    摘要: Examples of assessing vergence capability of an individual are described. In an example, a first random dot stereogram is generated. The first random dot stereogram includes a first random arrangement of dots and a first sub-portion positioned against the first random dot stereogram. Thereafter, an input from an individual, identifying the position of the first sub-portion against the first random dot stereogram may be received. In response to receiving the input, a second random dot stereogram comprising a second sub-portion positioned against the second random dot stereogram, is generated. The second random dot stereogram comprises a second random arrangement which is different from the first random arrangement of dots in the preceding first random dot stereogram. In response to the second random dot stereogram, another input to identify position of the second sub-portion against the second random dot stereogram is received.

    摘要: The present disclosure is directed to systems and methods for measuring pupillary responses to visible light stimuli. An exemplary system provides a display and a camera on the same side of a device; the display provides a visible light stimulus to illuminate a user's face and cause a pupillary reflex. A visible light or infrared camera thereafter receives image data of the pupillary light reflex. In some examples, an ambient light sensor and infrared measurement systems allow for performing pupillary light reflex assessments in low lighting conditions.

    摘要: Embodiments related to analyzing brain activity of a subject to identify signs associated with binocular rivalry. Sensed electrical activity of a subject's brain is received over a time period while the subject is exposed to a visual stimulus. The sensed electrical activity comprises a first frequency band associated with a first frequency of a first image presented to the subject's left eye, a second frequency band associated with a second frequency of a second image presented to the subject's right eye. A set of events in the time period is determined based on the frequency bands, wherein an event is associated with a change from a previous perceptual event to a new perceptual event. A metric for the subject is determined based on the set of events. The metric is analyzed to determine whether the subject exhibits signs associated with a condition that is associated with binocular rivalry.
