SA/SNZ TR ISO/IEC 23842.1:2021同样采用ISO/IEC TR 23842 1:2020，该标准提出了在学习、教育和培训（LET）领域使用虚拟现实内容的注意事项，以减少用户之间的现实和虚拟现实交叉混淆，并帮助用户有效地使用这些技术。它涵盖了在LET域中使用头戴式显示器（HMD）的VR内容，不涵盖使用沉浸式技术的VR内容，也不涉及增强现实、混合或合并现实内容。

SA/SNZ TR ISO/IEC 23842.1:2021 identically adopts ISO/IEC TR 23842 1:2020, which presents considerations for using VR content in learning, education and training (LET) domain for reducing reality and virtual reality crossover confusion among users and assisting users to effectively use these technologies. It covers VR content that uses a head-mounted display (HMD) in the LET domain and does not cover VR content using immersive technology and does not address augmented reality, mixed or merged reality content.
