Artificial reality is a concept that comprises a range of virtual environments and experiences that are created through advanced technology. There are several synonyms to describe variations of this concept, including virtual reality, augmented reality, mixed reality, and simulated reality. Virtual reality is an immersive experience that uses a headset or a screen to create a simulated 3D environment. Augmented reality blends digital elements with the real world, while mixed reality allows users to interact with both real and virtual worlds. Simulated reality is an entirely computer-generated experience that mimics reality. These synonyms highlight the sophisticated technology that has enabled the creation of environments and experiences that blur the line between the real and the virtual world.
