Abstract
Systems and methods are disclosed hosting multiple visual assessments, evaluating user performance on the assessments, and providing recommendations to assess and improve user visual performance. One method includes hosting a plurality of visual assessments; presenting, via a web portal, a user interface for selecting one or more visual assessments of the hosted plurality of visual assessments; receiving, via a web portal, a request for a user to access a visual assessment, wherein the visual assessment is an assessment out of the hosted plurality of assessments; administering the visual assessment to the user; receiving user performance data associated with a user, in response to the administered visual assessment; comparing the user performance data with performance data associated with one or more other users; and generating a report of user visual performance based on the user performance data, wherein the report is accessible to the user via the web portal.
Core Innovation
The invention provides a web-based visual assessment and training/therapy platform that hosts one or more visual assessments on a hosting web platform. Each visual assessment evaluates a different aspect of visual performance or neurological function based on metrics computed from eye tracking data. A user interface of the hosting web platform presents the hosted visual assessments to a user, and the platform administers the visual assessment to the user.
In response to administering the visual assessment, the platform causes an eye tracker associated with the user to record eye tracking data associated with the user’s eye movements. The platform computes an assessment-specific metric using a high level eye movement metric derived from respective values of a plurality of different low level eye movement metrics. The low level metrics are indicative of detection of oculomotor events, including fixations, saccades, smooth pursuits, microsaccades, glissades, drifts, tremors, or square-wave jerks, and the assessment-specific metric relates to the aspect of visual performance evaluated by the visual assessment and corresponds to a user’s skill level or at least one aspect of visual performance or neurological state.
The platform compares the computed assessment-specific metric to a metric associated with one or more individuals and determines, based on the comparison or the assessment-specific metric, a user-specific conclusion on one or more of the user’s visual performance or neurological state. The platform generates an output that includes the user-specific conclusion, and the disclosed architecture supports user-accessible reports, progression tracking, and longitudinal “locker room”/team dashboards.
Claims Coverage
The partial content includes three independent claims: a computer-implemented method, a system, and a non-transitory computer-readable medium. Across all independent claims, the main inventive features comprise hosting one or more web-based visual assessments, recording eye tracking data, computing low-level eye movement metrics and an assessment-specific high-level eye movement metric, comparing to metrics associated with other individuals, and generating an output including a user-specific conclusion.
Web platform hosting of visual assessments
A computer-implemented method (or system/medium) hosting one or more visual assessments on a hosting web platform, where each assessment evaluates a different aspect of visual performance or neurological function based on metrics computed from eye tracking data.
User interface for hosted assessments and administering on request
Causing a user device to display a user interface of the hosting web platform presenting the hosted one or more visual assessments, receiving a request from the user device to access a visual assessment hosted on the hosting web platform, and administering the visual assessment to the user.
Eye tracking data recording in response to the visual assessment
Causing an eye tracker associated with the user to record eye tracking data associated with the user’s eye movements, in response to the visual assessment.
Low-level oculomotor event metrics and high-level assessment-specific metric
Computing low-level eye movement metrics indicative of detection in the eye tracking data of fixations, saccades, smooth pursuits, microsaccades, glissades, drifts, tremors, or square-wave jerks, and computing a high-level eye movement metric including an assessment-specific metric relating to the aspect of visual performance evaluated by the visual assessment, where the assessment-specific metric corresponds to one or more of a user’s skill level at a specific task or at least one aspect of the user’s visual performance or neurological state.
Comparison to individuals and user-specific conclusion output
Comparing the computed assessment-specific metric to a metric associated with one or more individuals, determining based on one or more of the comparison or the assessment-specific metric a user-specific conclusion on one or more of the user’s visual performance or neurological state, and generating an output that includes the user-specific conclusion.
Hardware and storage for executing web hosting operations
A system including a data storage device storing instructions for hosting one or more visual assessments and a processor configured to execute the instructions to perform operations including hosting the visual assessments, receiving requests, administering assessments, causing eye tracking data recording, computing low-level and high-level metrics, comparing to metrics associated with one or more individuals, determining a user-specific conclusion, and generating an output including the user-specific conclusion.
Non-transitory computer-readable medium instructions for the same operations
A non-transitory computer-readable medium comprising instructions executable by a processor to perform operations including hosting one or more visual assessments on a hosting web platform, displaying a user interface presenting the hosted assessments, receiving a request to access an assessment, administering the visual assessment, recording eye tracking data, computing low-level metrics and a high-level assessment-specific metric, comparing to metrics associated with one or more individuals, determining a user-specific conclusion, and generating an output that includes the user-specific conclusion.
Across the independent claims, the core claim coverage centers on hosting web-based visual assessments tied to eye tracking, deriving an assessment-specific high-level metric from multiple low-level oculomotor event metrics, comparing to metrics associated with other individuals, and generating an output that includes a user-specific conclusion on visual performance or neurological state.
Stated Advantages
Generates a user-specific conclusion on one or more of the user’s visual performance or neurological state based on comparison to metrics associated with one or more individuals.
Computes an assessment-specific metric that corresponds to a user’s skill level at a specific task or at least one aspect of visual performance or neurological state.
Provides an output that includes the user-specific conclusion.
Documented Applications
A training/therapy platform for improving/maintaining/rehabilitate vision or neurological function, supported by hosted visual assessments, user-accessible reports, and progression tracking.
Visual performance assessment use case based on a disclosed “Visual Performance Exam” that includes defined tests and produces example outputs/recommendations.
