Due to the recent outbreak of Corona 19 (COVID-19) around the world, many confirmed cases and casualties are occurring. Corona 19 is a respiratory infectious disease, mainly spread by droplets of an infected person penetrating the respiratory tract or the mucous membranes of the eyes, nose and mouth. In other words, Corona 19 is spread by coughing or sneezing, or by touching a material contaminated with the virus and then touching your eyes, nose, and mouth with your hands.

Accordingly, educational institutions such as universities are conducting classes in a non-face-to-face manner to prevent the spread of COVID-19, but problems such as equity in attendance and exams, low learning satisfaction, and cheating are occurring.

On the other hand, CPX (Clinical Performance Examination) measures comprehensive clinical performance in an environment similar to the actual clinical situation, and provides various It is intended to evaluate trainees in terms of aspects, and it means the most comprehensive test form currently used by almost all medical schools in the United States since the concept of standardized patients was first announced in 1963.

This CPX consists of items of interview, physical examination, and interview. Among them, although the physical examination item has to learn many cases through hands-on training, it is equally distributed to trainees according to time and space constraints in the field. There are problems in that it is impossible to provide a practical opportunity, and the effectiveness of education is lowered because the practice cannot be repeatedly performed.

It is an object of the present invention to solve the above-mentioned conventional problems, and to provide a practical education system using VR for performing physical examination practical education of CPX using VR.
