Virtual Reality for surgical training is mainly focused on technical surgical skills. We work on providing a novel approach to the use of Virtual Reality focusing on the procedural aspects. Our system relies on a specific work-flow generating a model of the procedure from real case surgery observation in the operating room. This article presents the different technologies created in the context of our project and their relations as other components of our workflow.

In this paper we present a novel approach to role modelling for Collaborative Virtual Environments with an Action Oriented Scenario Engine. Our role model is able to take into account different data about the actions such as the abilities, rights or resources required by an actor to determine whether he or she can execute an action. Furthermore, it considers that any data about an actor can have an influence on his or her role in the simulation. We provide also a team organisation model to… Voir plus

Our role model is able to take into account different data about the actions such as the abilities, rights or resources required by an actor to determine whether he or she can execute an action. Furthermore, it considers that any data about an actor can have an influence on his or her role in the simulation. We provide also a team organisation model to define the impacts of the rules of the team on the role of the actors as suggested by the role theory. To illustrate our work, we used our model in a Collaborative Virtual Environment for the Training of a neurosurgery procedure. Voir moins

Currently, the scenario of a virtual reality application depends greatly of the representation of the virtual environment and the goals of the application. Different needs arise from these elements such as the abstraction level of their events, the presence of multiple actors or their freedom of action. In this paper, we propose a scenario engine model that aims at being used in any virtual reality application where the scenario is a key feature. It differs from other models as it can be used… Voir plus

Currently, the scenario of a virtual reality application depends greatly of the representation of the virtual environment and the goals of the application. Different needs arise from these elements such as the abstraction level of their events, the presence of multiple actors or their freedom of action. In this paper, we propose a scenario engine model that aims at being used in any virtual reality application where the scenario is a key feature. It differs from other models as it can be used without making any assumption on the simulation purpose or on the modelling of the Virtual Environment (events model, objects behaviour). Voir moins

In this paper we present #SEVEN, a sensor effector model that enables the execution of complex scenarios for driving Virtual Reality applications. #SEVEN is based on an enhanced Petri net model which is able to describe and solve intricate event sequences. Our model also proposes several useful features for the design of collaborative scenarios for Collaborative Virtual Environments such as versatile roles and Activity Continuum. We also illustrate its usage it by describing a demonstrator that… Voir plus
