Abstract
Systems and methods are disclosed for assessing user physiology via eye tracking data. One method includes determining a plurality of visual assessments; determining, for each assessment of the plurality of visual assessments, a data schema, where at least one data schema is associated with more than one assessment of the plurality of visual assessments; storing the determined data schema; receiving user eye tracking data associated with a selected visual assessment of the plurality of visual assessments; determining, of the stored data schema(a), a selected stored data schema associated with the selected visual assessment; categorizing the received eye tracking data based on the selected stored data schema; computing quantitative data based on the categorized data and data related to one or more individuals other than the user; generating a report of user physiological function based on the computed quantitative data; and outputting the report to a web portal.
Core Innovation
The invention provides a method and system for assessing human physiology and performance via eye tracking data by determining a plurality of visual assessments, where each visual assessment comprises an eye tracking exercise applicable to evaluate at least one of a plurality of physiological functions. The plurality of physiological functions are across a plurality of categories including reading ability, physical performance vision, and neurological function. User eye tracking data is associated with an individual's performance of the physiological function corresponding to a selected visual assessment.
For each visual assessment, the invention determines and stores a data schema, where at least one data schema is associated with more than one visual assessment. The method determines and accesses a selected stored data schema corresponding to the selected visual assessment, and categorizes the received user eye tracking data based on the determined and accessed selected stored data schema. Categorized eye tracking data related to one or more individuals other than the individual is retrieved, where the categorized eye tracking data is categorized based on the stored data schema.
The invention computes quantitative data based on the categorized user eye tracking data and the retrieved categorized eye tracking data related to one or more individuals other than the individual. An electronic interface is generated and displayed comprising a report of the physiological function of the individual corresponding to the selected visual assessment based on the computed quantitative data. The disclosure further describes performance metrics and data quality filtering, and enables comparison using categorized cross-individual data to generate report outputs for user and specialist review.
Claims Coverage
The independent claims cover three implementations of the same core concept: a method, a system, and a non-transitory computer readable medium. Across these claims, the core inventive features are centered on schema-based categorization of eye tracking data, cross-individual retrieval, quantitative computation, and generation/display of a physiological-function report via an electronic interface.
Schema-based eye tracking data categorization for selected visual assessments
determining and storing a data schema for each visual assessment of the plurality of visual assessments, where at least one data schema is associated with more than one visual assessment of the plurality of visual assessments; determining and accessing, of the stored data schema, a selected stored data schema corresponding to the selected visual assessment; categorizing the received user eye tracking data based on the determined and accessed selected stored data schema
Cross-individual retrieval of categorized eye tracking data
retrieving categorized eye tracking data related to one or more individuals other than the individual, the categorized eye tracking data being categorized based on the stored data schema
Quantitative computation using both user and cross-individual categorized data
computing quantitative data based on the categorized user eye tracking data and the retrieved categorized eye tracking data related to one or more individuals other than the individual
Electronic interface report generation based on computed quantitative data
generating and displaying an electronic interface comprising a report of the physiological function of the individual, corresponding to the selected visual assessment, based on the computed quantitative data
Physiological-function categories spanning reading ability, physical performance vision, and neurological function
determining a plurality of visual assessments, each visual assessment comprising an eye tracking exercise applicable to evaluate at least one of a plurality of physiological functions, wherein the plurality of physiological functions are across a plurality of categories including reading ability, physical performance vision, and neurological function
Across the independent claims, the invention is implemented as (i) selecting visual assessments spanning reading ability, physical performance vision, and neurological function, (ii) mapping user eye tracking data to a stored data schema for categorization, (iii) retrieving categorized eye tracking data from one or more individuals other than the individual, (iv) computing quantitative data from both sources, and (v) generating and displaying an electronic interface report of the physiological function for the individual based on the computed quantitative data.
