La Realidad Virtual es la tecnología que permite sumergir a un usuario en un ambiente tridimensional simulado por el computador, de forma interactiva y autónoma en tiempo real.

De esta forma, por medio de la realidad virtual se puede estar en lugares y situaciones simuladas, sin estar físicamente en ellos.

La realidad virtual nos lleva a lugares cotidianos desde una nueva perspectiva, a sitios reales de difícil, por no decir imposible acceso, e incluso a mundos imaginarios de leyes arbitrarias.

Virtual Reality suggests 3-D?

Magritte, R. (1955). Les Promenades d’Euclide.

Magritte also suggests 3-D

Optical illusion 1: Canvas is window

Optical illusion 2: Triangle lies down (road)Triangle stands up (tower)

Virtual Reality suggests 3-D?

game environments

Dalí also suggests 3-D

Dalí, S. (1937). Cygnes reflétant des éléphants

Optical illusion:Swans reflect elephants

Virtual Reality is computer generated?

The following animationalso is computer generated

Does that make theanimated agent VR?

Virtual Reality is interactive,also with other users?

Well, what do you think about theseforce-feedback devices?

Virtual Reality is immersive?

In surroundings, but so is a haunted house

Emotionally, but so can acting be

Acting in Playback

".... my deep curiosityand desire to be on the Playback stage shookmy entire body"

Makoto Tange (Tama) writes about his experience of playback acting

What we learned from the foregoing:

VR is not technology

VR is not a rendering technique

VR is not reality but a fiction genre

VR is an experience of fiction as if it were real

Thus, VR is fiction with many features judged realistic

*Truth test by whatever belief system: Religion, science, culture

Virtual Reality is the experience of fiction as if it were real

Virtual Reality can evoke the experience of immersion, theextreme outcome of an Involvement-Distance trade-off

Fiction is less consequential for daily life

Therefore, VR has lessemotional relevance

Because Virtual Reality hasless emotional relevance,it is functional for safely exploringdangerous, expensive, andfantastic situations.

La Realidad Virtual es la tecnología que permite sumergir a un usuario en un ambiente tridimensional simulado por el computador, de forma interactiva y autónoma en tiempo real.

De esta forma, por medio de la realidad virtual se puede estar en lugares y situaciones simuladas, sin estar físicamente en ellos.

La realidad virtual nos lleva a lugares cotidianos desde una nueva perspectiva, a sitios reales de difícil, por no decir imposible acceso, e incluso a mundos imaginarios de leyes arbitrarias.

Making VR more immersive,raising more involvementis increasing personal relevanceof the experience rather thanrendering hyper-realistic features.

Relevance is increasedby touching upon thegoals and concerns of theuser.

Relevance is increased by touching upon the goals and concerns of the user.

Perfectly realistic featuresare not always useful

Perfectly relevant featuresalways are even when unrealistic

DNA molecular structure

E.g., color distinctions

In designing a VR-experience, the strive for ‘augmented reality’ should better be for ‘augmented relevance’

Augmenting relevance should be done not so much by increasing the number and quality of realistic features but by increasing the personal meaning of a simulated (work) situation, providing featuresthat tune in to the goals and concerns of the user

To do so, requirements engineering for VR-systems should begin with relevance assessment
