Virtual Reality (VR), which can be referred to as immersive multimedia or computer-simulated life, replicates an environment that simulates physical presence in places in the real world or imagined worlds. Virtual reality can recreate sensory experiences, which include virtual taste, sight, smell, sound, and touch. Most up to date virtual reality environments are displayed either on a computer screen or with special stereoscopic displays, and some simulations include additional sensory information and emphasise real sound through speakers or headphones targeted towards VR users. Concept origins[edit] The term "artificial reality", coined by Myron Krueger, has been in use since the 1970s; however, the origin of the term "virtual reality" can be traced back to the French playwright, poet, actor, and director Antonin Artaud.

Virtual environment software Virtual environment software refers to any software, program or system that implements, manages and controls multiple virtual environment instances. The software is installed within an organization's existing IT infrastructure and controlled from within the organization itself. From a central interface the software creates an interactive and immersive experience for administrators and users. Uses[edit] Virtual environment software can be purposed for any use. From advanced military training in a virtual environment simulator to virtual classrooms. Currently, virtual event and virtual tradeshow have been the early accepted uses of virtual event services. Background[edit] Providers of virtual environments have tended to focus on the early marketplace adoption of virtual events. Potential advantages[edit] Virtual environment software has the potential to maximize the benefits of both online and on-premises environments. Future[edit] Market availability[edit] See also[edit] References[edit]

What is VR Why Virtual Reality (VR)? A picture paints a thousand words... but an interactive VR simulation paints millions What is VR? Virtual reality can be many things to many men (and women). However, VR can trace its roots back to the 1860s, when in the art world, 360-degree panoramic murals (eg. Peruzzi's work "Sala delle Prospettive) started to appear. Moving a few decades on, stereographic photography started to become popular – and by the 1920s, car simulators were also being introduced. Today, computer based VR tends to be used at two levels: Interactive 3D virtual environments, or worlds Virtual artefacts, that is, objects such as a machine, device or historical object Our favourite (modern) definition of VR is: …It is a computer-generated, three dimensional environment where the user can move around freely, see and manipulate the content of the environment – one where all communication is interactive and with immediate response” Levels of VR This all sounds very impressive, doesn't it?

الحقيقة الإفتراضية Virtual Reality ظهر مصطلح الحقيقة الإفتراضية (Virtual Reality)لأول مره في عالم 1989 م واستطاع أن يدخل ويؤثر في مجالات عده ,, فها هو يؤثر في مجال التعليم والهندسه والأحوال الجويه وصناعة الألعاب والتسوق والعقارات وعلاج الأمراض النفسيه وإجراء العمليات الجراحية و إنتاج المواقع التي تعتمد على مبدأ هذه التقنية ,, فما هي الحقيقة الإفتراضية أو ما يطلق عليها أحياناً (VR) ؟الحقيقة الإفتراضية عباره عن محاكاة للحقيقة ,, والتركيز هنا يكون على الحقيقة الواقعيه ,,, وذلك عن طريق برامج مصممه بطريقة تسمح بإشراك حواس الإنسان فيما تعرض ,, بالإعتماد على أجهزة خاصة يتم توفيرها للمستخدم حتى يتصل بجهاز الحاسب ,,ويدخل في أجواء الحقيقة .. من هذه الأدوات ,, خوذة الرأس ,, أو غطاء الرأس ,, بحيث يرتديها المستخدم ويستمع للأصوات التي تصدر من العالم الإفتراضي ,,, وفي الغالب يكون مع الخوذة نظارات تغطي العينين بشكل كامل وتعرض الصور بشكل ثلاثي الأبعاد يجعل المستخدم يراها وكأنها واقع أمامه ,, و هناك قفازات لليدين وحذاء خاص يرتديه المستخدم حتى يتم تحديد موقع اليدين في الفضاء ومكان الشخص من المحيط ,,,وكذلك عصا التحكم وغيرها من الأدوات ,,

Sébastien "VR Geek" Kuntz » A Definition of VR Short definition Immersive Virtual Reality (iVR) is the science and technology required for a user to feel present, via perceptive, cognitive and functional immersion and interaction, in a generated environment. Introduction The term VR, Virtual Reality, seems now useless because it is too broadly defined and means different things to people. It ranges from any kind of 3D interactive application, to online metaverses like SecondLife, and finally to immersive VR. For me VR is Immersive Virtual Reality, the ultimate alternate reality we can get ! The terms ‘Immersion’ and ‘Presence’, which for me are essential for VR, are also now confusing, so let’s start by defining some fundamental concepts. - Fred Brooks asking the question, IEEE VR 2010 - Definitions Reality We could start be defining reality. Presence Then let’s define presence. The place illusion (PI) implies that your perception is fooled. The plausibility illusion (Psi) implies that your cognition is fooled. Immersion Immersive VR

Marvellous Murals History of Virtual Reality - where did it all begin? The History of Virtual Reality – otherwise known as VR. A term that applies to simulations made by technology in an environment that mimics the real world. Also as imaginary worlds. Most VR programs try to create a visual experience for its audience – a form of immersive entertainment. Today, it is being used in amusement parks and other entertainment environments. Way before the virtual reality movies that zap people into the monitors and become part of the gaming world, it was a concept that originated from the imagination of previous decades. Virtual Reality had become significantly popular during the 1990s. A number of people think that the Virtual Reality concept is something new. In 1961 a company decided to stick with a project called Headsight. During the 1980s and 90s, Virtual Reality became a concept that was been believed to be the future.

VIRTUAL REALITY - History Expo/Theater/Virtual Environments | Forward | Back | Map | Information | Expo Home | Beginnings Virtual reality may have popped into the headlines only in the past few years, but its roots reach back four decades. At the time, computers were hulking Goliaths locked in air-conditioned rooms and used only by those conversant in esoteric programming languages. But a young electrical engineer and former naval radar technician named Douglas Engelbart viewed them differently. Opportunity and timing At first, Engelbart's ideas were dismissed, but by the early 1960s other people were thinking the same way. Several pivotal events marked the decade: Courtesy SIGGRAPH Video Review Fear of nuclear attack prompted the U.S. military to commission a new radar system that would process large amounts of information and immediately display it in a form that humans could readily understand.
