In　the　Plan　for　New-generation　Artificial　Intelligence　Development　promulgated　by　the　state　in　recent　years,　the　introduction　of　artificial　intelligence　and　immersive　teaching　into　smart　education　has　been　put　forward,　aiming　to　construct　the　online　education　model　with　an　XR　integration　and　to　build　interactive　learning　environment　through　the　energizing　of　5G.　This　project　discusses　about　how　to　design　education　products　integrating　virtual　and　real　factors　so　as　to　effectively　improve　the　situationality　and　experience　of　children　in　the　learning　of　music　theory,　mobilize　children　to　learn　through　visual　sense,　kinesthesis,　hearing　and　other　senses　with　the　help　of　AR　recognition　technology,　thus　presenting　abstract　concepts　and　theories　to　the　children　in　a　more　intuitive　way,　thus　improving　their　learning　efficiency.　Finally,　the　researchers　designed　and　developed　a　set　of　game　products　for　music　learning　combining　software　and　hardware,　and　a　usability　test　of　the　prototype　was　conducted　so　as　to　carry　out　the　iterated　design.　The　design　in　this　project　addresses　the　problems　of　boredom　and　passive　learning　seen　in　children　learning　music　theory　in　the　traditional　way,　combines　obscure　knowledge　of　music　theory　with　interactive　games,　thus　promoting　children　learners’　understanding　of　music　theory.　The　way　of　immersive　learning　with　an　integration　of　virtual　and　real　factors,　interactive　means　and　perception　methods　have　improved　the　learning　efficiency　and　creativity　of　the　learners,　optimized　the　design　and　realization　process　of　the　interaction　and　feedback　mechanism,　and　brought　about　game-changing　changes　to　educational　ideas　and　teaching　approaches.　©　2021,　Springer　Nature　Switzerland　AG.
