    摘要: A method of analyzing a visual field of an individual comprises the following steps:—measuring (S4) a first visual field (VF1) of said individual for a first set of oculo-postural parameters of said individual when said individual performs a first task;—measuring (S6) at least one additional visual field (VFi) of said individual for one additional set of said oculo-postural parameters of said individual when said individual performs an additional task;—determining (S8) a functional visual space based on said first visual field (VF1) and said at least one additional visual field (VFi), said functional visual space being an envelope of said first visual field and said at least one additional visual field. The additional task differs from said first task and/or said additional set of oculo-postural parameters differs from said first set of oculo-postural parameters. A corresponding ophthalmic lens is also proposed.

    摘要: A method for determining an optical design criterion for designing an optical lens adapted to a sport practice, the method including: defining an evaluation axis for evaluating sensory/motor/cognitive requirement of a sport practice, for each of a plurality of sports; attributing a score to the sport practice on each evaluation axis; determining clusters of sports in which practices have similar score; determining at least one visual need corresponding to each cluster of sports; determining, for each cluster, at least one optical design criterion as a function of the associated visual need; and storing in a memory a record for each cluster, along with each optical design criterion associated with the cluster.

    摘要: A system simulating a decisional process in a mammal brain about characteristics of motions related to body gestures of a visually observed body through a simulated visual path is provided. The system includes an interface toward simulated neuronal structures, the interface at least converting luminous information of the observed body to an optic flow data stream conveying information related to the visually observed body and that can be processed in the simulated neuronal structures, the system being a feed-forward system and comprising hierarchically from the visual observation to the decision: the simulated visual path and its interface, a simulated local motion direction detection neuronal structure for the detection of motion directions with receptive fields, a simulated opponent motions detection neuronal structure, a simulated complex patterns detection neuronal structure, and a simulated motion pattern detection neuronal structure.
