The present disclosure relates to a device for visual field testing 11, which maps eye function of a test subject, the device comprising a display unit 17 displaying stimuli 23 to the test subject, and an eye tracking unit 19 detecting eye motions in response to the displayed stimuli. The display unit 17 displays at least a first 23 and a second 25 peripheral stimulus at different sectors in relation to a point of fixation 27 at the same time and the eye tracking unit determines which of the first and second stimulus is first gazed upon by the test subject. This allows different parts of the retina to compete with regards to retinal sensitivity and allows for a precise and efficient visual field testing.

A system can include a non-transitory memory to store machine readable instructions and data, and a processor to access the non-transitory memory and execute the machine-readable instructions. The machine-readable instruction can include a global module that can be programmed to generate a visual field map (VFM) model that can include a set of visual function map parameters for an entire visual field for a subject. The global module can be programmed to update the set of visual function map parameters corresponding to updating a shape of the VFM based on subject response data generated during each administration of a vision test to a subject.

The present disclosure relates to systems and methods for characterizing a behavior change of a process. A behavior model that can include a set of behavior parameters can be generated based on behavior data characterizing a prior behavior change of a process. A stimulus parameter for a performance test can be determined based on the set of behavior parameters. An application of the performance test to the process can be controlled based on the stimulus parameter to provide a measure of behavior change of the process. Response data characterizing one or more responses associated with the process during the performance test can be received. The set of behavior parameters can be updated based on the response data to update the behavior model characterizing the behavior change of the process. In some examples, the behavior model can be evaluated to improve or affect a future behavior performance of the process.

A method for performing a full-field stimulus threshold (FST) test on a test subject, the method comprising: delivering at least one visual stimulus to 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, wherein the intensity of the flash of light is adjusted over the duration of the flash of light; obtaining at least one response from the test subject, wherein the at least one response corresponds to whether the test subject perceived the at least one visual stimulus; and determining the lowest intensity of light that the test subject is able to perceive based on the at least one response from the test subject.

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.

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.

Disclosed is a binocular optoelectronic device wearable by a user for measuring a light sensitivity threshold of the user, including: a diffuser configured to face eyes of the user; at least one light source for emitting light toward the diffuser. The diffuser includes predetermined parameters allowing to provide a quasi-homogeneous light diffusion to at least one eye of the user from light emitted by the at least one light source.

A method of retrieving data comprises receiving a user input in the form of a command, determining that the user input is a gesture, sending a request to a cloud server based on the determined gesture, receiving data from a knowledge base connected to the cloud server based on the request, and displaying virtual content at the user device based on the received data.
