A Basic Estimation between Trajectories and Progress of Medical Practice for Medical Education Simulation System in Emergency Medical Services

Emergency medical care involves a high level of urgency and requires a team approach. Thus, the need for simulation-based education is high. Evaluation, however, is difficult to perform. Therefore, we carried out a study to analyze the trajectories of medical personnel during treatment to contribute to simulation-based medical education. We installed four stereo cameras on the ceiling around one treatment bed in an emergency room (ER). We extracted the trajectories of medical personnel and recorded their conversations and the ambient sounds during treatment. In this paper, to investigate the meaning of trajectories in the ER, we analyzed the relationship between the trajectories and the progress of medical activities. Our results showed a clear correlation of the progress of the medical activities with the trajectory distance and the number of starts of movement.
