable range is determined by the physical size of the markers. This paper proposes a method of multiplexing markers of different angular color vibrations in the color space to extend the readable range. Experimental results show that the extension of the readable range can be obtained by the proposed system.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"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":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-05-25","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2021-HCI-193"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":211367,"updated":"2025-01-19T17:49:28.284964+00:00","links":{}}
