VGuide: design and performance evaluation of a synchronous collaborative virtual reality application

The paper describes the design and operation of VGuide, a synchronous virtual reality tool that enables one user to lead a group of users synchronously through a virtual world written in VRML. VGuide employs the services of Pavilion, a middleware framework with support for developing collaborative Web based applications. The major components of VGuide and their interaction are described, followed by results of a performance study on a mobile computing testbed.
