Tube insertion through trachea is a procedure performed by nurses to suck the sputum out of the patient’s trachea. If the procedure is not performed carefully, it causes inconvenience and damages patient’s trachea. To train novice nurses to practice the procedure in a safer environment, we developed a projection mapping-based nurse training simulator, and its effectiveness was evaluated. From the evaluations, it was found that more facial expressions, including choking, coughing, and patient’s relaxed states, still must be integrated into the patient model so the nurse could be more immersed into the simulator. To achieve that, a Facial Action Coding System (FACS)-based video analysis tool is first used to identify the activated facial action units (AU) in those states and they are applied to the synthetic deformations on a 3D face of the patient model. The degree of naturalness, reality and effectiveness are evaluated.
