Method and a system for eye tracking

A system for eye tracking, comprising:

• an image capturing device configured to capture a sequence of digital images of an eye;
• an image processing unit configured to receive data including said sequence of images from the image capturing device and determine a sequence of positions of the eye, each position being indicative of a gaze direction;
• a biosignal acquisition unit configured to acquire biosignal data representing an activity of the eye;
• a biosignal processing unit configured to receive the biosignal data and detect closing of the eye based on the acquired biosignal data;
• and
• a control unit configured to, in response to the biosignal processing unit detecting closing of the eye, outputting a control signal for pausing at least one of:
• an image capture operation of the image capturing device, an image processing operation of the image processing unit, and a transfer of data including said sequence of images between the image processing unit and the image capturing device.
