Table 4 Brief description of immersive extended reality (XR) technologies

Virtual reality (VR)

It immerses users within fully simulated environments, effectively disconnecting them from the physical world.

Through specialized devices (e.g., headsets and hand controllers) users gain the ability to explore and engage with these digital spaces, in a real-time interaction.

Augmented reality (AR)

It overlays digital content onto the tangible world via devices like smartphones, tablets, or AR glasses.

AR technology enables users to simultaneously perceive both their physical surroundings and the digital elements, resulting in interactive experiences that enhance real-world environments.

Mixed reality (MR)

It amalgamates the attributes of VR and AR, empowering users to interact with virtual objects that seemingly coexist with their physical environment.

MR fosters a heightened level of interaction and integration between digital and real-world components, reshaping the way people engage with their surroundings.
