Solution Overview

Problem

Current methods for assessing neurological and mental disorders, such as Alzheimer's, Parkinson's, autism, and schizophrenia, lack effective tools for early detection and monitoring of visual and cognitive impairments, relying on costly and burdensome brain imaging and qualitative behavioral assessments that do not quantify visual deficits effectively.

Innovation Solution

A system and method for quantitative assessment of functional impairment using a combination of input, display, and control devices, presenting dynamic scenes to subjects and analyzing their responses to diagnose and recommend interventions, incorporating artificial intelligence for real-time scoring and dynamic testing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If brain imaging and qualitative behavioral assessments are used for diagnosis, then diagnostic accuracy is improved, but cost and patient burden increase

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidcost and burden
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses video recording and analysis to create a replicable, standardized assessment of visual motion processing. Instead of expensive brain imaging, the system captures behavioral responses on video and analyzes them quantitatively, creating a copy of the diagnostic process that is both accurate and scalable.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces complex medical imaging equipment with a simple video-based assessment system. By substituting mechanical/technical imaging systems with a video analysis approach, the system achieves diagnostic capability at a fraction of the cost and complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If routine neurological examination is performed, then ease of administration is improved, but detection of visual abnormalities is reduced

Engineering Contradiction:
Improveease of administrationVSAvoiddetection of visual abnormalities
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent incorporates visual motion processing assessment into the routine neurological examination protocol before other tests are administered. By performing this specific assessment early in the examination process, visual abnormalities are detected before the patient fatigues or becomes less cooperative.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides immediate feedback during the visual motion processing assessment by analyzing the patient's eye movements and head tracking in real-time. This continuous feedback allows the examiner to adjust the assessment dynamically and ensures that visual abnormalities are captured even during routine examination.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If quantitative assessment with continuous feedback is implemented, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvequantification of visual deficitsVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses a single video recording system to perform multiple functions: capturing visual motion processing responses, recording patient behavior, and providing a basis for quantitative analysis. This multi-functional approach achieves precise measurement without proportionally increasing device complexity.

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

Solution Approach 2:

The system introduces video analysis software as an intermediary between the patient's natural behavior and the quantitative measurement. This intermediary automatically extracts motion processing parameters from video data, providing precise quantification without requiring complex direct measurement equipment.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method is presented to address quantitative assessment of visual motion discrimination in a subject, where the method comprises the steps of: (1) presenting a scene, comprising a plurality of elements and a background, to a subject on a display; (2) moving a plurality of elements relative to the scene; (3) receiving feedback from the subject; (4) quantitatively refining the feedback; (5) modulating the movement relative to accuracy of the received feedback; (6) monitoring the response error; (7) calculating a critical threshold parameter for the subject; and (8) recording a critical threshold parameter onto a tangible computer readable medium. An apparatus for quantitative assessment of visual motion discrimination of a subject comprising a display device, an input device, a control device, and a tangible computer readable medium. In its simplest sense, a quantitative assessment profile of visual motion discrimination by psychophysical responses is generated on a tangible computer readable medium.
