Abstract: The invention relates to a device and a method for performing an eye gaze mapping (M), in which at least one point of vision (B) and/or a viewing direction of at least one person (10) in relation to at least one scene recording (S) of a scene (12) viewed by the at least one person (10) is mapped onto a reference (R). At least a part of an algorithm (A1, A2, A3) for performing the eye gaze mapping (M) is thereby selected from multiple predetermined algorithms (A1, A2, A3) as a function of at least one parameter (P), and the eye gaze mapping (M) is performed on the basis of the at least one part of the algorithm (A1, A2, A3).

Abstract: The invention relates to a method and a head mounted eye tracking device (10a, 10b) for determining at least a feature of an eye (12), wherein the eye tracking device (10a, 10b) comprises a capturing device (C) for capturing light reflected by the eye (12) and an optical component (14; E, E1, En, E2) capable of altering a propagation direction of the light passing through the optical component (14; E, E1, En, E2). The eye tracking device (10a, 10b) is configured such that when fixed to the head of the user the light captured by the capturing device (C) has passed through the optical component (14; E, E1, En, E2) and constitutes at least part of an image and the feature is determined on the basis of the image in dependency of an information about a relative position between the eye (12) and the head mounted eye tracking device (10a, 10b).
