Abstract
Some systems and methods disclosed herein facilitate calibration of a head-mounted display while a visual test is performed. One mechanism of facilitating calibration involves detecting, as a visual test is being performed, that the user's eyes moved in the direction of a displayed stimulus but have not stopped at the point of where the stimulus is displayed, and instead stopped at a different point (e.g., a threshold distance away from the stimulus). Based on that detection, the system may determine that the user has seen the stimulus and that calibration of the sensors is needed. The system may then record that the user has seen the stimulus and perform sensor calibration before displaying the next stimulus.
Core Innovation
The invention relates to visual field testing using a user device that presents a stimulus at a visual field location and obtains feedback via one or more inward directed sensors. During the visual field test, first feedback data related to the first stimulus presented at the first visual field location is obtained, and based on the first feedback data indicating that an eye of a user failed to fixate on the first visual field location, the system performs a calibration of the one or more inward directed sensors.
The calibration is performed by adjusting a configuration of the one or more inward directed sensors such that a location that the user fixated on matches the first visual field location. The system stores, during the visual field test, based on the first feedback data, a first indication that the user has seen the first stimulus.
In some implementations, the invention determines whether the stimulus was seen based on gaze location in relation to the first visual field location using a threshold distance or threshold movement toward the visual field location. After calibration, the invention can cause a second stimulus to be presented for a second visual field location and obtain second feedback data, store a second indication that the user has seen the second stimulus, and refrain from performing further calibration in response to detecting fixation for the second location.
Claims Coverage
The provided set includes three independent claims: clm-00001, clm-00011, and clm-00016. Across these independent claims, the inventive subject matter centers on presenting stimuli during a visual field test, obtaining inward-directed sensor feedback, calibrating sensor configuration when feedback indicates a fixation failure at a target visual-field location, and storing indications that the user has seen the stimulus.
Inward-directed sensor calibration triggered by fixation failure during visual field testing
Causing, during a visual field test, a first stimulus to be presented on a user device at a first visual field location; obtaining, during the visual field test, via one or more inward directed sensors of the user device, first feedback data related to the first stimulus presented at the first visual field location; performing, during the visual field test, a calibration of the one or more inward directed sensors of the user device based on the first feedback data indicating that an eye of a user failed to fixate on the first visual field location; wherein performing the calibration comprises adjusting a configuration of the one or more inward directed sensors of the user device such that a location that the user fixated on matches the first visual field location
Storing seen-stimulus indications based on inward-directed sensor feedback
Storing, during the visual field test, based on the first feedback data, a first indication that the user has seen the first stimulus
System for visual field testing with inward-directed sensor calibration and seen-stimulus indication
A system comprising one or more processors and non-transitory media storing instructions that, when executed by the one or more processors, cause operations comprising causing, during a visual field test, a first stimulus to be presented on a user device for a first visual field location; obtaining, during the visual field test, via one or more inward directed sensors of the user device, first feedback data related to the first stimulus presented for the first visual field location; performing, during the visual field test, a calibration of the one or more inward directed sensors of the user device based on the first feedback data indicating that an eye of a user failed to fixate on the first visual field location; wherein performing the calibration comprises adjusting a configuration of the one or more inward directed sensors of the user device such that a location that the user fixated on matches the first visual field location; and storing, during the visual field test, based on the first feedback data, a first indication that the user has seen the first stimulus
Method for calibrating a user device during a visual field test and storing seen-stimulus indications
Causing, during a visual field test, a first stimulus to be presented on a user device for a first visual field location; obtaining, during the visual field test, via one or more inward directed sensors of the user device, first feedback data related to the first stimulus presented for the first visual field location; performing, during the visual field test, a calibration of the user device based on the first feedback data indicating that an eye of a user failed to fixate on the first visual field location; wherein performing the calibration comprises adjusting a configuration of the one or more inward directed sensors of the user device such that a location that the user fixated on matches the first visual field location; and storing, during the visual field test, based on the first feedback data, a first indication that the user has seen the first stimulus
Across clm-00001, clm-00011, and clm-00016, the independent claims share the same core flow: present a first stimulus at a first visual field location, obtain first feedback data via inward directed sensors, calibrate the inward directed sensor configuration when the feedback indicates failed fixation at the first visual field location, and store an indication that the user has seen the first stimulus. Dependent claim refinements in the provided materials additionally include head-mounted display embodiments, specific fixation-failure characterizations, quantitative threshold-based determination that the stimulus was seen, and a second stimulus flow that can omit further calibration after fixation is detected.
