Head Mounted Display (HMD) を装着した VR ユーザを認証する方式として，指の動作を活用したハンドジェスチャ認証方式を開発する．VR ユーザが自然に行うハンドジェスチャとして，2 本の指を用いたピンチ動作を採用する．提案方式の狙いは，既存のパターンロックやパスコードを用いた VR ユーザの認証方式と比較して，高いユーザビリティを達成することである．提案する VR ユーザ認証方式を Meta Quest 2 上で動作するシステムとして実装し，18 人のユーザでユーザスタディを行った．この結果，非リアルタイム認証では，平均正解率が 0.979 と高い精度になった．一方で，リアルタイム認証では平均正解率が 0.847 となり，さらなる精度向上が課題となった．システムのユーザビリティを評価する SUS スコアは全体平均が 79.1 となり，B ランクに相当する比較的高いユーザビリティを達成した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-03-06","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2023-SPT-50"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
