“…They argued that the fundamental characteristic of a digital twin is the two-way mapping of a physical entity and the digital-twin model. This was also argued by Lei et al, 25 who pointed out that the synchronized communication between physical systems and the digital twin for data and information exchange is the key feature of a digital twin, which implies that the digital twin should operate in the same way as the physical system. Conventional simulation models, however, differ from digital twin in this perspective because they are designed by applying assumptions or preconditions to physical systems.…”

“…quoted the definition of digital twin from Industrial Internet Consortium as “a formal digital representation of some asset, process, or system that captures attributes and behaviors of that entity suitable for communication, storage, interpretation or processing within a certain context.” They argued that the fundamental characteristic of a digital twin is the two‐way mapping of a physical entity and the digital‐twin model. This was also argued by Lei et al., 25 who pointed out that the synchronized communication between physical systems and the digital twin for data and information exchange is the key feature of a digital twin, which implies that the digital twin should operate in the same way as the physical system.

A virtual qualification (VQ) model is proposed using a digital twin not only for verifying electrical properties of a liquid crystal display (LCD) but also for assessing the effect of environmental stresses. The digital twin is developed to reflect product specifications and distributions of manufacturing process data. The VQ model utilizes the digital twin to infer and verify the changes in electrical characteristic values in the internal circuit under a high‐temperature operating test. Additionally, a procedure is proposed for developing digital twins, and its effectiveness is demonstrated based on a case study of an LCD. The developed digital twin may also be used for similar LCD models for design verification.

ReImagine Lab: Bridging the Gap Between Hands-On, Virtual and Remote Control Engineering Laboratories Using Digital Twins and Extended Reality

Practical work is one of the most important instructional tools in control engineering. To address concerns linked to the cost and space requirements of traditional hands-on laboratories, technology-enabled laboratory modes, such as virtual, remote, and take-home laboratory modes are proposed. Each of these alliterative laboratory modes has its own set of benefits and emphasizes a distinct learning goal. Furthermore, due to lockdown and physical proximity restrictions imposed by policies in response to the COVID-19 pandemic, the employment of these alliterative laboratory modes has been quickly increasing. The laboratories' development, operation, and maintenance become more fragmented as a result of these many possibilities. In this study, we propose "ReImagine Lab" as a framework for leveraging digital twins and extended reality technologies to streamline the development and operation of hands-on, virtual, and distant laboratories. By increasing the level of interaction, immersion, and collaboration in technologyenabled laboratory forms, this framework intends to boost student engagement. The benefits of this framework are demonstrated by examining several use cases, and a 37-person "system usability study" is conducted to assess the usability of virtual laboratories employing desktop computers and immersive virtual reality.
