Industry 5.0 emphasises how technology may benefit humans and marks a move towards a socio-technical paradigm. This study looks at how Augmented Reality (AR) can be integrated into human-centered smart manufacturing systems to improve operator performance, especially when it comes to assembly and disassembly work. Relevant AR applications in manufacturing are found through a methodical assessment of the literature, emphasising the necessity of human-centered design methodologies. The paper then offers basic recommendations for integrating AR systems into manual workstations in an efficient manner with the goal of enhancing operator productivity and welfare. The background, motivation and methods are discussed. The main findings include specific considerations for supporting the AR design in assembly, discussing the relevance of targeting group of users, choicing the suitable devices according to the usability and developing effective instructions.
