XR, or Extended Reality, is an umbrella term that encompasses various immersive technologies, including Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). These technologies blend the physical and digital worlds, allowing users to interact with computer-generated environments or overlay digital information onto the real world. XR is used in various fields, such as gaming, education, and healthcare. For example, in education, XR can create interactive learning experiences, while in healthcare, it can assist in training medical professionals through realistic simulations. This versatility makes XR a powerful tool for enhancing experiences and improving skills across different industries.
