Immersion in Virtual Reality

"The state of consciousness where...awareness of physical self is diminished or lost by being surrounded om am engrossing total environment; often artificial."

This is the definition of the term 'Immersion', given by Joseph Nechvatal, 1999

Once we enter the virtual world, immersion takes place. We become so involved that we forget what is happening in the outside world and we feel a connection within the world of virtual reality. Immersion makes us feel as if we are involved in the game. Our eyes become fixed on the screen and our real life surroundings become less important.

According to Ernest Adams, there are 3 states of immersion. These are; narrative, strategic and tactical.

Narrative Immersion - This type of immersion occurs when players become invested in a story.You can experience this immersion by watching a movie or reading a book.

Strategic Immersion - This type of immersion is more analytical and challenges the brain. Strategic immersion occurs amongst chess players. It is slow paced and enables players to think carefully about their next move/decision.

Tactical Immersion - This requires skill and players feel "in the zone" with this type of immersion. Tactical immersion can be found in fast paced games.

Osmose

An example of immersion in a virtual reality game is Char Davis' Osmose. It is an interactive virtual reality environment installation with 3D computer graphics and interactive 3D sound. Immersion in Osmose begins by putting on a head-mounted display and a motion tracking vest. Immersants are then able to travel through this virtual world and their movement is based in their breathing and balance. They are completely immersed in a digital environment.

Here is a video showing the walk through of Osmose.
