Player Collaboration in Virtual Environments Using Hierarchical Task Network Planning

In recent years, the fast evolution in computer games has moved government organizations to investigate how they can be exploited as virtual environments to simulate scenarios which could be expensive or even dangerous to set up in real life, in particular when collaboration among humans is required in order to carry out a shared plan. The proposed system allows the tracking of progresses achieved by each plan participant within the planning domain, by mapping its steps to states and humans' actions in the virtual environment.
