The invention relates to a method for operating an eye tracking device () comprising as components an imaging device (), an illumination unit () and a processing unit () and further at least two adjustment parameters (P), for adjusting the components (). The eye tracking device () comprises a control unit () for controlling the adjustment parameters (P). According to the method an image () of an eye is captured, a condition () with respect to a quality related to eye tracking or a power consumption of the components () is set, a predefined correlation () correlating the adjustment parameters (P) to the quality and the power consumption is provided and the control unit () controls the adjustment parameters (P) according to the predefined correlation (), so that the element, with respect to which the condition () was set, fulfils the condition ().

Method for operating an eye tracking device and eye tracking device for providing an active power management

The invention relates to an eye tracking device and a method for operating an eye tracking device () comprising an imaging device (), a plurality of light sources (), a processing unit and a control unit. The imaging device () captures a first image () while at least one of the light sources () emits light. If at least one first reflection (-) is detected, a position in the first image () of the at least one first reflection (-) is determined, the first reflection (-) is categorized on the basis of the position in the first image () and if the first image () does not fulfill a predefined quality criterion, the plurality of light sources () is controlled in dependence of the categorization by changing the light intensity of at least one light source ().
