In this webinar, the speaker will describe the ever-changing puzzle of the Metaverse explaining its critical component technologies and their corresponding basic fundamentals. Initially, the audience will have the opportunity to learn more about the eXtended Reality (XR) spectrum and identify the differences between Augmented (AR) & Virtual Reality (VR) and how these experiences can be developed atop a popular Game Engine. After that, I will showcase how XR, virtual environments, gamified tools, simulations and can be combined with the Internet of Things, Artificial Intelligence and other technologies to create various tools like digital twins, virtual triggers or synthetic data generators and solve research or industry problems. I will summarize various custom-made implementations that have been developed along with their potential impact in different domains (automotive industry, distance learning) and ideas for new research directions.
