Virtual Reality

Virtual reality is an artificial three-dimensional, computer generated environment which can be explored and interacted with by a person. .It  refers to a  type of reality emulation.
 That person becomes part of this virtual world and whilst there, is able to manipulate  objects or perform a series of actions. Virtual realities artificially create sensory experiences, which can include sight, touch, hearing, and smell.
There are a range of systems that are used for this purpose, such as headsets, omni-directional treadmills and special gloves.
These are used to actually stimulate our senses together in order to create the illusion of reality.
There are a wide variety of applications for virtual reality which include:
Architecture,Sport,Medicine,Arts,Entertainment.
From trainee fighter pilots to medical applications trainee surgeons, virtual reality allows us to take virtual risks in order to gain real world experience.
Virtual reality systems  allows a  person to view three-dimensional images,which appear life-sized to the person.
They change as the person moves around their environment which corresponds with the change in their field of vision , ensuring that the virtual environment is both realistic and enjoyable.
In a virtual reality environment, a user experiences immersion, or the feeling of being inside and a part of that world and also is able to interact with his environment . The combination of a sense of immersion and interactivity is called telepresence. Most virtual environment experiences prioritize visual and audio components over other sensory-stimulating factors, but a growing number of scientists and engineers are looking into ways to incorporate a users’ sense of touch. Systems that give a user force feedback and touch interaction are called haptic systems.
 Users wear an HMD or similar portable display while in the physical space. When they look toward the physical object, they'll see the virtual representation of it in their display. When they approach the object and try to touch it, they encounter the real object in the physical space. Anything a user does with that object in real space appears as a reflected action upon the virtual object in virtual space.

  1. Virtual reality has also been used widely to treat phobias (such as a fear of heights, driving, flying…). Also, it gives disabled people the opportunity to join in activities not usually available to them. For example, people in wheelchairs, can have a freedom of movement that they do not have in real world.

Fatal exception errors and how to fix them

              'A fatal exception XY has occured at xxxx:xxxxxxxx' What is it? A fatal exception error is an error that causes a program to abort,returning the user to the operating system.When program encounters an exception that is invalid or unknown,fatal exception error(fatal 0E) is thrown.It mainly occurs during the computer's booting process,shutdown process or while trying to launch a program in windows.The processor exception(XY value) ranges from  00 to 0F. xxxx:xxxxxxxx represents the 32-bit address where the actual exception has occured. 00-Divide fault 02-NMI interrupt 04-overflow trap 05-bounds check fault 07-coprocesser not available 08-double fault 09-coprocesser segment overrun 0A-invalid task state segment 0B-Not present fault 0C-stack fault 0D-general protection fault 0E-page fault 10-coprocessor error fault 11-Alignment check fault When it occurs?

Test your anti virus software with eicar

Do you want to check whether you have deployed your anti virus(AV) software correctly? Checking your AV software with real virus is risky!What if you have an option to test with a file which the AV software detects as if it were a virus,but actually it is non-viral? EICAR(European Institution for Computer Anti virus Research) provides Anti-malware test file for this purpose.It provides four test files to check your anti virus software.A good anti virus scanner will believe that the file is virus-infected. To download the anti-malware test files,visit this website Please feel free to post your comments.

How does Global Positioning System work?

The U.S. military developed and implemented GPS satellite network as a military radio-navigation system to figure out the exact position on the earth. It’s made up of three parts: satellites, ground stations, and receivers. GPS is  a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). Each satellite is built to last about 10 years. Each one transmits information about its position and the current time at regular intervals.These satellites make two complete rotations around the globe everyday such that at any point of time atleast four satellites are visible to the receiver. The basis of GPS is "trilateration".Trilateration is a method of determining the relative positions of objects using the geometry of triangles.In order to make this simple calculation, the GPS receiver has to know the location of at least three satellites and the distance between our receiver and each of those satellites. The signals, moving at the speed...
