Exploring the performance of an augmented reality application for construction layout tasks

A review of augmented reality systems and their effects on mental workload and task performance

“…A drawback of presenting the data in this method is that it fails to show the frequency of same effects. For example, 6 studies found significant positive effects on both mental workload and task performance [9] , [12] , [13] , [27] , [30] , [57] . However, this is not reflected in the graph.…”

“…Based on findings from the review of the selected studies, generally, AR can reduce mental workload by facilitating the perception of instruction. AR's primary capability to augment relevant virtual information upon the real world enhances perception and understanding of information in instances where the operator would have to refer to secondary sources of information, such as a secondary display or paper-based instructions [8] , [12] . The extent of the effectiveness of AR systems in reducing mental workload and enhancing task performance is also affected by: type of AR device used [29] , relevance of content, AR presentation [30] , [45] , user characteristics, task characteristics, and environmental characteristics.…”

“…With the support of AR, mental activities related to the searching and interpretation of information needed to perform a task is mitigated, and the only effort required is related to the actual execution of the task [59] . Users or operators would not need to perform typical actions or steps which would otherwise incur more physical and/or mental effort, such as taking measurements, marking positions [12] , contextual switching [11] , searching for information [8] , remembering information [14] , confirming instructions [60] and such. This offloading of mental effort is suggested to relieve time demanding mental activities and result in lower mental and temporal demands, contributing to an overall lower NASA-TLX rating [59] .…”

“…By using AR to provide visual guidance and task-relevant information where and when needed, cognitive workload could be reduced, users would be subjected to lower cognitive demands and thus improve task performance. Indeed, some studies reported positive effects of AR use on both mental workload and task performance [12] , [13] . However, there are also studies that reported positive effects on mental workload yet negative effects on task performance [8] , [14] .…”

An Investigation of Virtual Reality Technology Adoption in the Construction Industry

“…Utilizing augmented 360-degree panoramas help users increase their hazard identification in the construction job sites [10]. Utilizing AR to deliver design layout to the electrical construction practitioners in a faster way with less mental and physical demand requirements [46], and utilizing the AR glasses for the users who are working in an assembly construction line [47] Analyzing tool Developing a framework to increase the efficiency of maintaining and developing gas and oil facilities by utilizing AR [48] people's thoughts about adopting new technologies in other companies in the same industries. Facilitating conditions considers the functions of modern technology to simplify the existing conditions rather than complicate them.…”
