    Abstract: 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.

    Abstract: The invention relates to an eye tracking device (10a; 10b; 10c) comprising a processing unit (18) and an optical system (14), which comprises a capturing unit. The optical system (14) provides a first optical path (P; P1) with a first imaging property and a second optical path (P; P2) with a second imaging property and the capturing unit (C; C1, C2) captures a first image (24a) by capturing light that has passed along the first optical path (P; P1) and a second image (24b) by capturing light that has passed along the second optical path (P; P2), so that due to the difference of the first and second imaging property the first (24a) and the second image (24b) comprise a difference related to a characteristic of at least part of the first and the second image (24b), wherein the eye tracking device (10a; 10b; 10c) is configured to determine a property of the eye (12) on the basis of at least one of the first image (24a) and the second image (24b).

    Abstract: The invention relates to a method for determining at least one parameter of two eyes (10l, 10r) of a test person (31), the method comprising the following steps: optically capturing of a first eye (10l; 10r) of the two eyes (10l, 10r) by means of a first capturing unit (3l; 3r); optically capturing the second eye (10r; 10l) of the two eyes (10l, 10r) by means of a second capturing unit (3r; 3l); transmitting first signals concerning the captured first eye (10l; 10r) from the first capturing unit (3l; 3r) to an analysis unit (27) and transmitting second sig-nals concerning the captured second eye (10r; 10l) from the second capturing unit (3r; 3l) to the analysis unit (27); determining the at least one parameter of the two eyes (10l, 10r) on the basis of the transmitted first and second signals in the analysis unit (27), characterized by the following step: setting a first data rate for the first signals and a second data rate for the sec-ond signals, wherein the first and the second data rate differ from each other, and wherein the transmitting of the first signals is effected at a first data rate and the transmitting of the second signals is effected at a second data rate.
