1. A training system comprising:
a first tracker mounted to a physical model of a head and neck, the physical model of the head and neck comprising hard plastic components and soft plastic components mounted to the hard-plastic components, the hard-plastic components including physical models of skull, teeth, larynx, tracheal cartilage and jaw, the soft components including physical models of tongue, epiglottis, pharynx lining, and esophagus;
a second tracker mounted to a physical model of a laryngoscope;
a third tracker mounted to a physical model of an endotracheal tube;
a display device;
a tracking and mechanical sensing system configured to track a location, an orientation, velocity and acceleration of the first, second, and third tracker and to determine relative positions of the model of the laryngoscope, the physical model of the endotracheal tube, and the physical model of the head and neck; and
a simulation system coupled to the tracking and mechanical sensing system, the simulation system comprising at least one processor and a memory, the memory comprising digital three-dimensional (3D) models of a laryngoscope, an endotracheal tube, and an airway, the airway further comprising 3D models of surfaces of tongue, epiglottis, larynx, pharynx, and trachea;
where the digital 3D models of surfaces of tongue, epiglottis, larynx, pharynx, and trachea corresponding to the physical models of tongue, epiglottis, pharynx lining, and trachea.
