This demo integrates our advanced Tactical Combat Casualty Care (TC3) mixed reality (MR) platform initially developed for U.S. Army medics with Inhance’s virtual safety and logistic platform (VSLP) technology to revolutionize training for EMTs and first responders. By overlaying critical emergency medicine life-saving procedures on physical manikins, the system provides an immersive, real-world simulation that enhances procedural training and decision-making in high-stress scenarios and increases learning velocity and retention. Users put on an MR headset to see anatomically accurate 3D holographic overlays onto a standard training manikin, simulating realistic trauma scenarios and guiding trainees through life-saving interventions.
