The MR BLS Rescue Trainer is a training system that allows users to experience realistic simulation with physical feeling in lifesaving procedures, that is BLS (basic-life-support), including CPR (cardiopulmonary-resuscitation) and AED (Automated External Defibrillator) by applying physical mixed reality incorporated with partially tangible components. The system consists of an HMD, a human chest model for CPR training, an AED simulator, and a PC. The human model and the AED simulator are integrated with a microcontroller and connected to the PC. The human model is placed on the floor. And then the user wears the HMD, kneels on the floor, and performs life-saving actions according to the detailed instructions displayed on the HMD.
