For distance education purposes, distributed VR is useful. Virtual Reality system can be networked to support multiple-user immersion environments joined over long distances. The sites implementing VR technology must be networked using low band modem-to-modem over telephone lines, the Internet, and high bandwidth telecommunications.
The emergence of the Virtual Reality Modeling Language (VRML) as a standard method of modeling virtual reality objects and worlds coupled with the wide spread deployment of WWW browsers that support VRML allows the creation of such distributed virtual environments, which can be accessed through Internet. This paves the way for participation of more geographically dispersed users in multi-user virtual reality interface systems.
