Combination of Digital Twin and Augmented Reality: A Literature Review

The term digital twin has gained a lot of traction and has seen an increase in interest in recent years in both academia and industry. The concept of a digital twin allows a person to interact with a digital object that is created similarly to a physical object so that the interaction feels the same as interacting with a physical object. Synchronization of real-world behavior in a system known as the Cyber-Physical System. Often data is combined with a 3D Computer-Aided Design model to improve data visualization and make interactions more realistic. One of the tools that can be used in this visualization is Augmented Reality. Research on the combination of AR and digital twin is still a little done, even though the combination of the two technologies can promise interaction with virtual objects in the application of digital twin becomes more realistic so that in the process of monitoring, simulation, maintenance, and decision making can be more accurate. The main focus of this paper is how the framework or model of a combination of digital twin technologies and augmented reality can help with data and information understanding and decision making.
