Augmented reality aided object mapping for worker assistance/training in an industrial assembly context: Exploration of affordance with existing guidance techniques

Impact of Augmented Reality on Assistance and Training in Industry 4.0: Qualitative Evaluation and Meta-Analysis

“…More recently, research has highlighted the benefits of AR in improving assembly performance. For instance, AR-assisted object mapping has been shown to facilitate worker assistance and training, significantly improving efficiency and reducing error rates compared to other guidance methods [85]. Other research has addressed real-time occlusion processing for AR assembly assistance systems using monocular imaging [83], the creation of AR-assisted hands-on experiences to enhance assembly line performance [54] and AR systems that facilitate dynamic gesture recognition and prediction [64].…”

“…However, the large study sample mitigates any negative effect on the overall results, maintaining a low risk of bias assessment. [40,41,42,46,51,60,62,68,72,77,85,86,88,91].…”

“…However, upon analysis, a significant heterogeneity was detected among them. This variability was due to factors such as the population studied, the methodological design and the metrics used, which in some cases led to an [40][41][42]46,51,60,62,68,72,77,85,86,88,91].…”

“…Further reflection on the underlying causes of these limitations leads us to ponder the contemporary challenges in integrating this technology into the training and care settings. [40,41,42,46,51,60,62,68,72,77,85,86,88,91].…”

“…Given the notable heterogeneity identified in the meta-analysis (Q = 90.84, I 2 = 86% > 75%, p < 0.00001), a sensitivity analysis was performed to validate the accuracy of the results obtained. This analysis was conducted on the 14 studies, excluding those that demonstrated significant differences [42,60,62,68,85,91]. In order to assess the possible variations in overall effect sizes, the aforementioned studies were excluded.…”
