摘要 |
A method of determining the position or attitude of an eye, including the steps of directing a plurality of eye-safe light beam components onto the eye, said components defining an area of incidence on the eye substantially larger than the pupil; receiving an image of light thereafter reflected by the eye; analyzing the image by identifying which of the light beam components produces a bright eye reflection in said image; and determining the position or attitude of the eye by further analysing the image on the basis of said identification. |
