Método y sistema para determinar una dirección de mirada actual

Donde el segundo punto de tiempo de muestreo es posterior al primer punto de tiempo de mirada; y determinar dicha dirección de mirada actual como una dirección de mirada modificada, calculada a su vez en base a la primera dirección de mirada, y calculada además en base a una inversa de dicha transformación 3D de cámara virtual dependiente del tiempo. La invención también se refiere a un sistema y a una computadora función de programa (Traducción automática con Google Translate, sin valor legal) Method for determining a current gaze direction of a user in relation to a three-dimensional ("3D") scene (10), which 3D scene is sampled by a rendering function to produce a two-dimensional ("2D") projection image of the 3D scene, which sampling is performed based on a virtual camera (20) in turn being associated with a camera position and camera direction in the 3D scene, wherein the method comprises the steps:determining, by a gaze direction detection means, a first gaze direction of the user at a first gaze time point (TG1), which first gaze direction is related to said 3D scene;determining a virtual camera 3D transformation, which 3D transformation represents a change of a virtual camera position and/or virtual camera direction between the first gaze time point and a second sampling time point (TR2), where the second sampling time point is later than the first gaze time point; anddetermining the said current gaze direction as a modified gaze direction, in turn calculated based on the first gaze direction, and further calculated based on an inverse of said time-dependent virtual camera 3D transformation.The invention also relates to a system and to a computer software function.
