Abstract (en)

[origin: WO2007045694A2] The invention relates to a system that is used to aid in determining vision correction. The inventive system is characterised in that it combines: a camera which can take animated images of the subject's face along a determined visual axis; a display device which represents the images taken by the camera; an accessory which can be worn by the subject in a fixed manner on the head and which bears a plurality of visual reference marks; means which form the visual reference mark(s) and which can cover at least two determined regions in relation to the camera; and image-analysis means which can analyse the position of the visual reference marks in the images taken by the camera and deduce therefrom the position and spatial orientation of the accessory and, consequently, the subject's head when the subject is looking at a visual target, in order to ascertain information relating to the visual behaviour of the subject when the subject moves the direction in which he/she is looking.
