Abstract
In some embodiments, a fixation point may be adjusted for a visual test presentation after a first stimulus is displayed at a first interface location on a user interface for a user. While the fixation point remains at the first interface location, one or more stimuli may be displayed on the user interface. While the fixation point remains at the first interface location, and after the display of the one or more stimuli on the user interface, a second stimulus may be displayed at a second interface location on the user interface. Vision defect information associated with the user may be generated based on feedback information indicating feedback related to the first stimulus, feedback related to the one or more stimuli, or feedback related to the second stimulus.
Claims20
A system for facilitating vision defect information generation, the system comprising:
- one or more processors and one or more non-transitory media storing instructions that, when executed by the one or more processors, cause operations comprising:
- adjusting, during a visual test presentation, a fixation point for the visual test presentation after a first stimulus is displayed at a first interface location on a user interface of a wearable device of a user, wherein the first interface location correspond to a first visual field location of a test set, and wherein, before the adjustment of the fixation point, the first interface location is at least as far from the fixation point as all other interface locations of the user interface that correspond to visual field locations of the test set;
- causing, during the visual test presentation, a second stimulus to be displayed at a second interface location on the user interface after the adjustment of the fixation point;
- obtaining, during the visual test presentation, feedback information indicating feedback related to the first stimulus and feedback related to the second stimulus, the feedback related to the first or second stimulus indicating a response of the user or lack of response of the user to the first or second stimulus;
- and
- generating vision defect information associated with the user based on the feedback information.
A method being implemented by one or more processors executing computer program instructions that, when executed, perform the method, the method comprising:
- adjusting, during a visual test presentation, a fixation point for the visual test presentation after a first stimulus is displayed at a first interface location on a user interface of a wearable device of a user;
- causing, during the visual test presentation, while the fixation point remains at the first interface location, one or more stimuli to be displayed on the user interface at one or more interface locations other than the first interface location or a second interface location;
- causing, during the visual test presentation, a second stimulus to be displayed at the second interface location on the user interface (i) while the fixation point remains at the first interface location and (ii) after the display of the one or more stimuli on the user interface;
- and
- generating vision defect information associated with the user based on feedback information indicating feedback related to the first stimulus, feedback related to the one or more stimuli, or feedback related to the second stimulus.
One or more non-transitory computer-readable media comprising instructions that, when executed by one or more processors, cause operations comprising:
- adjusting, during a visual test presentation, a fixation point for the visual test presentation after a first stimulus is displayed at a first interface location on a user interface of a wearable device of a user;
- causing, during the visual test presentation, while the fixation point remains at the first interface location, one or more stimuli to be displayed on the user interface;
- causing, during the visual test presentation, a second stimulus to be displayed at a second interface location on the user interface (i) while the fixation point remains at the first interface location and (ii) after the display of the one or more stimuli on the user interface;
- and
- generating vision defect information associated with the user based on feedback information indicating feedback related to the first stimulus, feedback related to the one or more stimuli, or feedback related to the second stimulus.
