TibetCPR: A Multimodal Tactile Feedback System to Enhance Cardiopulmonary Resuscitation Training in High-Altitude Regions of Tibet

2026-06-05

AI Summary

This study addresses the challenges of CPR training in high-altitude regions, where limited instructor availability and linguistic-cultural diversity among learners hinder the scalability of traditional, instructor-dependent methods. To overcome these barriers, the authors propose a low-cost, self-guided CPR training system that integrates depth-driven electrotactile feedback, rhythm-synchronized visual cues, and a Tibetan-language narrative interface. The design is grounded in three transferable embodied training principles: using feedback as a calibration reference rather than for immediate correction, aligning multimodal temporal granularities with behavioral structure, and embedding system explainability prior to deployment. Experimental results demonstrate that trainees achieved significantly more stable compression depth and rhythm within ten minutes, with performance gains persisting into unassisted testing. The system exhibited high usability (SUS = 84.3), and participants consistently reported clear and intuitive operation.

Abstract

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.
