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.
