A Survey of Techniques and Architectures for Extended Reality Computing

Extended Reality (XR) is a huge trend in recent years. It collects Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality(MR). This survey aims to give a presentation and an overview of the world of Extended Reality. We will go through different fields of application exploring related research. In particular this survey explores, for each field, definitions and different configurations in order to elaborate a general visualization of the kind of works the scientists are into. In detail, in each field we present different works related to that topic and at the end we have one or more tables to collect information about XR set ups. Consequently we have created a tree that summarizes the most used technology faced during the explorations of all the researches in each field.
