Based on the questionnaire survey method and the SWOT analysis method, the advantages and disadvantages of the application of AR technology in nursing training are analyzed, and the possible application scenarios of AR technology in nursing training teaching and countermeasures to meet the challenges are proposed. CAI application research has been carried out in the teaching of nursing procedures, and the interactive "nursing medical record writing training system" CAI courseware has been developed. The courseware is composed of 9 functional modules. It has the advantages of convenient use, good interactivity, strong test performance, and flexible expansion. It allows students to collect nursing information, make diagnoses, and make nursing plans through man-machine dialogue. It solves the difficult teaching problems that are difficult to solve by traditional teaching methods.
