Virtual Reality
Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings). Other distinct types of VR-style technology include augmented reality and mixed reality, sometimes referred to as extended reality or XR, although definitions are currently changing due to the nascence of the industry. Currently, standard virtual reality systems use either virtual reality headsets or multi-projected environments to generate 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 consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damien Broderick
Damien Francis Broderick (born 22 April 1944) is an Australian science fiction and popular science writer and editor of some 74 books. His science fiction novel ''The Dreaming Dragons'' (1980) introduced the trope of the generation time machine, his ''The Judas Mandala'' (1982) contains the first appearance of the term "virtual reality" in science fiction, and his 1997 popular science book '' The Spike'' was the first to investigate the technological singularity in detail. Life Broderick holds 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. He was for several years a Senior Fellow in the School of Culture and Communication at the University of Melbourne. Broderick lives in San Antonio, Texas, with his wife, tax attorney Barbara Lamar.

Haptic Technology
Haptic technology (also kinaesthetic communication or 3D touch) is technology that can create an experience of touch by applying forces, vibrations, or motions to the user. These technologies can be used to create virtual objects in a computer simulation, to control virtual objects, and to enhance remote control of machines and devices (telerobotics). Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface. The word '' haptic'', from the grc-gre, ἁπτικός (''haptikos''), means "tactile, pertaining to the sense of touch". Simple haptic devices are common in the form of game controllers, joysticks, and steering wheels. Haptic technology facilitates investigation of how the human sense of touch works by allowing the creation of controlled haptic virtual objects. Most researchers distinguish three sensory systems related to sense of touch in humans: cutaneous, kinaesthetic and haptic. All perceptions mediated by cutaneous an ...

Reality Check ESA384313
Reality is the sum or aggregate of all that is real or existent within a system, as opposed to that which is only imaginary. The term is also used to refer to the ontological status of things, indicating their existence. In physical terms, reality is the totality of a system, known and unknown. Philosophical questions about the nature of reality or existence or being are considered under the rubric of ontology, which is a major branch of metaphysics in the Western philosophical tradition. Ontological questions also feature in diverse branches of philosophy, including the philosophy of science, philosophy of religion, philosophy of mathematics, and philosophical logic. These include questions about whether only physical objects are real (i.e., physicalism), whether reality is fundamentally immaterial (e.g. idealism), whether hypothetical unobservable entities posited by scientific theories exist, whether a 'God' exists, whether numbers and other abstract objects exist, ...

Antonin Artaud
Antoine Marie Joseph Paul Artaud, better known as Antonin Artaud (; 4 September 1896 – 4 March 1948), was a French writer, poet, dramatist, visual artist, essayist, actor and theatre director. He is widely recognized as a major figure of the European avant-garde. In particular, he had a profound influence on twentieth-century theatre through his conceptualization of the Theatre of Cruelty. Known for his raw, surreal and transgressive work, his texts explored themes from the cosmologies of ancient cultures, philosophy, the occult, mysticism and indigenous Mexican and Balinese practices. Early life Antonin Artaud was born in Marseille, to Euphrasie Nalpas and Antoine-Roi Artaud. His parents were first cousins—his grandmothers were sisters from Smyrna (modern day İzmir, Turkey). His paternal grandmother, Catherine Chilé, was raised in Marseille, where she married Marius Artaud, a Frenchman. His maternal grandmother, Mariette Chilé, grew up in Smyrna, where she married Lou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Graphics
Computer graphics deals with generating images with the aid of computers. Today, computer graphics is a core technology in digital photography, film, video games, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of computer science research. Some topics in computer graphics include user interface design, sprite graphics, rendering, ray tracing, geometry processing, computer animation, vector graphics, 3D modeling, shaders, GPU design, implicit surfaces, visualization, scien ...

3D Computer Graphics
3D computer graphics, or “3D graphics,” sometimes called CGI, 3D-CGI or three-dimensional computer graphics are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images. The resulting images may be stored for viewing later (possibly as an animation) or displayed in real time. 3D computer graphics, contrary to what the name suggests, are most often displayed on two-dimensional displays. Unlike 3D film and similar techniques, the result is two-dimensional, without visual depth. More often, 3D graphics are being displayed on 3D displays, like in virtual reality systems. 3D graphics stand in contrast to 2D computer graphics which typically use completely different methods and formats for creation and rendering. 3D computer graphics rely on many of the same algorithms as 2D computer vector ...

Avatar (virtual Reality)
In computing, an avatar is a graphical representation of a user or the user's character or persona. Avatars can be two-dimensional icons in Internet forums and other online communities, where they are also known as profile pictures, userpics, or formerly picons (personal icons). Alternatively, an avatar can take the form of a three-dimensional model, as used in online worlds and video games. The term ' () originates from Sanskrit, and was adopted by early computer games and science fiction novelists. Richard Garriott extended the term to an on-screen user representation in 1985, and the term gained wider adoption in Internet forums and MUDs. Nowadays, avatars are used in a variety of online settings including social media, virtual assistants, instant messaging platforms, and digital worlds such as ''World of Warcraft'' and ''Second Life''. They can take the form of an image of one's real-life self, as often seen on platforms like Facebook, or a virtual character that div ...

Simulation
A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning, as in economics. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not ...

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. The experiments give Jobe superhuman abilities, but also increase his aggression, turning him into a man obsessed with evolving into a digital being. This film is adapted from the merging of a 1975 short story by Stephen King with an original screenplay entitled "CyberGod." While King's story focused on the titular character, a demon-possessed devil-worshipper who strips naked and eats grass like a goat, who can control his lawnmower with mystical powers, the film has the same character controlling the lawnmower by means of the untapped potential of the human brain, which has been stimulated by advanced, but unethical scientific experiement ...

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 1999 all of its patents were bought by Sun Microsystems. 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 program the microcontrollers. The system was wired to a computer. It was interactive and contained fiber-optic bundles to track movements and orientation. That data would then be transmitted to the computer so that the information could be duplicated virtually. It allowed for people to manipulate and re-or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
