Augmented reality (AR) technology assists construction workers by superimposing additional virtual information onto their real worksite environments. Ideally, this provides them with a better understanding of their tasks and hence boosts task performance. However, the additional information that AR places in users' field of view could limit their ability to understand what is going on in their surroundings and to predict how conditions may change in the near future. AR-assisted systems on construction sites could therefore expose their users to safety risks due to disturbance from the system. Hence, it is important to understand how AR-assisted systems can block users' understanding of their immediate environments, and in turn, how worksite safety in the construction industry could be improved through better design of such systems. This preliminary research conducted a laboratory experiment that simulated rebar inspection tasks and compared the situational awareness of AR users against that of subjects using traditional paper-based inspection methods, as measured by the Situation Awareness Rating Technique. Based on the results, we discuss the safety impact of head-mounted AR-assisted displays on situational awareness during construction tasks.

이 연구는 급성관상동맥증후군을 경험한 환자의 상황인식 수준 측정을 위한 SART 도구의 신뢰도와 타당도를 검증하기 위해 시도되었다. 입원한 급성관상동맥증후군 환자 118명에게 번역된 SART 도구를 적용하여 도구의 신뢰도와 타당도를 분석하였다. 도구의 신뢰도와 타당도는 Cronbach 알파, 탐색적, 확인적 요인분석을 통해 분석하였다. 연구 결과 상황 인식 1(Instability of Situation, 상황의 불안정성)과 상황 인식 7(Spare Mental Capacity, 여분의 정신력)의 두 문항을 제거하였을 때 도구의 신뢰도와 모델 적합도 지수가 향상되는 것으로 나타났다. 수정된 국문판 SART는 급성관상동맥증후군 환자의 치료추구행동에 대한 의사결정 시 상황인식 정도를 측정하는 데 적절한 도구로 판단된다.
