Abstract:
A display managing method for managing the display of an image to a user of an optical system comprising at least a see-through displaying device (10) arranged and configured to display the image towards an eye of the user and an optical lens (20) designed to be placed in front of the eye of the user and having an optical function, the method comprises: - an optical function data providing step (S2), during which optical function data relating to the optical function of the optical lens are provided; and - a display parameter determining step (S4), during which a value of at least one display parameter is determined based at least on the optical function data.
Abstract:
A navigation method for a wearer of a see-through head mounted device, the method comprising: • - a wearer visualization parameter providing step (S1), during which at least one wearer visualization parameter is provided, • - a geo-position determining step (S2), during which the geo- position of the wearer along a route is determined, • - a geo-position comparing step during which the geo-position of the wearer determined during the geo-position determining step is compared to stored geo-positions along the route and • - a navigation visual aid function adapting step (S3) during which upon matching of the geo-position of the wearer with one of the stored geo-positions, the navigation visual aid function is adapted based on the wearer vision parameter and the geo-position of the wearer to facilitate the guiding of the wearer
Abstract:
A method implemented by computer means of determining a correcting optical function to be applied on a virtual image to be displayed to a user of an optical system (12) comprising at least: an optical lens (14) designed to be placed in front of an eye of the user and comprising at least a back face (16) having an optical design; - a see-through displaying device (20) designed and configured to display the virtual image towards the eye of the user, the virtual image being transmitted at least through the back face (16) of the optical lens defining a display area on the back face; the method comprises: - an optical design data providing step, during which optical design data relating to the optical design of the back face of the optical lens are provided; a display area data providing step, during which display area data relative to at least one parameter of the display area are provided; and a correcting optical function determining step, during which a correcting optical function is determined based at least on the optical design data and on the display area data.
Abstract:
A monitoring system for monitoring the visual behavior of a wearer of a head-mounted device, the monitoring system comprises: - a least one wearer's visual behavior sensor configured to sense at least one wearer's visual behavior data relating to the visual behavior of the wearer of the head-mounted device, - a communication unit associated with the at least one wearer's visual behavior sensor and configured to communicate said visual behavior data to a wearer information data generating unit, - a wearer information data generating unit configured to : - receive said wearer's visual behavior data, - store said wearer's visual behavior data, and - generate an wearer information data indicative of at least one of : wearer's vision or general health condition of the wearer or wearer's activity or wearer's authentication based, at least, on the evolution over time of said wearer's visual behavior data.
Abstract:
A method for evaluating the visual acuity of a person using a mobile device comprising at least a front camera and a screen, the method comprising: - a user positioning step during which the user of a mobile device positions himself in front of a mirror at a predefined distance d/2; - a mobile device positioning step during which the mobile device is positioned with the front camera of the mobile device facing the mirror; - a distance measuring step during which a distance d between the front camera of the mobile device and a virtual image of the mobile device in the mirror is measured; - a displaying step during which the screen of the mobile device displays optotypes; - an evaluation step during which the visual acuity of the user is evaluated.
Abstract:
A method for updating an index of a person, the method comprises: - an index providing step during which an index is defined as a function of at least one parameter related to the person is provided, - a parameter monitoring step during which the at least one parameter of the person is monitored over time, - an index update step during which the index of the person is updated based on the evolution over time of the at least one parameter of the person.
Abstract:
A method of controlling a head mounted see-through electro-optical device adapted to a wearer A method of controlling a head mounted electro-optical device adapted to a wearer, the method comprising: - a wearer visual profile parameter providing step, during which the value of at least one wearer parameter related to the visual profile of the wearer is provided, - an head mounted device function adapting step, during which the head mounted device function of the electro-optical device is adapted based on the value of the at least one wearer parameter.
