What is Virtual Reality?

Users questions:
Experts answer: words to help you understand: the game of houses, weapons, characters are a reflection of the virtual reality simply say ah : VR (VirtualReality) is short for virtual reality, the technology was originally developed in the United States military Research out of a computer technology. VR VR technology in the media is to present the most potential for development of information media, Internet and other digital element media (eg CD-ROM CD-ROM, touch screen, etc.). Through its proprietary software to integrate images, sound, animation, will be three-dimensional reality, objects such as two-dimensional simulation The form of virtual reality, and then by the number of dollars the media as a carrier transmitted to people. When people browse through the media, immersive viewing time as a general, and can choose any point of view, watching any of the options within the scene or object of any point of view. Virtual reality can simulate the real world, More importantly, it had a computer in the virtual paradise of our dreams, people will have a vast virtual space, in between entertainment! Virtual reality is most important and most attractive feature is the fact, and interaction time. Virtual reality technology will give people a whole new perspective, we can imagine a more colorful The virtual three-dimensional scene, some have a real three-dimensional digital body "person" in the conversation during the work. Said Professional: Virtual reality is that in computer graphics, computer simulation technology, human-machine interface technology, multimedia technology and sensor technology developed on the basis of cross-disciplinary, the technology The study began in the 20th century 60s. Until the early 90s, started as a virtual reality a more complete system and by people of great concern. Basic concept in a nutshell, virtual reality is people through computer visualization of complex data operation and a whole new way to interact with the traditional Man-machine interface, and the popular Windows operating compared to the technology of virtual reality has been a qualitative leap in thinking. Virtual reality "real" generally refers to the physical or functional sense, meaning the existence in the world of anything or Huan Jing, it can be actually achievable, can be actually realized in or Genben Nanyi Can not be achieved. The "virtual" refers to computer-generated meaning. Therefore, virtual reality is a computer generated special circumstances, one can Tongguoshiyong a variety of special Zhuangzhi to Zi Ji "projecting" Dao Zhe Ge environment in, and operation, control environment, to achieve specific objectives, which as is the environment the master . In essence, virtual reality is an advanced computer user interface, it also provides passed to the user, such as visual, auditory, tactile, and other intuitive and natural interaction, real-time sensing means, to maximize user-friendly operation. According to the application of virtual reality technology at different targets, the effect could Manifested in different forms, for example, a conceptual design or operational concept of visualization and to achieve realistic effects of the remote site, to any complex environment of low-cost simulation training purposes . The main features of the technology are the following: Multi-Sensory (Multi-Sensory) - the so-called In addition to the general perception is more computer technology with visual perception, there are auditory perception, force sensing, tactile sensing, motion sensing, and even taste perception, olfactory perception and so on. Virtual reality technology ideal person should have all the functions with perception. As related technologies, particularly sensor technology Operation constraints, the current virtual reality technology has the perception function is limited to visual, auditory, force, touch, movement and so are several. A sense of immersion (Immersion) - also known as telepresence, means users are present in the simulated environment as a hero in the true extent. Ideal simulation environment should enable users to hard To distinguish between true and false, so that the user himself into the computer to create three-dimensional virtual environment, the environment all seem to be true, it sounds really, really moving up, or even smell, taste and all feelings are real, as in the real world feel the same. Interaction (Inter activity) - refers to the user objects within the simulated operational environment, the extent and nature of feedback from the environment level (including real-time). For example, users can directly hand to grab the virtual objects in the simulated environment, then shook hands with the feeling of things, and can feel the weight of the object, the View Objects can be caught with the hand movements immediately move. Imagination (Imagination) - stressed that virtual reality technology can be a wide imagination, can broaden the scope of human cognition, not only can reproduce real environment, but also free to ideas that do not exist objectively or impossible to send
