# Industrial Metaverse: A Comprehensive Review, Environmental Impact, and Challenges
## 4 Use Cases and Deployment
Employees and trainees can take advantage of the Dynamics 365 Guides' more sophisticated features, which include pre-join settings for HoloLens users joining Teams calls that let them turn on or off their audio and video before joining the session. During the meeting, users can also change these settings. This allows frontline staff to use the HoloLens as their primary calling device in settings where secrecy is paramount without compromising security. The Dynamics 365 Guides simplify document navigation. Through action steps, this also offers the additional capability of linking straight from one guide to another. One has to click on hyperlinks to get to different online pages, and this enables easy switching between various training materials or manuals. These cutting-edge training techniques provide a secure and monitored environment for practical learning, which boosts productivity, reduces costs, and improves safety in industrial settings. The fifth use case for the IM is sales and marketing for product production. The Metaverse enables one to create virtual product experiences that allow customers to visualize and engage with merchandise within a virtual setting. The Metaverse has opened up many opportunities for businesses to market their goods by organizing virtual product launches using the Metaverse to launch brand-new products. Companies can create virtual launch events where users can virtually experience the new products, learn about their features, and even pre-order them. This creates buzz and anticipation among their customer bases. Virtual factory tours help customers connect with the brand. This allows them to experience the manufacturing process and get an opportunity to view the facilities without physically visiting the factories. Virtual booths at trade shows can showcase products to a global audience. These booths can engage visitors and demonstrate the products using virtual presentations, videos, or interactive demos. Virtual trade shows offer a cost-effective and environmentally friendly way to market products and reach potential customers globally. The sixth use case emphasizes development and research. With its immersive and collaborative features, IM applications have changed the way that industries undertake research and development (R & D). In the end, this results in new inventions, effectiveness, and inventiveness. Classically, physical prototypes have been used to conduct R & D on products that were not only time-consuming, but costly as well. The IM simulates the design of a product or service at a very early stage as a cost-effective design approach. It enables the design team to swiftly change course and select the optimal and most suitable design options. The production of early-stage products employing the Metaverse would be an ideal, \"low-hanging fruit\" use case for industries [50]. The Ford Motor Company is a typical example. It has been investigating how to leverage the Metaverse for research and development in fields like car design, safety testing, and manufacturing efficiency. They have built virtual prototypes of their vehicles and tested them virtually for performance and safety using VR simulations.
