The present disclosure describes the clinical workflow, method, apparatus and system of an on demand artificial intelligence visual screening and visual field screening system that incorporates a display simulator cockpit frame system inside a booth, kiosk, or exam room with machine learning and telemedicine capabilities. According to various embodiments, an artificial intelligent, physical or virtual assistant may help in the screening process of the patient, and an eye doctor via telemedicine may connect to the computers in display simulator cockpit system to perform necessary medical consultations, visual examination or screenings via the display simulator cockpit frame set-up display system. Where an on demand health care provider via remote administration tool technology, remote screen sharing and remote control software control the medical equipment, provide medical consultations and medical examination to a patient from anywhere in the world via cellphone wireless networks or wifi to interconnect both systems.

Method of calibrating a computerised colour vision test and method of testing colour vision on a computer The invention relates to a method of calibrating a colour vision test for testing colour vision under given ambient lighting conditions, which colour vision test is to be displayed on a colour display (12) of a computer (10) having at least one input interface (14), characterised by displaying a calibration test on the display (12) under given ambient lighting conditions to a person with normal colour vision before starting the colour vision test, displaying within at least one measuring region (31) of the display (12) a colour determination task requiring user input as a part of the calibration test, reading the user input through at least one input interface (14) of the computer (10), evaluating the read user input and determining as a result of the evaluation a display error resulting from a combination of a colour reproduction capability of the display (12) and an effect of the ambient lighting conditions on colour vision, and determining a modification to the colour vision test from the display error that corrects the colour vision test with respect to the display error. The invention further relates to a method of testing colour vision using the calibration method, as well as to a computer and computer program configured for performing such methods. The invention further relates to a colour discrimination test, to a colour identification test and to a combination of the two tests.

A waveguide apparatus includes a planar waveguide and at least one optical diffraction element (DOE) that provides a plurality of optical paths between an exterior and interior of the planar waveguide. A phase profile of the DOE may combine a linear diffraction grating with a circular lens, to shape a wave front and produce beams with desired focus. Waveguide apparati may be assembled to create multiple focal planes. The DOE may have a low diffraction efficiency, and planar waveguides may be transparent when viewed normally, allowing passage of light from an ambient environment (e.g., real world) useful in AR systems. Light may be returned for temporally sequentially passes through the planar waveguide. The DOE(s) may be fixed or may have dynamically adjustable characteristics. An optical coupler system may couple images to the waveguide apparatus from a projector, for instance a biaxially scanning cantilevered optical fiber tip.

A method for generating an indicator or biomarker of colour perception in a mammalian subject, where the method may include submitting the mammalian subject to a multicoloured dynamic stimulus comprising displaying, on a display device. The method may include controlling a change over time of at least one of the two colours of the multicolour pattern when displaying the dynamic multicolour stimulus, to vary the displayed luminance of this colour (usually several times). The method may include acquiring, by using an image acquisition device, an oscillatory response of a pupil of the mammalian subject. The method may include generating, from the acquired response, a signal representative of the power of the pupil's oscillatory response as a function of the change over time of at least one of the two colours when displaying the dynamic multicoloured stimulus.

Systems and methods for determining whether to enable color blind accessibility settings within the course of a user interactive narrative are described herein. Virtual color blindness indication objects containing colors that are visibly distinguishable within a single dichromatic visual spectrum can be utilized in objectives to determine a user's dichromatic visual deficiency type.

One embodiment is directed to a system comprising a head-mounted member removably coupleable to the user's head; one or more electromagnetic radiation emitters coupled to the head-mounted member and configured to emit light with at least two different wavelengths toward at least one of the eyes of the user; one or more electromagnetic radiation detectors coupled to the head-mounted member and configured to receive light reflected after encountering at least one blood vessel of the eye; and a controller operatively coupled to the one or more electromagnetic radiation emitters and detectors and configured to cause the one or more electromagnetic radiation emitters to emit pulses of light while also causing the one or more electromagnetic radiation detectors to detect levels of light absorption related to the emitted pulses of light, and to produce an output that is proportional to an oxygen saturation level in the blood vessel.
