When monitoring a student, the student can always ask Steve to demonstrate a recommended action. Thus, VR supports a natural and flexible collaboration between student and tutor. Distributed VR and VRML The idea behind distributed VR is very simple; a simulated world runs not on one computer system, but on several.
The computers are connected over a network (possibly the global Internet) and people using those computers are able to interact in real time, sharing the same virtual world. In theory, people may be stationed anywhere in world at different locations, all interacting in a meaningful way in VR.
