20140148707 | METHOD FOR ESTIMATING A REFERENCE POSTURE - The invention relates to a method for estimating a reference posture of a subject with a view to taking measurements in order to determine the parameters for manufacturing a vision correction device, including, for a plurality of instances in which the head reaches a target reference posture from at least one deviated posture, the steps of: measuring the actual reference posture to thus obtain a plurality of sets of actual reference posture data, and storing said sets of data in a memory; and processing said sets of actual reference posture data using a digital processing unit in order to obtain an optimal reference posture. | 05-29-2014 |
20090214086 | Vision Correction Aid System - 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 analyze 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. | 08-27-2009 |
