Virtuality
Virtual reality (VR) is a simulated experience that employs 3D near-eye displays and pose tracking to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical, safety, or military training) and business (such as virtual meetings). VR is one of the key technologies in the reality-virtuality continuum. As such, it is different from other digital visualization solutions, such as augmented virtuality and augmented reality. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate some realistic images, sounds, and other sensations that simulate a user's physical presence in a virtual environment. A person using virtual reality equipment is able to look around the artificial world, move around in it, and interact with virtual features or items. The effect is commonly created by VR headsets consisting of a hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reality–virtuality Continuum
The virtuality continuum is a continuous scale ranging between the completely virtual, a virtuality, and the completely real, reality. The reality–virtuality continuum therefore encompasses all possible variations and compositions of real and virtual objects. It has been described as a concept in new media and computer science. The concept was first introduced by Paul Milgram. The area between the two extremes, where both the real and the virtual are mixed, is called mixed reality. This in turn is said to consist of both augmented reality, where the virtual augments the real, and augmented virtuality, where the real augments the virtual. This continuum has been extended into a two-dimensional plane of ''virtuality'' and ''mediality''. 2002 August 6th, Presence C ...

Reality Check ESA384313
Reality is the sum or aggregate of everything in existence; everything that is not imagination, imaginary. Different Culture, cultures and Academic discipline, academic disciplines conceptualize it in various ways. Philosophical questions about the nature of reality, existence, or being are considered under the rubric of ontology, a major branch of metaphysics in the Western intellectual tradition. Ontological questions also feature in diverse branches of philosophy, including the philosophy of science, philosophy of religion, religion, philosophy of mathematics, mathematics, and philosophical logic, logic. These include questions about whether only physical objects are real (e.g., physicalism), whether reality is fundamentally immaterial (e.g., idealism), whether hypothetical unobservable entities posited by scientific theories exist (e.g., scientific realism), whether God exists, whether numbers and other abstract objects exist, and whether possible worlds exist.

Virtual (philosophy)
Virtuality is a concept with a long history in philosophy, its most notable recent version being that developed by French thinker Gilles Deleuze. Overview Deleuze used the term virtual to refer to an aspect of reality that is ideal, but nonetheless real. An example of this is the meaning, or sense, of a proposition that is not a material aspect of that proposition (whether written or spoken) but is nonetheless an attribute of that proposition. In ''Bergsonism'', Deleuze writes that "virtual" is not opposed to "real" but opposed to "actual", whereas "real" is opposed to "possible". Deleuze identifies the virtual, considered as a continuous multiplicity, with Bergson's " duration": "it is the virtual insofar as it is actualized, in the course of being actualized, it is inseparable from the movement of its actualization." Deleuze argues that Henri Bergson developed "the notion of the ''virtual'' to its highest degree" and that he based his entire philosophy on it. Both Henri Bergson, ...

Augmented Virtuality
Augmented reality (AR), also known as mixed reality (MR), is a technology that overlays real-time 3D computer graphics, 3D-rendered computer graphics onto a portion of the real world through a display, such as a handheld device or head-mounted display. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersion (virtual reality), immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, compared to virtual reality, which aims to completely replace the user's real-world environment with a simulated one. Augmented reality is typically visual, but can span multiple sensory Modality (human–computer interaction), modalities, including Hearing, auditory, haptic perception, haptic, and Somatosensory system, somatosensory. The primary value of augmented reality is the manner in which components of a digital world blend into a person's perception of the real world, ...

VPL Research
VPL Research was one of the first companies that developed and sold virtual reality products. It was founded by computer scientist Jaron Lanier in 1984. "VPL" stood for "Virtual Programming Languages". In 1990, VPL Research filed for bankruptcy and in 1998 all of its patents were bought by Sun Microsystems Sun Microsystems, Inc., often known as Sun for short, was an American technology company that existed from 1982 to 2010 which developed and sold computers, computer components, software, and information technology services. Sun contributed sig .... VPL's funding came in part from Marvin Minsky. Products The DataGlove This device originally started as an input system for computers. It was later used for virtual reality systems. Thomas Zimmerman invented the prototype of the DataGlove and began looking for other people to help work on it. The device used 6502 microcontrollers. Zimmerman met Mitch Altman and asked him to join VPL part-time because Altman knew how to pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myron W
Myron of Eleutherae (480–440 BC) (; , ''Myrōn'' ) was an Athenian sculptor from the mid-5th century BC. Alongside three other Greek sculptors, Polykleitos Pheidias, and Praxiteles, Myron is considered as one of the most important sculptors of classical antiquity. He was born in Eleutherae on the borders of Boeotia and Attica. According to ''Natural History'', a Latin encyclopedia by Pliny the Elder (AD 23 – 79), a scholar in Ancient Rome, Ageladas of Argos was his teacher. None of his original sculptures are known to survive, but there are many later copies of his works, such as his '' Discobolus'', mostly Roman. Reputation Myron worked almost exclusively in bronze and his fame rested principally upon his representations of athletes (including his iconic '' Diskobolos''), in which he made a revolution, according to commentators in Antiquity, by introducing greater boldness of pose and a more perfect rhythm, subordinating the parts to the whole. Pliny's remark that Myron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damien Broderick
Damien Francis Broderick (22 April 1944 – 19 April 2025) was an Australian science fiction and popular science writer and editor of some 74 books. ''The Encyclopedia of Science Fiction'' credits him with the first usage of the term ''virtual reality'' in science fiction, in his 1982 novel ''The Judas Mandala.'' Background Broderick held a Ph.D. in Literary Studies from Deakin University, Australia, with a dissertation (''Frozen Music'') comparing the semiotics of scientific, literary, and science fictional textuality.

The Lawnmower Man (film)
''The Lawnmower Man'' is a 1992 science fiction horror film directed by Brett Leonard, written by Leonard and Gimel Everett, and starring Jeff Fahey as Jobe Smith, an intellectually disabled gardener, and Pierce Brosnan as Dr. Lawrence "Larry" Angelo, a scientist who decides to experiment on him in an effort to give him greater intelligence by stimulating his brain using nootropic drugs and virtual reality computer simulations. The experiments give Jobe superhuman abilities, but also increase his aggression, turning him into a man obsessed with evolving into a digital being. The film was originally marketed as the adaptation of a 1975 short story by Stephen King, which featured a Pan-worshipping satyr using his mystical powers to operate a landscaping business and mow lawns. Allied Vision began developing the film after a planned adaptation of King's book '' Night Shift'' (1978), an anthology the story was published in. However, it struggled to expand King's original sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
