In virtual reality (VR), immersion is the perception of being physically present in a non-physical world. The perception is created by surrounding the user of the VR system in images, sound or other stimuli that provide an engrossing total environment.

👉 Immersion (virtual reality) in the context of Augmented virtuality
Augmented reality (AR), also known as mixed reality (MR), is a technology that overlays real-time 3D-rendered computer graphics onto a portion of the real world through a display, such as a handheld device or head-mounted display. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, compared to virtual reality, which aims to completely replace the user's real-world environment with a simulated one. Augmented reality is typically visual, but can span multiple sensory modalities, including auditory, haptic, and somatosensory.
The primary value of augmented reality is the manner in which components of a digital world blend into a person's perception of the real world, through the integration of immersive sensations, which are perceived as real in the user's environment. The earliest functional AR systems that provided immersive mixed reality experiences for users were invented in the early 1990s, starting with the Virtual Fixtures system developed at the U.S. Air Force's Armstrong Laboratory in 1992. Commercial augmented reality experiences were first introduced in entertainment and gaming businesses. Subsequently, augmented reality applications have spanned industries such as education, communications, medicine, and entertainment.

Immersion (virtual reality) in the context of Virtual reality game
A virtual reality game or VR game is a video game played on virtual reality (VR) hardware. Most VR games are based on player immersion, typically through a head-mounted display unit or headset with stereoscopic displays and one or more controllers.
The video game industry made early attempts at VR in the 1990s, most notably with Sega's VR-1 and Virtuality for arcades, along with unsuccessful attempts for home consoles with the Sega VR prototype and Nintendo's Virtual Boy. With the introduction of the first consumer-ready home VR product, the Oculus Rift, in 2013, home VR games soon followed, including existing games adapted for the VR hardware, and new games designed directly for VR. While VR hardware and games grew modestly for the remainder of the 2010s, Half-Life: Alyx, a full VR game developed by Valve and released in 2020, was considered the killer application for VR games.
Immersion (virtual reality) in the context of Virtual world
A virtual world (also called a virtual space or spaces) is a computer-simulated environment which may be populated by many simultaneous users who can create a personal avatar and independently explore the virtual world, participate in its activities, and communicate with others. These avatars can be textual, graphical representations, or live video avatars with auditory and touch sensations. Virtual worlds are closely related to mirror worlds.
In a virtual world, the user accesses a computer-simulated world which presents perceptual stimuli to the user, who in turn can manipulate elements of the modeled world and thus experience a degree of presence.Such modeled worlds and their rules may draw from reality or fantasy worlds. Example rules are gravity, topography, locomotion, real-time actions, and communication. Communication between users can range from text, graphical icons, visual gesture, sound, and rarely, forms using touch, voice command, and balance senses.
