Abstract: The present disclosure relates to methods, apparatus or systems for determining an aiming direction (22) of a remote motorized camera (10). The immersive video content captured by the camera (10) is associated with reference directions (13). Parameters of a discrepancy function (32, 42, 53) are calculated. This function is used to control the aiming direction (22) of the camera. It introduces a discrepancy between the rotation wanted by the user (21) and the rotation of the camera (22). An example purpose of the present disclosure is to encourage a user to rotate the camera toward reference directions, preventing him/her to rotate the camera toward the opposite direction. The present principles have the advantage to create pseudo-haptic effects, inciting the user to look toward a reference direction without making him/her sick.

Abstract: A method simulates behavior of a structure by finite element calculation in which a global model represents the structure, a local model represents an area of the structure including geometric details, and an auxiliary model represents the area without the geometric details. The method includes determining by finite element calculation in the global model of a nodal displacement field corresponding to a loading applied to the global model; applying the nodal displacement field to the local and auxiliary models and determining the corresponding forces; calculating a correction when convergence of the solution obtained for the global model is not achieved, and the applying is resumed with a nodal displacement field calculated in the global model after implementing the correction; determining values of internal variables for the different loading increments; and assessing the evolution in the behavior of the structure over time as a function of these values.
