Moreover, students often give &ldquo;proxies,&rdquo; also called as <i>Daihen</i> in Japanese, during lectures. The prevention of <i>Daihen</i> will increase attendance and therefore improvement the efficacy of education. The purpose of this study is to develop a short and difficult <i>Daihen</i> attendance confirmation system. We have developed an attendance confirmation system called AGENGO using hard-to-verbalize images. AGENGO is a system that confirms the attendance by selecting images using students' cellular phones. In this paper, we present an evaluation of hard-to-verbalize images and a trial of the system in actual lectures. From the results of the experiments and trials during actual lectures, we concluded the following. ( 1 ) The type of image influences the explanation of the image. The number of similar images does not influence the explanation of the image. ( 2 ) AGENGO required approximately 4窶骭€5 min for attendance confirmation. ( 3 ) It is necessary to handle uncontrollable situations such as mobile phone breakdown, fluctuations in radio waves due to carriers, cellular phone models, and classrooms. ( 4 ) Even when we used hard-to-verbalize images, we found cases where students engaged in the practice of <i>Daihen</i>, as revealed by the AGENGO logs. ( 5 ) When we used very-hard-to-verbalize images, many students were not able to distinguish between a valid image and false images.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2730","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2722","bibliographicIssueDates":{"bibliographicIssueDate":"2008-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"49"}]},"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":"社会・人間系における情報システム"}]},"weko_creator_id":"1"},"id":9528,"updated":"2025-01-23T03:23:26.718398+00:00","links":{},"created":"2025-01-18T22:44:43.268478+00:00"}
