An example of how iWorld could be used is as a virtual school. You could build the virtual school starting with a hallway. On either side of the hallway there will be doors to classrooms and offices. On the doors of the classrooms (course names such as Electronic I Theory or Digital Logic II) will be signs that indicate the program discussions that are going on .
Inside the classrooms, the participants will display their usernames above their virtual bodies. To chat with someone, you move towards them and use their usernames.
The instructor's offices will have a desk with the instructor's name on it. If the instructor is in, there will be a virtual instructor present. If the instructor is out, there will be no one present.
