    摘要: One aspect of the disclosure includes a method to assess vision function. In one embodiment, the method comprises providing a sequence of test images on a display (106) to a test subject (102) during a stimulus interval and providing a response pattern image for each of the sequence of test images during a response interval after the stimulus interval. Each of the sequence of test images includes multiple stimulus patterns (304, 306) arranged around a fixation target (302). The response pattern image includes multiple response targets (320), each of which corresponds to a location of each of the multiple stimulus patterns (304, 306). One (304) of the multiple stimulus patterns (304, 306) differs. An assessment of a vision function of the test subject (102) is based on a selection by the test subject of one of the multiple response targets (320) that the test subject indicates corresponds to a location of the multiple stimulus pattern that differs (304). A corresponding vision testing system (100) is disclosed as well.

    摘要: Cognitive function testing. At least some of example embodiments are methods including performing a cognitive function test on a patient without calibrating pupil position of the patient. The performing may include: causing a visual cue on a computer screen in front of the patient to move in a predetermined pattern; reading frames from an eye camera that captures images of an eye of the patient while the visual cue moves on the computer screen and the patient visually tracks the visual cue; determining pupil position within the frames; correcting offsets between the stimulus data and the pupil position data; translating the pupil position data from a coordinate space of the eye camera to a coordinate space of the stimulus data; and generating a test score being the cumulative distance between the stimulus data and pupil position data for each corresponding point in time.

    摘要: This invention relates to a method for providing markers for evaluating and/or practising the visual field recognizable by an eye, and/or eyes, and/or visual system of a person. The method relies on the reporting of the person of identifications of fixation objects only identifiable when the eye or eyes of the person are accurately fixated on the fixation object. Accordingly active monitoring of a saccade, if a saccade triggering stimulus is employed; or smooth pursuit, if smooth pursuit triggering stimulus is employed, of the eye of the person is not needed for determining whereto to eye or eyes are fixated. The present invention also relates to the use of a system employing the method of the invention. The present invention further relates to a system for the method of the invention and a software product for the system.
