And the opportunity to get a variety of information using the mobile devices through the two-dimensional code has been increasing, but the transmission means of the information is limited to the images, so it is difficult to be used for visually-impaired persons. And when using audio data in a network environment, the burden of visually-impaired persons is increased. Even though the voice data of two-dimensional code can be stored in some system, it is difficult to ensure sufficient data capacity and realize visualization data of two-dimensional code. In this paper, according to multi-valued two-dimensional code by an encoding method, we propose an approach to embed sufficient new data and simultaneously it is available by a conventional decoder. By embedding the audio data of the two-dimensional code by using the proposed method, healthy people can use the two-dimensional code as usual, visually impaired persons can use the audio data. A support system for visually-impaired persons is constructed. In addition, the proposed method has an engineering versatility, such as embed music data and confidential information, because it is not restricted to the use of a conventional decoder.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2768","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2757","bibliographicIssueDates":{"bibliographicIssueDate":"2016-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"57"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:46:05.187430+00:00","id":176439,"links":{}}
