It is important to provide practice-oriented education for nurses in a safe environment. As it became difficult to maintain face-to-face education and practice environment due to COVID-19, a new paradigm for nurse education was required. The investigators tried to use augmented reality technology in nurse education, and based on this, research was conducted to devise, develop, apply, and evaluate the satisfaction and usability of educators. The field needs were checked through literature review, the subject of the augmented technology-based education program was selected, and the program was produced and applied, and this was evaluated through a questionnaire including a system usability evaluation scale and a technology acceptance model-based question.

As patient-centered nursing education is considered more important, the amount of nursing education required is also increasing. In addition, the safety of the educational environment is important for nurses' application education to various clinical environments. In the past, simulation education, which generally expects learning effects through practice and motivation, was mainly conducted. However, in the COVID-19 situation, it has become difficult for educators and educators to gather in one space to conduct clinical education.[4] Based on the need for alternatives to this, The investigators devised a nurse education program using various new technologies.

Recently, virtual training systems are being developed in various application fields thanks to the development of augmented reality and virtual reality. In particular, medical training and clinical application have become important since the recent international epidemic of COVID-19. The strength of new technologies such as Augmented Reality (AR) has enabled various programs for education and healthcare that have overcome the limitations of time and space. Augmented reality is already being applied to self-directed learning in various areas, which provides learners with a highly immersive learning environment so that medical personnel can receive more accurate and precise medical education in the field.

The investigators tried to develop an augmented reality technology-based program that can provide training to nurses using the Headmount display device, and to find out the evaluation that reaches usability and satisfaction after applying it to educators.
