Joint manipulation management in collaborative virtual environments

Some international standards have been developed that are very likely to make a major impact on CVE (Collaborative Virtual Environment) technology: the Distributed Interactive Simulation (DIS) (IEEE Standard 1278.1) and the High Level Architecture (HLA) (IEEE Standard 1516). Deriving from military-purpose simulations, DIS and HLA, however, have limitations on building large-scale general-purpose CVE applications. For instance, HLA object-attribute based ownership management only allows joint manipulation in a constraint-based solution. The purpose of this research effort is to realize joint manipulation management in CVE. This paper begins with a discussion of interaction requests and interaction model and proceeds to describe three generic approaches for joint manipulation management: Constraint-based, Synchronized and Non Synchronized.
