Definition of Virtual Reality (RV)
What is Virtual Reality?
How can we define something that in itself is contradictory?: ¿The Virtual Real?
A paradigm evolves from birth incorporating new resources and new questions associated with them is not easily conceptualization and, accordingly, its definition is subject to further revisions.
There are many interpretations that come close to the different aspects that contains the concept of RV.
Approaches vary based on a description of the words, uses or the means used. What is?, What's the point?, What used?, How do?…seems that it is to answer these questions in each case.
Many definitions use the term “simulation” possibly due to their use in traditional simulators for training in fields of aviation and medicine.
Setting concepts (enviroment) and world (world) are associated in these cases significantly (simulation requires an environment that represent the objects(??) simulated), but turn themselves emphasize the concept immersive visual appearance mainly.
These two views, simulation and virtual worlds, added a new confusion to the concept referring to the first inert object focus or central, while in the second case we are at the center of the scene that surrounds us while we live new worlds.
By introducing the definitions interaction added words that describe the necessary equipment:
“It is a technology that allows users to interact with a computer-simulated environment” [ALA00].
Generic terms are added “devices” or “peripheral”, or specific as “gloves”, “Helmets”… but more important is the input of the measurement of response time in the interaction: Real time??
But immersion requires other perceptions that are purely visual and auditory. Extending the definition is sometimes remarkable:
“Realistic three-dimensional simulation (Stereoscopic) with computer, Real time, space and physical objects. Used in training and entertainment, VR allows the user “interact” and have sensory experiences of the actors, images and sounds by sensors attached to your body that record their movements.” [HTT01].
Just register their moving? Temperature??Pulse??…The information capture “reality” and becomes part of the data used in “the virtual” is another growing phenomena.
The user interacts receiving increasing variety of responses: visual, hearing, touch, olfactory…Being represented senses greatly facilitating the immersion on different scales.
When I asked my son for the concept, surprised me with its simplicity:
“Visual representation of an environment with great dive 4d“
It seemed as if he who is just read the article titled Jonathan Steuer “Defining VR: Dimensions Determining Telepresence”, which synthesizes three-step concept: Presence, Telepresence and finally virtual reality.
- Presence is defined as the sense of being in an environment.4 [GIB79]
- Telepresence is defined as the experience of presence in an environment by means of a communication medium. [JON93]
- A “virtual reality” is defined as a real or simulated environment in which a perceiver experiences telepresence.
If we understand “Audiovisual” (across the board to all human senses) as a means of communication that transmits sensations or emotions, and “Telepresence” or experience through symbolism presence of the terms “4d” and “immersion” to describe the space time and the perceptual aspect, synthesis of the phrase is at least striking.
The term “Representation” used at the beginning of the sentence indicates that it is not real, that virtual, but which in turn shows a support represented reality, emphasizing the concept of “medium”.
How difficult is deciding on a definition, but perhaps, and simply to provoke more discussion, me one to “4d”
“Sensory representation 4d immersive environment“
