증강현실 디바이스에 따른 체험자 안전확보 방안의 유형 및 특성 연구

Abstract

(Background and Purpose) Augmented reality (AR) technology is easily accessible through various devices such as smartphones and AR glasses, and is used in various industries. However, collisions between pedestrians are constantly occurring when using AR content, and there have been cases where even fatal accidents have occurred overseas because user safety has not been secured. Therefore, the purpose of this study is to identify problems by analyzing an experiential environment in which AR is currently being used, and to suggest ways to secure safety in AR environment. (Method) In the research method, it analyzes the characteristics and technical parts of AR devices to classify the device types and analysis elements. Considering the characteristics and experiences of each type of device, it analyzes the experiential AR environment centered on representative cases after confirming the theoretical background for safety measures. (Results) This study classified AR devices into three types. In the case of a mobile device type, it was confirmed that there are limitations in terms of body utilization and gazing point. In response to it, a pop-up safety phrase and a warning message in the UI were suggested as a way to secure safety. In the case of a wearable device type, it confirmed the limits of the viewing angle and spatial awareness. In response to it, a vibration notification function, and safety personnel and docent personnel were suggested to be added. In the case of a projection type, it was found that a problem occurs in the collision part between a person and a person or between a person and a structure. In response to it, it was recommended to provide a detailed guide on the recommended distance between users, and the material and location information of the installation structure in advance. (Conclusions) It can be confirmed that the user safety measure is insufficient in the current experiential environment using AR. Regarding it, the author presented a guide on how to secure safety according to the AR device type. First, the mobile device type is hoped to be used for a more pleasant experience of AR tourism in the tourism industry. Second, the wearable device type is hoped to be used for more efficient on-the-job AR training in the field of industrial job education. Third, the projection type is hoped to be used in the entertainment industry for more systematic operation of experience halls and AR zones in an exhibition hall. Above all, it is hoped that it will contribute to securing the safety of AR users across all industries. It is hoped that this study will be used as useful data for the development of AR safety measures in the future.
