Safety training is crucial to mitigate the risk of damage when a disaster occurs and can play a vital role in enhancing community response. Augmented Reality (AR) is an emerging technology for safety training that holds great pedagogical potential. This study aims to explore the effectiveness of AR training in terms of knowledge acquisition and retention, as well as self-efficacy enhancement. We developed a new video see-through AR training tool on a tablet to teach users about operating a fire extinguisher to put out a fire following the PASS procedure: Pull, Aim, Squeeze, and Sweep (PASS). The AR training tool was tested with 60 participants. Test results were systematically compared with findings from the literature investigating Virtual Reality (VR) and video-based safety training. The findings indicate that, directly after the training, AR outperformed traditional video training in terms of knowledge retention, long-term self-efficacy, and quality of instructions. However, the AR experience was not as effective as the VR experience in all these areas, but the AR group had a smaller decrease in knowledge over time. These findings suggest that the AR-based training approach offers benefits in long-term memory recall.
Augmented reality applications in construction productivity: A systematic literature review
(Elsevier Ltd, 2024-10) Xu Z; Feng Z; Babaeian Jelodar M; Guo BHW
Augmented reality (AR) has been extensively researched for its applications in the construction industry. However, there is limited focus on its effects on productivity. This paper aims to bridge the gap by using a systematic literature review to investigate AR applications in the planning, design, and construction phases, focusing on their mechanisms for enhancing productivity. The paper classifies AR applications by their target construction tasks, features, and factors contributing to improved productivity. Additionally, it proposes a framework for prototyping AR applications and evaluating their effects on productivity. Key findings reveal several contributions: the need for further investigation of AR for positioning and hazard notification tasks; the utilisation of different augmentation methods, display tools, and tracking methods based on specific construction tasks; AR's positive impact on productivity in design review, discrepancy check, assembly, and hazard notification, while future research on evaluating productivity in progress management, planning simulation, and positioning.
State-of-the-art analysis of the integration of augmented reality with construction technologies to improve construction safety
(Emerald Publishing, 16/11/2022) Khorrami Shad, H.; Tak Wing Yiu, K.; Lovreglio, Ruggiero; Feng, Zhenan
Purpose – This paper aims to explore Augmented Reality (AR) applications in construction safety academic literature and propose possible improvements for future scholarly works. The paper explicitly focuses on AR integration with Construction 4.0 technologies as an effective solution to safety concerns in the construction industry. Design/methodology/approach – This study applied a systematic review approach. Three hundred and eighty-seven potentially relevant articles from databases were identified. Once filtering criteria were applied, 29 eligible papers where selected. The inclusion criteria were being directly associated with construction safety, focused on an AR application, and AR interactions associated with the Construction 4.0 technologies. Findings – This study investigated the structure of AR applications in construction safety. To this end, we studied the safety purposes of AR applications in construction safety: pre-event (intelligent operation, training, safety inspection, hazard alerting), during-event (pinpointing hazard), and post-event (safety estimation) applications. Then, the integration of AR with Construction 4.0 technologies was elaborated. The systematic review also revealed that the AR integration has contributed to developing several technical aspects of AR technology: display, tracking, and human-computer interaction. The study results indicate that AR integration with construction is effective in mitigating safety concerns; however, further research studies are required to support this statement. Originality/value – This study contributes to exploring applications and integrations of AR into construction safety in order to facilitate the leverage of this technology. This review can help encourage practitioners and researchers to conduct further academic investigations into AR application in construction safety.
Augmented reality for pedestrian evacuation research: Promises and limitations
(Elsevier Ltd, 2020-08) Lovreglio R; Kinateder M
Evacuation effectively mitigates potential harm for building occupants in case of emergencies. Virtual and Augmented Reality (VR and AR) have emerged as research tools and means to enhance evacuation preparedness and effectiveness. Unlike VR, where users are immersed in computer-generated environments, the more novel AR technology allows users to experience digital content merged into the real world. Here, we review current (2020) relevant literature on AR as a tool to study and improve building evacuation triggered by a variety of disasters such as fires, earthquakes or tsunami. Further, we provide an overview of application goals, existing hardware and what evacuation stages can be influenced by AR applications. Finally, we discuss strengths, weaknesses, and opportunities (SWOT) of AR to study evacuation behaviour and for research purposes.
