A system for determining the gaze endpoint of a subject, the system comprising: a eye tracking unit adapted to determine the gaze direction of one or more eyes of the subject; a head tracking unit adapted to determine the position comprising location and orientation of the eye tracker with respect to a reference coordinate system; a 3D Structure representation unit, that uses the 3D structure and position of objects of the scene in the reference coordinate system to provide a 3D structure representation of the scene; based on the gaze direction, the eye tracker position and the 3D structure representation, calculating the gaze endpoint on an object of the 3D structure representation of the scene or determining the object itself.

Method and an apparatus for determining a gaze point on a three-dimensional object

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 () in relation to at least one scene recording (S) of a scene () viewed by the at least one person () is mapped onto a reference (R). At least a part of an algorithm (A, A, A) for performing the eye gaze mapping (M) is thereby selected from multiple predetermined algorithms (A, A, A) 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 (A, A, A).

Method and device for carrying out eye gaze mapping

The invention relates to a method for evaluating at least one view image (M) in order to image at least one viewpoint, which is provided in relation to at least one scene shot (S) of a scene (), and/or at least one view direction of at least one person (), said view direction being provided in relation to the at least one scene shot (S), towards a reference, the content of which matches at least one part of the scene (). The at least one scene shot (S) is provided with the at least one assigned viewpoint (B) and/or the at least one assigned view direction, and the reference (R) is provided together with a result (B') of the at least one view image (M). Furthermore, the at least one view image (M) is evaluated by means of at least one predefined quality measurement (GM), and the result of the evaluation is provided.

Method and device for evaluating view images

The invention relates to a method and a head mounted eye tracking device () for determining at least a feature of an eye (), wherein the eye tracking device () comprises a capturing device (C) for capturing light reflected by the eye () and an optical component (; E, E, En, E) capable of altering a propagation direction of the light passing through the optical component (; E, E, En, E). The eye tracking device () 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 (; E, E, En, E) 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 () and the head mounted eye tracking device ().

Head mounted eye tracking device and method for providing drift free eye tracking through a lens system

The invention relates to a method and an apparatus for evaluating results of gaze detection, wherein these results are present or are obtained in the form of information which defines, for each of a multiplicity of successive times, a viewing direction detected at this time and a focal point identified thereby in a scene image assigned to this time. For this purpose, the invention provides for the following steps to be carried out: &#x2014;a temporal change in the viewing direction and/or the focal point is evaluated in order to identify different viewing events which differ from one another by different speeds of an eye movement, wherein saccades and fixations and/or pursuit movements are detected as different types of viewing events and the identified viewing events are classified according to the type thereof, &#x2014;a period of time spanned by the times is divided into intervals in such a manner that an interval corresponding to a duration of the particular viewing event is assigned to each of the identified viewing events, wherein at least some of these intervals each contain a sequence of a plurality of times, &#x2014;precisely one of the times or a true subset of the times is selected in each case from each of the intervals assigned to a fixation or a pursuit movement, &#x2014;and, for each of these selected times, the focal point identified in the scene image assigned to the particular time is mapped to a position corresponding to this focal point in a reference image.

Method and apparatus for evaluating results of gaze detection

An apparatus for mapping a gaze point of a subject on a scene image to a gaze point in a reference image, wherein said scene image and said reference image have been taken by a camera from a different position, said apparatus comprising: A module for executing a feature detection algorithm on said reference image to identify a plurality of characteristic features and their locations in said reference image; a module for executing said feature detection algorithm on said scene image to re-identify said plurality of characteristic features and their locations in said scene image; a module for determining a point transfer mapping that transforms point positions between said scene image and said reference image based on the locations of said plurality of characteristic features detected in said reference image and said scene image; a module for using said point transfer mapping to map a gaze point which has been determined in said scene image to its corresponding point in said reference image.
