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.

Everyday Cloud !!

Cloud Computing - delivering hosted services over the Internet. Cloud computing is getting IT services, such as email, customer relationship management or web conferencing, over the internet.Instead of buying hardware and software up front, you pay a monthly charge based on the number of users.In simple words,when you  type a query into Google, the computer does nothing with regards to answer, it's just a messenger. The words you type are sent over the Net to one of Google's numerous clustered PCs, which find  your results and send them promptly back to you. The real work in finding your answers might be done by a computer sitting in California, Dublin, Tokyo, or Beijing!!Preparing documents over the Net is a newer example of cloud computing. Simply log on to a web-based service such as Google Documents and you can create a document, spreadsheet or presentation. Instead of typing your words into a program like Microsoft Word or OpenOffice, running on your computer, you're...

WHAT ARE SIM CARDS USED FOR

A SIM - short for Subscriber Identity Module - is a piece of plastic that slots into your  mobile phone.It acts as your unique ID and helps you  connect to, make calls over  a particular mobile phone network.Most SIM cards have a capacity between 32 to 128 KB.They store contacts and messages which can be transferred easily from one mobile to another. SIM also stores the ‘key’ needed to decrypt data that is encrypted when voice is trransfered from a phone to another.A unique ID called the IMSI (International Mobile Subscriber Identity)  is used to connect someone calling your mobile number to your phone. GSM phones are the ones that utilize SIM cards .The most important bits of data include the IMSI (International Mobile Subscriber Identity) and the authentication key that validates the IMSI. This authentication key is provided by the carrier SIM authentication goes like this: On startup, the phone obtains the IMSI from the SIM card and relays it to the network,k...
