High-quality cardiopulmonary resuscitation (CPR) requires stable control of compression rhythm and depth, yet most training systems presuppose instructor mediation, repeated practice, and explanatory guidance-assumptions that do not hold in the Tibet Autonomous Region, where instruction is fragmented and learners' linguistic and educational backgrounds are heterogeneous. We present TibetCPR, a low-cost, self-guided CPR training system that pairs depth-driven electrotactile feedback with rhythm-driven visual cues within a Tibetan-language narrative. In a randomised study with 40 lay community members aged 19--56, the experimental group showed progressive minute-by-minute stabilisation of rhythm and depth across a 10-minute intervention, substantially exceeding an unguided-practice control, with gains transferring to an unscaffolded one-minute post-test. Qualitative accounts described the feedback as legible through participants' bodily action, and usability was high (SUS = 84.3). We synthesise three transferable design principles for self-guided embodied training: feedback as a calibration reference, not an immediate corrector; modality temporal granularity matched to behaviour's temporal structure; and autonomous interpretability as a deployment prerequisite, not an after-effect of usability.

翻译：高质量心肺复苏（CPR）要求稳定控制按压节律与深度，然而现有训练系统普遍预设了教师指导、重复练习及解释性引导等条件——这些预设条件在西藏自治区均不适用，当地教学资源碎片化，学习者的语言与教育背景差异显著。本文提出西藏CPR——一种低成本、自主引导的CPR训练系统，将深度驱动的电触觉反馈与节律驱动的视觉提示相结合，并融入藏语叙事框架。在针对40名19-56岁社区居民的随机对照实验中，实验组在10分钟干预中按压节律与深度呈现逐分钟渐进式稳定，显著超越无指导的对照组，且该增益可迁移至后续1分钟无支架测试。质性反馈表明参与者能通过身体动作解读触觉信号，系统可用性评分高达84.3（SUS量表）。我们提炼出三项可迁移的自主引导具身训练设计原则：将反馈作为校准参照而非即时纠正器；模态时间粒度需匹配行为时间结构；自主可解释性应作为部署前置条件而非可用性的衍生效应。
