It is not a new idea, but it is a growing field of study. People have used cards, sticks, coins, bones, and heavenly bodies for hundreds of years trying to divine the future. Many of these past-times, such as the Chinese I Ching, the Tarot and astrology live on.
Share Virtual reality is, the projection upon the five senses artificial stimuli. This can be used to create illusions imaginary worlds that can be simulated on a computer.
Various technologies, especially computer games that utilize VR will incrementally reshape how we view society. Table of Contents [ show ] Definition "The ultimate dream is to merge the real world and the virtual world into a totally seamless experience" -- PhotoSynth project Development of simulation, rendering, VR input and output technologies will have wider implications than just better virtual environments.
We can define three main modes of combining reality with virtual reality: This information can also be used by robots for navigation in the real world. Scale and evolution Virtual reality started with single-player worlds simulated on a local machine first 3D games and research projects before that.
That is, computer games. The next step late s was to have multiplayer worlds, where several participants could interact with limited realism. These persistent worlds are running on clusters of servers sometimes distributed and usually allow creation of custom content and programming by users.
Overall more than million people play 3D computer and video games online 45 million in . The next step is going to be development of more open systems, where content can be moved across platforms and where separate worlds can be linked for example a room in a virtual building can be simulated on a private server using different simulation software, but would still be accessible for the people walking in the virtual city.
By then most of the people will spend a significant part of their lives in virtual reality playing, communicating, working, having sex. Eventually, uploading will make feasible a full migration into virtual reality, while robotic bodies will make the reverse possible.
Content acquisition Acquisition of data from aerial photos Acquisition from street level photos Manual content creation 3D city models in interactive maps, MS Virtual Earth 3D To bridge the gap between reality and virtual reality we need methods to quickly not slowly and manually  convert objects from physical reality into digital models and back.
This will have much wider implications than just more realistic games, this is going to gradually change what we consider reality. Some technologies already exist: Some crude methods already exist to quickly generate 3d models of larger real world scenes using image processing and LIDAR - urban landscapes      and indoor environments .
It is already feasible and cost-effective to acquire photographic data for Yellow Pages   using the "drive and shoot" model.
Google is quietly doing similar stuff and may do much more in the future    Using a combination of these approaches 3D models of cities will soon est. To create a realistic virtual environment one would only need to clean up the raw data a bit, combine the air photos for rooftops and large buildings with ground level images for details, add virtual pedestrians and traffic on streets.
Photosynth is an upcoming technology from Microsoft  videos, live demo, etc. In essense, it can take hundreds of photos of the Eiffel Tower from Flickr and automatically create a detailed 3D model. It is finally possible to simulate certain aspects of reality in real time and with sufficient precision to declare it an accurate simulation overall.
For example, the Forza Motorsport racing simulation for Xbox is physically realistic. To achieve this, programmers from Microsoft Game Studios take into account between and variables and simulate all aspects of driving, running the simulation at ticks per second.
For Race Against Reality Popular Science asked a veteran gamer and a professional race driver to extensively test drive both real cars and their virtual prototypes. The conclusion was that the game simulation is accurate.
Similar level of realism is available for the flight simulators, again from Microsoft . Some simulators are so realistic that pilots are allowed to log the virtual hours just like the real ones.
However, these simulations are not completely realistic yet. There are still things that can be improved though before we have perfect VR. One of the bigger problems is lighting and shadowing.
To make realistic materials technologies such as RealReflect need to be developed. Sound - there is still no good programmatic sound generation. Simulation of acceleration, tactile contact and everything else related to physically "being there". AI to make the world come alive The shader model introduced in made possible to move graphics a step up from poligonal textured environments to much more realistic worlds.
Games introduced in simulate realistically such superfluous details as raindrop splashes, smoke clouds Call of Duty 2etc.
Water shaders and 3D textures further enhance the realism. Still, we have already entered the realm of virtual reality. In some aspects, although not in all, virtual environments are already as good as real ones.
The Interface As of vision is the only area that is completely realistic in terms that it is indistinguishable from real life on a limited scale. Currently external stimulation is possible. Large VR gaming stations are being developed . Alternatively a user can wear glasses, headphones, virtual reality gloves.Virtual Reality: Bringing the Future Forward.
How do you simulate that in a virtual reality world?” Q&A with Jeremy Bailenson: Blurring the Line Between Reality and Illusion VR Today, AR Tomorrow What the Future Holds for Learning and Development SIGN UP.
The Magazine. We’re taking part in a preliminary KLM study into the behaviour of passengers wearing Virtual Reality (VR) headsets. Just imagine: while you, the passenger, are reading your information and watching games and movies in the virtual world, the cabin crew are serving meals or providing safety.
From people who know the gaming world. 3 Things To Know About the Future of Virtual Reality. Delegates use the Gear VR (virtual reality) headset, manufactured by Samsung Electronics Co., at.
The increased completeness will eventually make the virtual world real. In that virtual reality a "player" will be able to race, shoot, socialise, control armies, play with "physically real" objects and do a very large subset of what is possible in reality.
