VISUAL FIELD MAP EXPANSION
A method includes obtaining spatial information indicating positions of electronic displays relative to a wearable device and selecting a first display location on an electronic display other than a wearable display of the wearable device based on the spatial information indicating that the first display location on the electronic display corresponds to a first field location of a visual field. The method further includes selecting a second display location on the wearable device based on the spatial information indicating that the second display location on the wearable display corresponds to a second field location of the visual field. The method further includes causing presentation of (i) a first stimulus at the first display location on the electronic display and (ii) a second stimulus at the second display location on the wearable device and generating ocular anomaly information based on feedback information related to the presented stimuli.
Apparatus and method for capturing a visual field of a person having a scotoma
A method and an apparatus for capturing a visual field of a person having a scotoma, in particular a central scotoma, are disclosed. The method includes continuously capturing the eye alignment of the person with a capturing unit, sampling the visual field of the person point-by-point to determine points suitable and not suitable for sight in the visual field of the person, finding the scotoma as a region with a multiplicity of points not suitable for sight, calculating an outer boundary line of the scotoma, calculating an outer enveloping curve, which surrounds the outer boundary line of the scotoma at a predetermined distance, and displaying the outer enveloping curve on a display unit. The enveloping curve is perceivable by the person on the display unit as a frame of the scotoma.
Through Focus Retinal Image Capturing
An apparatus for producing a non-mydriatic fundus image is disclosed. The apparatus can include a processor and memory, as well as an illumination component and a camera with a variable focus lens. The apparatus can be configured to adjust the focus of the lens to a plurality of different diopter ranges and capture at least one image at each of the plurality of different diopter ranges. Using the captured images, three-dimensional maps of the fundus may be generated. Three-dimensional maps of the fundus may be used to screen or diagnose various diseases.
Ophthalmic device
An ophthalmic device comprising a light source to emit fixation target light, and a reflecting face to reflect scanning light emitted by an emission section and scan the scanning light in a specific direction by changing orientation, the emission section being a scanning light source different to the light source. A concave mirror face is disposed so scanning light reflected by the reflecting face is incident on a subject's eye ocular fundus when the eye is at the concave mirror's focal point, and is arranged such that, when the eye is at the concave mirror's focal point, and when the light source emits fixation target light, that light and scanning light are simultaneously incident on the ocular fundus via different optical paths propagating via the concave mirror face and focal point, the target fixation light following a predetermined optical path for fixing the subject's eye gaze.
System and method of utilizing computer-aided optics
The disclosure provides a system that may provide a virtual object at a first virtual distance to an eye of a patient; may provide a first light wave to the eye; may receive a first perturbed light wave, based at least on the first light wave, from the eye; may determine first optical corrections based at least on the first perturbed light; may provide the virtual object at a second virtual distance to the eye; after providing the virtual object at the second virtual distance, may provide a second light wave to the eye; may receive a second perturbed light wave, based at least on the second light wave, from the eye; may determine second optical corrections based at least on the second perturbed light; and may determine a corrective optical solution for the eye based at least on the first optical corrections and the second optical corrections.
Methods and Systems for Obtaining, Analyzing, and Generating Vision Performance Data and Modifying Media Based on the Vision Performance Data
The present specification describes methods and systems for modifying a media, such as Virtual Reality, Augmented Reality, or Mixed Reality (VR/AR/MxR) media based on a vision profile and a target application. In embodiments of the specification, a Sensory Data Exchange (SDE) is created that enables identification of various vision profiles for users and user groups. The SDE may be utilized to modify one or more media in accordance with each type of user and/or user group.
Correcting systematic calibration errors in eye tracking data
Systems and methods are provided for post-hoc correction of calibration errors in eye tracking data, which take into consideration calibration errors that result from changes in user position during a user session in which the user's fixations on a display screen are captured and recorded by an eye tracking system, and which take into consideration errors that occur when the user looks away from a displayed target item before selecting the target item.
SYSTEMS AND METHODS FOR EVALUATING HUMAN EYE TRACKING
Systems and methods are disclosed for evaluating human eye tracking. One method includes receiving data representing the location of and/or information tracked by an individual's eye or eyes before, during, or after the individual performs a task; identifying a temporal phase or a biomechanical phase of the task performed by the individual; identifying a visual cue in the identified temporal phase or biomechanical phase; and scoring the tracking of the individual's eye or eyes by comparing the data to the visual cue.
Method, Software and Apparatus for Testing a Patient's Visual Field
A method for testing a patient's (2) visual field using testing apparatus. A fixation target is provided on a display (3) at a known target position and the patient's (2) direction of gaze is tracked using an eye tracker to determine the patient's point of regard. A marker (5) is provided on the display (3) indicating the patient's (2) point of regard, where the marker (5) moves with movement of the patient's (2) point of regard. It is detected when the marker (5) is moved to the fixation target and a new target is then provided on the display at a further known target position. The new target is recorded as detected if the marker (5) is moved to the new target, with the new target then becoming the fixation target. The steps are repeated for further new targets for determining the patient's (2) visual field based on the positions of the new targets that have been detected.
Evaluation device, evaluation method, and non-transitory storage medium
An evaluation device includes: a display screen configured to displays images; a gaze point detection unit configured to detect a position of a gaze point of an examinee who observes the display screen; a display controller configured to display an indicator at an offset position having a predetermined relative positional relationship with the gaze point on the display screen based on a detection result of the position of the gaze point; an arithmetic unit configured to determine whether the examinee has recognized the indicator; and an evaluation unit configured to evaluate a visual function of the examinee based on a determination result from the arithmetic unit, wherein the arithmetic unit is further configured to determine that the examinee has recognized the indicator when the gaze point moves toward the indicator and thus the offset position is located outside the display screen.
