    Abstract: A method for determining a current gaze direction of a user in relation to a three-dimensional (“3D”) scene, the 3D scene sampled by a rendering function to produce a two-dimensional (“2D”) projection image of the 3D scene, the sampling performed based on a virtual camera in turn being associated with a camera position and camera direction in the 3D scene. The method includes determining, by a gaze direction detection means, a first gaze direction of the user related to the 3D scene at a first gaze time point. The method includes determining a time-dependent virtual camera 3D transformation representing a change of a virtual camera position and/or virtual camera direction between the first gaze time point and a second sampling. The method includes determining the current gaze direction as a modified gaze direction calculated based on the first gaze direction and an inverse of the time-dependent virtual camera 3D transformation.

    Abstract: Method for determining a current gaze direction of a user in relation to a three-dimensional (“3D”) scene, 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 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, 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, where the second sampling time point is later than the first gaze time point; and determining 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.

    Abstract: A method for panning content on a display of a wearable device is disclosed. The method may include determining, via an eye tracking device, a gaze direction of a user. The method may also include determining, via a movement detection system, a head direction of the user. The method may further include, based at least in part on the gaze direction and the head direction both being consistent with a particular direction, causing content displayed on a display of the wearable device to be panned in the particular direction. The method may additionally include determining during panning of the content, via the eye tracking device, that the gaze direction of the user has returned to a neutral position. The method may moreover include, based at least in part on the gaze direction of the user returning to the neutral position, causing content displayed on the display to stop panning.

    Abstract: According to the invention, a method for providing audio to a user is disclosed. The method may include determining, with an eye tracking device, a gaze point of a user on a display. The method may also include causing, with a computer system, an audio device to produce audio to the user, where content of the audio may be based at least in part on the gaze point of the user on the display.

    Abstract: A method for determining if a user's gaze is directed in the direction of a zone of interest in a 3D scene comprises: providing a 3D scene containing a zone of interest; associating a property with the zone of interest; creating a bitmap representing the location of the zone of interest in a projected view of the 3D scene, each pixel of the bitmap to which the zone of interest is projected storing the property of the zone of interest; detecting the direction of the user's gaze; using the bitmap to determine if the detected user's gaze is directed in the direction of the zone of interest.
