Solution Overview

Problem

Current cognitive testing methods lack effectiveness in assessing cognitive abilities such as attention, memory, and ocular-motor functions, as they fail to provide a standardized and reliable means to evaluate eye movement patterns and mathematical processing efficiency.

Innovation Solution

A computer-implemented method for administering cognitive tests that displays numbers at predefined positions along an infinity loop path, tracking eye movements, and scoring based on both mathematical responses and ocular metrics, ensuring consistent and reliable assessment across trials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional cognitive testing methods are used, then the test administration is simple, but the assessment reliability and measurement precision of cognitive abilities are insufficient

Engineering Contradiction:
Improveassessment reliabilityVSAvoidtest system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple assessment dimensions (mathematical processing, eye movement tracking, fixation behavior) into a single integrated cognitive test system. The eye-tracking component merges ocular-motor function assessment with cognitive processing evaluation, creating a multi-modal assessment platform that simultaneously measures multiple cognitive abilities through coordinated mathematical tasks and physiological monitoring

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cognitive test system is designed to assess multiple cognitive abilities (attention, memory, mathematical processing, ocular-motor functions) through a single standardized platform. The eye-tracking component serves multiple functions by simultaneously monitoring fixation positions, tracking eye movement paths, and measuring response times, making the system universally applicable to various cognitive assessment needs

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If numbers are displayed at random positions, then the test appears less predictable, but the measurement precision and reliability of eye movement patterns decrease

Engineering Contradiction:
Improveeye movement measurement precisionVSAvoidtest variability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent establishes predefined display positions and structured trial sequences before administering the cognitive test. The eye-tracking component is calibrated with predetermined fixation points and standardized presentation protocols, ensuring that eye movement measurements are taken from consistent starting positions and follow standardized paths, thereby improving measurement precision while maintaining test structure

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system varies test parameters (number sets, display positions within predefined locations, trial sequences) across different administrations to maintain adaptability. By changing specific parameters while preserving the overall structured framework of predefined positions and standardized measurement protocols, the system achieves both reliability through consistency and versatility through parameter variation

Inventive Principle:
Principle #35Parameter changes

3Productivity

If eye tracking is added to cognitive testing, then the comprehensive evaluation of cognitive abilities improves, but the device complexity and cost increase

Engineering Contradiction:
Improveevaluation efficiencyVSAvoidtesting equipment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The eye-tracking component automatically records and analyzes ocular-motor functions without requiring additional manual intervention or separate assessment procedures. The system self-calibrates using predefined fixation points and automatically processes eye movement data alongside mathematical task performance, eliminating the need for separate ocular-motor testing and reducing overall assessment time while maintaining comprehensive evaluation capabilities

Inventive Principle:
Principle #25Self-service

AI summary

Techniques for generating and administering an oculo-cognitive addition test. Some aspects include identifying, by a system, a set of numbers that are to be displayed to a user during a trial of a cognitive test. The set of numbers includes at least two numbers. The system can administer the trial of the cognitive test, including, for each number in the set of numbers: displaying the number at a particular position of a display environment; tracking, by the system and using one or more optical sensors, eye movement of the user seeking the number in the display environment; and receiving, by the system and after having displayed the number for a time, a command that is to advance or end the cognitive test.
