Modeling Reality with Virtual Worlds

Virtual Reality makes it possible to experience anything, anywhere, anytime. It can convince the human brain that it is somewhere it is really not.Virtual reality isn't just for gaming - it's a technology that can make a real difference to our collective futures.

 Virtual Worlds have a great importance for training and education in fields like medicine, engineering, and the sciences. Medicine is one of the biggest beneficiaries with the development of surgery simulation. This is often used as a training aid and enables the surgeon to perform an operation on a virtual patient. It's better and safer for surgeons in training to perfect their techniques on things other than real humans. The article Avatar II: The Hospital tells us that online simulations are teaching nurses to make the right and quick decisions in emergencies. Another popular use of virtual reality is aviation: a three dimensional aircraft can be designed which allows the designer to test their prototype without having to spend a lot of money. Also, you can look back in time and visit ancient sites, such as the Acropolis in Athens or the Western Wall in Jerusalem. Or you can dive deep and go underwater to visit famous places.

 But there are disadvantages of virtual reality. First of all, it is expensive and it can cause addiction and health damage. Virtual World is much more entertaining than the world you live in, so you may grow an addiction to it. Also, it can change the way you behave in real life. As I read in the article Virtual world may impact real world behavior: "Our results indicate that just five minutes of role play in virtual environments as either a hero or villain can easily cause people to reward or punish anonymous strangers".

 It’s possible to create your own three-dimensional virtual reality environments, if you are wealthy enough to do so. Just imagine the unreal things and create the story, which can lead our society to make new discoveries.

Blog: Next New

New media is quickly changing thing. It always replace the old and come up with the new. I would like to offer a new "new media" device. Such that it will allow users to be present near each other even if they are far away. For example, if you are in New York and your friend is in Paris, you will press the button on the new device and you will be "transferred" to Paris. It will copy your projection and transfer it to any place you want. And your friend will see the projection of you walking near himself. Maybe it will be the device, that will replace our computers and phones. I found some pictures to show how it should work.

Blog: Privacy

            New media affects the society in the negative way. There is a huge problem with security, hacking and fraud.  Nowadays security agencies have access to people's personal accounts. Which makes the privacy almost compromised.  Personal data and privacy can easily be hacked and shared through the Internet.  Automatic face recognition can lead to the theft of personality, because it shares your private information to a large amount of users. Social media network should limit the function of face recognition to some extent or use it only in special cases, not on daily basis. Social networks must pay attention to how they use photos and bio-metric data because there is nothing more personal or susceptible to identification than a person’s face and private information. Nowadays a lot of security agencies have an access to people personal accounts, which makes the privacy very suspicious. Social media often store, share and cop...

Blog: Advice

There are few ways in which new media can be used to improve Baruch College: We can put the large screens on each floor of college. So that every student will be able to search the number of the classroom he have. We can add screens with adds in the elevators. The advertisements will include: MBA programs, athletic teams, hand made classes, training and so on. We can create a website to book computers in the library or seats in the dinning area.  We can a blog, where everyone will find their classmates and unite with them in groups.
