Description¶

From trajectory data, qualitative accounts, and usability outcomes, the authors 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." In TibetCPR this is realised as a continuous visual rhythm channel for the continuously-regulated compression rate and a discrete electrotactile depth channel that fires only outside the recommended range, with deterministic rule-based mappings whose semantics are inferable through bodily action alone.

Design Implications¶

Context¶

Requirements¶

• Feedback signals must be interpretable through the user's own bodily action without external mediation, supported by deterministic, rule-based mappings

Constraints¶

• The principles were synthesised from a single formative evaluation in high-altitude, resource-limited Tibetan settings with CPR-naive lay learners

Target Learners¶

• Lay bystanders in self-guided, instructor-limited training contexts

Target Learning Goals¶

• Embodied motor-skill acquisition and stabilisation, such as CPR compression depth and rhythm

Claims¶

• TibetCPR training produced depth-accuracy gains that substantially exceeded unguided practice and transferred to an unscaffolded post-test [+W]
• Depth accuracy rose progressively during the intervention, with the experimental group improving roughly three percentage points per minute faster than the control group [+W]
• In a randomised study with 40 CPR-naive lay adults in Tibet, 10 minutes of TibetCPR training produced rhythm-stabilisation gains that substantially exceeded unguided practice and transferred to an unscaffolded post-test [+W]
