Abstract: According to an aspect of the present inventive concept there is provided a method for eye tracking, comprising: capturing a sequence of digital images of an eye of a user; outputting data including said sequence of images to an image processing unit; processing said data by the image processing unit to determine a sequence of positions of the eye, each position being indicative of a gaze direction, acquiring biosignal data representing an activity of the eye; and in response to detecting closing of the eye based on the acquired biosignal data, pausing at least one of said capturing, said outputting and said processing. A system for implementing the method is also disclosed.

Abstract: A method for monitoring an eye position, comprises: capturing (202) a sequence of digital images of an eye; acquiring (204) a sequence of biosignal data representing eye movements; determining (206) a set of reference eye positions based on the sequence of digital images; and determining (208) a set of intermediate eye positions based on said set of reference eye positions and said sequence of biosignal data, said set of intermediate eye positions representing eye positions relative to said set of reference eye positions, wherein the set of intermediate eye positions represents eye positions between consecutive pairs of images of said sequence of digital images.
