Immersion, as complete as possible, is the keyword of virtual reality. But it is not without dangers, and is not necessary in general.
Immersion is a form of human-computer interaction where the user's vision field is totally composed by generated images and frequently "surround" sound, plus possibly haptics and odors. Such an environment is obtained
- by a dedicated room (cave)
- with goggles, gloves and possibly a full suit.
Immersion is typical of virtual reality.
Beware: consraints are heavy. In some case, an excessive immersion may be dangerous:
- loss of contact with the external real worls,
- disharmony between external perception (vision) and internal (internal ear and its slant sensors, for instance),
- excessive stimulation, see for instance our note about our note about an immersive work by Kurt Hentsclhager.
- A full book by [Rose, 2011], who says for instance: "... immersiveness is what blurs the line, not just between story and game, but between story and marketing, story teller and audience, illusion and reality" (p. 15)
- A full chapter (56 pages) in [Leloup, 2013].
