Extended reality in industry: past, present and future perspectives

Abstract The industry's interest in Virtual and Augmented Reality (VR and AR) technologies started from the beginning of their appearance in the research world. Over the years, scholars observed ups and downs, to which various factors contributed. In recent years these technologies, now known as eXtended Reality (XR), have returned to fascinate the industrial world, mainly because most of the related enabling technologies have improved to the point of pushing companies to re-invest in them. The introduction of approaches such as the digital twin one and the recent hype on the metaverse is also a push in this direction. A few questions arise: what are the benefits of such technologies in the industry today, and what are the unexplored possibilities? Starting from a systematic literature review and exploring the practical implications of integrating technologies in the industrial field, the paper tries to answer these questions. The paper is not intended as a technological forecast but as a stimulus for future research.
