Extended Reality
Extended reality (XR) is both an umbrella term to refer to and interpolate between augmented reality (AR), mixed reality (MR), and virtual reality (VR), as well as to extrapolate (extend) beyond these, e.g. allowing us to see sound waves, radio waves, and otherwise invisible phenomena. The technology is intended to combine or mirror the physical world with a "digital twin world" able to interact with it, giving users an immersive experience by being in a virtual or augmented environment. XR is rapidly growing beyond an academic discipline, and is now having real-world impact in medicine, architecture, education, industry, and is being applied in a wide range of areas such as entertainment, cinematic virtual reality, cinema, marketing, real estate, manufacturing, education, maintenance and remote work. Extended reality has the ability to be used for joint effort in the workplace, training, educational purposes, therapeutic treatments, and data exploration and analysis. Extend ...

Umbrella Term
Hypernymy and hyponymy are the wikt:Wiktionary:Semantic relations, semantic relations between a generic term (''hypernym'') and a more specific term (''hyponym''). The hypernym is also called a ''supertype'', ''umbrella term'', or ''blanket term''. The hyponym names a subset, subtype of the hypernym. The semantic field of the hyponym is included within that of the hypernym. For example, "pigeon", "crow", and "hen" are all hyponyms of "bird" and "animal"; "bird" and "animal" are both hypernyms of "pigeon", "crow", and "hen". A core concept of hyponymy is ''type of'', whereas ''instance of'' is differentiable. For example, for the noun "city", a hyponym (naming a type of city) is "capital city" or "capital", whereas "Paris" and "London" are instances of a city, not types of city. Discussion In linguistics, semantics, general semantics, and ontology components, ontologies, hyponymy () shows the relationship between a generic term (hypernym) and a specific instance of it (hyponym ...

Augmented Reality
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, ...

Virtual Reality
Virtual reality (VR) is a Simulation, 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, 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 creat ...

Digital Twin
A digital twin is a digital model of an intended or actual real-world physical product, system, or process (a ''physical twin'') that serves as a digital counterpart of it for purposes such as simulation, integration, testing, monitoring, and maintenance. A digital twin is set of adaptive models that emulate the behaviour of a physical system in a virtual system getting real time data to update itself along its life cycle. The digital twin replicates the physical system to predict failures and opportunities for changing, to prescribe real time actions for optimizing and/or mitigating unexpected events observing and evaluating the operating profile system. Though the concept originated earlier (as a natural aspect of computer simulation generally), the first practical definition of a digital twin originated from NASA in an attempt to improve the physical-model simulation of spacecraft in 2010. Digital twins are the result of continual improvement in modeling and engineering. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinematic Virtual Reality
Cinematic virtual reality (Cine-VR) is an immersive experience where the audience can look around in 360 degrees while hearing spatialized audio specifically designed to reinforce the belief that the audience is actually in the virtual environment rather than watching it on a two-dimensional screen. Cine-VR is different from traditional Virtual Reality which uses computer generated worlds and characters more akin to interactive gaming engines, while cine-VR uses live images captured thorough a camera which makes it more like film. When storytellers began working in cine-VR, they applied many of the same cinematic narrative rules, but the technology demonstrated that VR can offer different possibilities that go beyond "traditional" cinema which will require new techniques and practices. Harrison Weber, journalist of ''Venturebeat'', described cine-VR like this: "It's a lot like film, only it puts the audience inside your story. With it, you can create entire worlds for your audience ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Work
Remote work (also called telecommuting, telework, work from or at home, WFH as an initialism, hybrid work, and other terms) is the practice of work (human activity), working at or from one's home or Third place, another space rather than from an office or workplace. The practice of working at home has been documented for centuries, but remote work for large employers began on a small scale in the 1970s, when technology was developed which could link satellite offices to downtown mainframes through dumb terminals using telephone lines as a network bridge. It became more common in the 1990s and 2000s, facilitated by internet technologies such as collaborative software on cloud computing and conference calling via videotelephony. In 2020, workplace hazard controls for COVID-19 catalyzed a rapid transition to remote work for white-collar workers around the world, which largely persisted even after restrictions were lifted. Proponents of having a geographically distributed workforc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edge Computing
Edge computing is a distributed computing model that brings computation and data storage closer to the sources of data. More broadly, it refers to any design that pushes computation physically closer to a user, so as to reduce the Latency (engineering), latency compared to when an application runs on a centralized data centre. The term began being used in the 1990s to describe Content Delivery Network, content delivery networks—these were used to deliver website and video content from servers located near users. In the early 2000s, these systems expanded their scope to hosting other applications, leading to early edge computing services. These services could do things like find dealers, manage shopping carts, gather real-time data, and place ads. The Internet of Things (IoT), where devices are connected to the internet, is often linked with edge computing. Definition Edge computing involves running computer programs that deliver quick responses Locality of reference, close to ...

Hyperreality
Hyperreality is a concept in post-structuralism that refers to the process of the evolution of notions of reality, leading to a cultural state of confusion between signs and symbols invented to stand in for reality, and direct perceptions of consensus reality. Hyperreality is seen as a condition in which, because of the compression of perceptions of reality in culture and media, what is generally regarded as real and what is understood as fiction are seamlessly blended together in experiences so that there is no longer any clear distinction between where one ends and the other begins. The term was proposed by French philosopher Jean Baudrillard, whose postmodern work contributed to a scholarly tradition in the field of communication studies that speaks directly to larger social concerns. Postmodernism was established through the social turmoil of the 1960s, spurred by social movements that questioned preexisting conventions and social institutions. Through the postmodern lens, r ...

User Interface Techniques
An interaction technique, user interface technique or input technique is a combination of hardware and software elements that provides a way for computer users to accomplish a single task. For example, one can go back to the previously visited page on a Web browser by either clicking a button, pressing a key, performing a mouse gesture or uttering a speech command. It is a widely used term in human-computer interaction. In particular, the term "new interaction technique" is frequently used to introduce a novel user interface design idea. Definition Although there is no general agreement on the exact meaning of the term "interaction technique", the most popular definition is from the computer graphics literature: A more recent variation is: The computing view From the computer's perspective, an interaction technique involves: * One or several input devices that capture user input, * One or several output devices that display user feedback, * A piece of software ...
