Human Factors Issues in Augmented Reality-Assisted Manual Order Picking: A Systematic Literature Review

Augmented reality (AR) has gained popularity as an assistive technology for providing cognitive support during warehousing operations such as order picking. Several research studies have explored the use of AR in manual order picking and found mixed outcomes in terms of both cognitive and physiological human factor aspects. Methods: This study is part of a larger systematic review assessing the use of AR, which aimed to identify the current body of knowledge relevant to the effectiveness of AR technology in enhancing safety, performance, and user satisfaction for order-picking tasks. The literature search was done following the PRISMA methodology. After the search, 24 studies were found to be eligible for the full-text analysis. Results: The review showed that AR gadgets have beneficial and detrimental effects on order pickers' cognitive and physiological systems. Several concerning issues are reported: visual fatigue, headaches, dizziness, discomfort, and cause of distraction. On the other hand, the benefits reported are increased speed, reduced error, flexibility, adaptability, safety, and new technology. Conclusion: The use of AR in manual order picking has benefits that can reduce overall warehousing costs and improve order picking performance. However, some ergonomic concerns need to be addressed to improve user comfort and acceptance. Application: The outcome of this review will help researchers and practitioners find the current status and future direction of the use of AR in manual order picking.
