Concept
Immersion (virtual reality)
Summary
Immersion into virtual reality (VR) is a 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.
The name is a metaphoric use of the experience of submersion applied to representation, fiction or simulation. Immersion can also be defined as the state of consciousness where a "visitor" (Maurice Benayoun) or "immersant" (Char Davies)'s awareness of physical self is transformed by being surrounded in an artificial environment; used for describing partial or complete suspension of disbelief, enabling action or reaction to stimulations encountered in a virtual or artistic environment. The greater the suspension of disbelief, the greater the degree of presence achieved.
According to Ernest W. Adams, immersion can be separated into three main categories:
Tactical immersion: Tactical immersion is experienced when performing tactile operations that involve skill. Players feel "in the zone" while perfecting actions that result in success.
Strategic immersion: Strategic immersion is more cerebral, and is associated with mental challenge. Chess players experience strategic immersion when choosing a correct solution among a broad array of possibilities.
Narrative immersion: Narrative immersion occurs when players become invested in a story, and is similar to what is experienced while reading a book or watching a movie.
Staffan Björk and Jussi Holopainen, in Patterns In Game Design, divide immersion into similar categories, but call them sensory-motoric immersion, cognitive immersion and emotional immersion, respectively. In addition to these, they add a new category: spatial immersion, which occurs when a player feels the simulated world is perceptually convincing. The player feels that he or she is really "there" and that a simulated world looks and feels "real".
Presence, a term derived from the shortening of the original "telepresence", is a phenomenon enabling people to interact with and feel connected to the world outside their physical bodies via technology.
