Solution Overview

Problem

Current diagnostic methods for developmental disorders such as autism spectrum disorders (ASD) lack sensitivity and specificity, leading to late diagnosis and ineffective treatments, and there is a lack of adequate tools for measuring developmental progress in young patients.

Innovation Solution

Systems and methods for assessing developmental, cognitive, and mental abilities or disabilities using eye tracking data analysis, specifically monitoring and tracking visual fixation over time in response to predetermined visual stimuli, and comparing it to relative norms to identify markers of conditions like ASD.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional diagnostic methods are used for developmental disorders, then the diagnostic process is simple and familiar, but the sensitivity and specificity are poor leading to late diagnosis

Engineering Contradiction:

Improvediagnostic sensitivity and specificityVSAvoiddiagnostic system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical/observational diagnostic methods with an optical eye tracking system that uses cameras and computer vision algorithms to automatically measure and analyze visual fixation patterns, thereby improving diagnostic precision without requiring complex manual assessment procedures

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces visual fixation patterns as an intermediary biomarker that objectively reflects neurological development status. This intermediary measurement enables more accurate diagnosis by providing quantifiable data about attention and processing patterns that correlate with developmental conditions

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If traditional assessment tools are used for measuring developmental progress, then the assessment process is straightforward, but adequate measurement tools are lacking especially for young patients

Engineering Contradiction:

Improvedevelopmental progress measurement accuracyVSAvoidassessment tool usability

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The eye tracking system requires minimal operator intervention as it automatically captures eye movement data, processes fixation patterns through algorithms, and generates diagnostic reports. The system serves itself by converting raw eye tracking signals into meaningful developmental assessments without requiring complex manual scoring or interpretation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual developmental assessment tools with automated eye tracking technology that objectively measures visual attention patterns, providing precise quantification of developmental progress particularly for young patients who cannot participate in traditional verbal or task-based assessments

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of time

If eye tracking analysis is implemented for early diagnosis, then diagnostic accuracy and timing are improved, but the system complexity and data processing requirements increase

Engineering Contradiction:

Improvediagnosis timingVSAvoideye tracking system complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent implements eye tracking assessment early in development (infancy and early childhood) when visual fixation patterns are already indicative of neurological status. By performing the assessment preliminarily before symptoms manifest or before traditional diagnostic windows close, the system enables earlier intervention while using automated processing to manage the complexity of early developmental measurement

Inventive Principle:

Principle #10Preliminary action

4Reliability

If visual fixation patterns are monitored over time, then treatment effectiveness can be measured, but the requirement for repeated sessions and longitudinal data increases

Engineering Contradiction:

Improvetreatment progress measurement reliabilityVSAvoidassessment time span

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent establishes continuous monitoring of visual fixation patterns through repeated eye tracking sessions over time. This continuous data collection creates a longitudinal profile of developmental progress or treatment response, where each assessment builds upon previous data points to provide a reliable trajectory of change while the automated system efficiently manages the time investment required

Inventive Principle:

Principle #20Continuity of useful action

AI summary

Systems, devices, and methods are described for assessing the risk of developmental, cognitive, social, or mental abilities or disabilities in very young patients (e.g., in the first 2-6 months of life). Generally, the decline in visual fixation of a subject over time with respect to certain dynamic stimuli provides a marker of possible abilities or disabilities (such as ASD). The visual fixation of the subject is identified, monitored, and tracked over time through repeated eye tracking sessions, and data relating to the visual fixation is then analyzed to determine a possible increased risk certain conditions in the subject. A change in visual fixation as compared to similar visual fixation data of typically-developing subjects or to a subject's own, prior visual fixation data provides an indication of a developmental, cognitive, or mental ability or disability.
