Modeling Reality with Virtual Worlds

          I learned about some purposes of the Virtual reality for the first time, when I was a student ambassador for a Technology launch in Pennsylvania. Moreover, there was a survey about 3D virutal glass in my Business class so that all the people in the class were able to try on that eyewear, which functions as a display device. I was able to see many different projected environment like space, desert, and etc., and felt like I was actually there. Virtual worlds can be used in many different ways and can be beneficial for many purposes. Like Knafo describes in the article "In room 100, It's Side and Nancy All over Again", 3D virtual world called Second Life was able to recreate the famous Chelsea Hotel with old photographs even though the hotel was renovated in recent years. Also, Tutton mentions about the creating a tool that allows virtual meetings and effective collaboration in businesses (CNN).

         The pros would be VR's ability to break down the boundaries imposed on us. People now can explore more about the things that they were not able to see or learn before with the help of virtual worlds. It is not just on science movies like before. The cons would be the security issues for the people and society as everyone can see or learn things that they were able to see before. Future world would rely on technology even more than today. With advanced virtual worlds, I think there will not be any barriers and boundaries for the differences.
