| 摘要 |
The invention relates to automatic eye tracking, wherein at least one imaging device (150) registers sequential image data (DEYE) representing at least one eye (181; 182) of a subject (180). A processing unit (170) receives the image data (DEYE), and based thereon, produces a position estimate of the at least one eye (181; 182). The processing unit (170) also produces a control signal (C|LS_)> which is received by at least one light source (140). The at least one light source (140), in turn, emits at least one light beam (L) being variable, such that a spatial location of an illumination area (A|LL) towards which at least one light beam (L) is directed depends on the characteristics of the control signal (CI LL). Specifically, the processing unit (170) produces the control signal (C|LL) so that the illumination area (A|LL) includes a position estimate of the at least one eye (181; 182). |
