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 consisti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Applications Of Virtual Reality
Virtual reality applications are applications that make use of virtual reality (VR), an immersive sensory experience that digitally simulates a virtual environment. Applications have been developed in a variety of domains, such as education, architectural and urban design, digital marketing and activism, engineering and robotics, entertainment, virtual communities, fine arts, healthcare and clinical therapies, heritage and archaeology, occupational safety, social science and psychology. Architecture and urban design One of the first recorded uses of virtual reality in architecture was in the late 1990s when the University of North Carolina virtually modelled Sitterman Hall, home of its computer science department. Designers wore a headset and used a hand controller to simulate moving around a virtual space. With an Autodesk Revit model they could "walk through" a schematic. VR enables architects to better understand the details of a project such as the transition of materials, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Reality Headset
A virtual reality headset (or VR headset) is a head-mounted device that provides virtual reality for the wearer. VR headsets are widely used with VR video games but they are also used in other applications, including simulators and trainers. VR headsets typically include a stereoscopic display (providing separate images for each eye), stereo sound, and sensors like accelerometers and gyroscopes for tracking the pose of the user's head to match the orientation of the virtual camera with the user's eye positions in the real world. Some VR headsets also have eye-tracking sensors and gaming controllers. The VR glasses use a technology called head-tracking, which changes the field of vision as a person turns their head. The technology may not be perfect, as there is latency if the head moves too fast. Still, it does offer an immersive experience. History The Sega VR, announced in 1991 and seen in early 1993 at the Winter CES, was never released for consoles, but was utilized fo ...

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, and whe ...

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, scientific c ...

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 gr ...

Avatar (virtual Reality)
In computing, an avatar is a graphical representation of a User (computing), user or the user's Player character, character or persona. Avatars can be two-dimensional Computer icon, 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 li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simulation
A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of Conceptual model, 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 computer simulation, 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 bu ...

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 experiementa ...

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-ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
