Extended Reality in early childhood education presents high-risk challenges due to children's rapid developmental changes. While augmented and virtual reality offer immersive pedagogical benefits, they often impose excessive cognitive load or sensory conflict. We introduce the Augmented Human Development (AHD) framework to model these interactions through cognitive, sensory, environmental, and developmental parameters. To ground this framework, we conducted a Systematization of Knowledge (SoK) of 111 peer-reviewed studies involving children aged 3 - 8. Our findings, interpreted through the AHD lens, reveal a critical "risk vs. attention gap," where high-impact safety and security risks remain under-researched compared to short-term pedagogical gains.

翻译：扩展现实在幼儿教育中因儿童快速发育变化而存在高风险挑战。虽然增强现实和虚拟现实能提供沉浸式教学优势，但它们常带来过高的认知负荷或感官冲突。我们提出增强人类发展框架，通过认知、感官、环境和发育参数对这些交互进行建模。为夯实该框架，我们对111项涉及3-8岁儿童的同行评审研究进行了知识系统化分析。通过AHD视角解读的研究结果揭示了一个关键的“风险与关注度差距”：相较于短期教学收益，高影响度的安全与安保风险仍未得到充分研究。
