The invention concerns a device for measuring the position of the fixing point (P') of an eye on a video screen (19) comprising: a mobile support (10) positioned close to the eye and on which first illumination means (12) and a video camera (11) are fixed so as to embody images of the eye, and a fixed support (17) distant from the eye and on which the video screen orientated opposite the eye and a plurality of luminous sources illuminating the eye in alternative with the first illumination means are positioned and disposed around the video screen so as to create on the eye corneal reflections and means (20) for treating the images obtained from the eye. The invention also concerns an eye illumination method in which the eye is illuminated by flashes each emitted at the end of each taking of images, as well as an application of the device for displaying on the video screen images which change according to the movements of the eye wherein a high resolution zone (Z) is defined around the fixing point (P') and for moving this zone according to the movements of the eye. Application for the medical sphere, ergonomics and interactive data processing.
Device for measuring the position of the first mobile support (10) integral with the head of the subject and positioned close to the eye and on which secured are first means (12) for illuminating the eye and video means (11) to embody images of the eye, and a support means having a fixed support (17) distant from the eye and on which positioned are firstly the target (19) orientated so as to be approximately opposite the eye, and secondly second eye illumination means (18) able to create on the eye corneal reflections (R1, R2, R3, R4).
A method for taking images of the eye comprising the steps of:
