Lec 5 Virtual Philosophy

Today’s lecture focuses on virtual reality.

Virtual Reality is a system that enables one or more users to move and react in a computer-simulated environment. Various types of devices allow users to sense and manipulate virtual objects much as they would real objects. This natural style of interaction givesparticipants the feeling of being immersed in the simulated world. Virtual worlds are created by mathematical models and computer programs. There are some types of VR: 3D simulation on computer screen, control generally by mouse or joystick, utilizes VRML or similar program to give the sensation of moving through an environment. Due to this lecture is partial to theory, teacher shows us video to explain the virtual reality. The video is amusing; it presented a ‘real world” in the computer. For example, the popular game second life, people in the fabricate world can do exactly things just like in the real world. In that game, people can earn money, go to bar, shopping etc. and do business with the people who are from around world. Meanwhile, people can adjust their appearance they like and take adventure in the different places.





IM program is simple and easy to use compare with the 3D environment. Usually, I only use MSN to communicate with family and friends. Sometimes, I write blog or upload photos to share my life with my friends. However, 3D environment is more unique. People can choose their own appearances and personality; even they can choose their own special talents in the 3D environment. Due to people face lots of stresses from their work and life, more and more people are willing to choose 3D environment because 3D environment can help them reduce the stresses. For example, a friend of mine is infatuated with 3D environment games. He said that the 3D environment is exactly same as our real world, and you can do anything what you want or like in the virtual world. It can satisfy your desire in that world. However, 3D environment is not perfect. It wastes our time and energy. Some teenagers addictive on 3D environment, and did criminal and finally ruin their own life.
