  • Patent number: 11398162
    Abstract: Monitoring a training session from a trainee in an interactive computer simulation system. During the training session, while the trainee performs actions in an interactive computer simulation station on one or more tangible instruments thereof for controlling a virtual simulated element, dynamic data is logged related to the actions of the trainee. At a monitoring station of the interactive computer simulation system and during the training session, a graphical user interface is displayed depicting a contextual scene related to the interactive computer simulation from a first point of view and detecting a predetermined event in the dynamic data during the training session. At the monitoring station, a second point of view is defined different from the first point of view and the contextual scene is generated in the graphical user interface after the predetermined event detection from the second point of view.

  • Patent number: 11288340
    Abstract: A method and computer system for dynamically updating a model associated to a simulated interactive object in an interactive computer simulation comprising a computer generated environment. In real-time, a simulated behavior of the simulated interactive object is provided considering the model associated thereto. After reception of a request to modify the model, a new model is determined and validated by computing a validation indicator. The validation indicator computation considers interrelated parameters associated to the model and simulated constraints associated to the computer generated environment. The model is then selectively and dynamically updated into a new model considering at least the validation indicator. Subsequently, in real-time, an updated simulated behavior of the simulated interactive object is provided correspondingly considering the model or the new model associated thereto.
