A method of rendering virtual content comprises capturing an image of a field of view of a user, extracting a set of map points based on the captured image, recognizing an object based on the extracted set of map points, retrieving semantic data associated with the recognized object and attaching the semantic data to object data associated with the recognized object, and inserting the recognized object data and the semantic data attached thereto into a virtual world model such that virtual content, when rendered at a user device of the user, is displayed in relation to the recognized object.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

A method identifies at least one malfunctioning nozzle in a digital printing press, the digital printing press including a plurality of nozzles. The method includes printing a design on a substrate, acquiring at least one image of the printed design and identifying at least one artifact in the acquired image. The method further includes identifying the malfunctioning nozzle and classifying the at least one malfunctioning nozzle according to the at least one of the acquired image of the printed design, at least a portion of a nozzle pattern and at least a portion of a uniformity pattern.

Methods, systems, and devices are provided for measuring dark adaptation of one or both eyes of a patient, and more particularly, for measuring dark adaptation with a mobile device application. An exemplary method includes exposing an eye of a patient to a light source to bleach a retinal location of the eye, displaying on a mobile device a figure with a luminance and waiting until the patient communicates with the mobile device to acknowledge that the patient can see the figure, measuring and recording a level of the luminance and a time period between first displaying the figure and the patient communicating with the mobile device, continuing to display additional figures with decreasing luminance one at a time, and determining by a processor dark adaptation measurements of the patent based on the measured and recorded luminance and time periods.

An ophthalmologic apparatus includes an objective measurement optical system that measures an objective refraction characteristic of a subject eye and a control portion that performs total control including control of the objective measurement optical system, wherein the control portion analyzes a characteristic amount of a ring image obtained by measuring the objective refraction characteristic of the subject eye to feedback to a subjective examination content of the subject eye according to an analysis result of the characteristic amount of the ring image.

A method for performing a pupillary stimulus threshold test on at least one eye of a test subject, the method comprising: delivering at least one visual stimulus to the at least one eye of the test subject, wherein the least one visual stimulus comprises a flash of light having an intensity and a duration; obtaining at least one pupillary response from the at least one eye of the test subject, wherein the at least one pupillary response corresponds to whether or not the test subject's pupil contracted in response to the at least one visual stimulus; and determining the lowest intensity of light that causes the test subject's pupil to contract based on the at least one pupillary response from the test subject.

The invention provides a method for determining at least one filter for a transparent support, the method comprising the following steps: determining a quantity representative of a light sensitivity threshold of the user; determining, for each light environment among a group of light environments, an index representative of the level of protection required by the user; determining a score for each light environment among the group of light environments (40) and for each filter among a group of filters, said score being representative of the capacity of the filter to reach the level of protection required by the user, determining at least one filter among the group of filters based on the scores of said at least one filter in a plurality of light environments (40) among the group of light environments.
