A method for determining a position variation of an eyewear equipment worn by a wearer includes obtaining reference data representing a reference position of an eyewear equipment worn by the wearer, the eyewear equipment including at least one ophthalmic lens and a frame on which the at least one ophthalmic lens is mounted, determining at least one reference position parameter indicative of a reference position of the eyewear equipment on the face of the wearer based on the reference data, obtaining current data representing a current position of the eyewear equipment worn by the wearer, determining at least one current position parameter indicative of a current position of the eyewear equipment in front of the eyes of the wearer based on the current data, and comparing the reference and current positions parameters to determine a position variation of the eyewear equipment worn by the wearer.

Position variations of the lenses of an eyewear equipment

A method for determining a component of an ophthalmic equipment, the method including acquiring a set of parameter values relating to the given wearer, processing the acquired set of parameter values to infer a group, the given wearer belonging to the inferred group and the inferred group belongs to a plurality of pre-established groups, the pre-established groups being elaborated based on respective sets of parameter values of a plurality of reference wearers. The method further including determining, based on the inferred group, at least a feature enabling to determine a component of an ophthalmic equipment of the given wearer, and determining a component of an ophthalmic equipment to be used by the wearer based on the at least a determined feature, each set of parameters values of the plurality of reference wearers including parameter values belonging to at least two distinct categories.

Method for determining a component of an ophthalmic equipment and associated system

Method for determining an ophthalmic equipment which is adapted to the characteristics of at least a given wearer, the method being implemented by a processor, the method comprising: —providing access to digital content of the wearer (S), —analyzing the digital content of the wearer so as to extract wearer data (S), —processing the wearer data so as to obtain a set of characteristics (S), the set of characteristics comprising at least one category and at least one associated score, and —determining at least one component of an ophthalmic equipment based on the obtained set of characteristics (S).

This method for predicting at least one eye gazing parameter of a person wearing visual equipment includes steps of: measuring data of at least two individuals wearing visual equipment, such data including at least head motion parameters and eye gazing parameters of the individuals; measuring head motion parameters of the person in real-life conditions; comparing the head motion parameters of the person with the head motion parameters of the at least two individuals; and predicting the at least one eye gazing parameter of the person at least on the basis of the results of the comparing step and of the eye gazing parameters of the at least two individuals.

Disclosed is a method implemented with a head-mounted device for identifying a distinct device within a given range distance of the head-mounted device, the head-mounted device includes a receiver adapted to receive wireless signals and a memory adapted to store data. The method includes: a tag data receiving step during which tag data identifying at least one electronic wireless tag placed on the distinct device are received by the receiver of the head-mounted device; a storing step during which the stored data including the tag data are stored in the memory of the head-mounted device; and an identification step during which the device is identified based on the stored data.
