Solution Overview

Problem

Current cognitive training methods for age-related cognitive decline and Mild Cognitive Impairment (MCI) face challenges such as lack of generalization and enduring effect, limiting their applicability and effectiveness in improving overall cognitive status.

Innovation Solution

A computer-based exercise that improves the efficiency of eye movements by using a series of graphical elements with varying discriminability, requiring participants to rapidly identify matching targets amidst distractors, with adaptive adjustments in stimulus intensity based on performance, to enhance visual memory and cognition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional cognitive training methods are used, then some cognitive improvements may be achieved, but the benefits do not generalize to other cognitive tasks and do not endure over time

Engineering Contradiction:

Improveenduring effectVSAvoidgeneralization

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The eye movement training exercise is designed to improve multiple cognitive functions simultaneously (visual attention, memory, processing speed) through a single multi-functional training paradigm, rather than separate specialized training for each function, thereby achieving both generalization and enduring effects

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system incorporates adaptive feedback mechanisms that adjust stimulus difficulty based on participant performance in real-time, ensuring optimal challenge level that maintains engagement and promotes lasting cognitive improvement through continuous adaptation

Inventive Principle:

Principle #23Feedback

2Reliability

If cognitive training exercises are made more difficult to improve cognitive status, then training effectiveness increases, but participant engagement and completion decrease

Engineering Contradiction:

Improvetraining effectivenessVSAvoidparticipant engagement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The exercise dynamically adjusts difficulty levels based on participant performance, transitioning from easier stimuli to more challenging ones as the participant improves, thereby maintaining optimal engagement and motivation while ensuring progressive learning and training effectiveness

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system modifies key parameters such as stimulus duration, inter-stimulus interval, and difficulty level based on performance metrics, creating an adaptive training protocol that balances challenge and competence to maximize both effectiveness and engagement

Inventive Principle:

Principle #35Parameter changes

3Speed

If the exercise requires rapid identification of matching targets, then information extraction speed improves, but accuracy may decrease due to time pressure

Engineering Contradiction:

Improveinformation extraction speedVSAvoididentification accuracy

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The exercise uses periodic stimulus presentation with controlled intervals, allowing participants to process information at optimal rates while maintaining rapid response expectations, thereby balancing speed and accuracy through rhythmic training patterns

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system replaces purely reactive response mechanisms with guided eye movement control, using visual guidance cues and adaptive timing to orchestrate the balance between rapid processing and accurate identification through controlled visual attention patterns

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Computer-implemented method for enhancing a participant's cognition, including, e.g., visual memory, utilizing a computing device to present visual stimuli for training, and to record responses from the participant. Multiple graphical elements are provided for visual presentation to the participant. A temporal sequence of a plurality of the graphical elements is visually presented, including displaying each graphical element in the sequence at a respective location in a visual field for a specified duration, then ceasing to display the graphical element. The presented graphical elements include at least two matching graphical elements. The participant is required to respond to the presented sequence, including indicating locations of matching graphical elements. A determination is made as to whether the participant responded correctly, and the duration modified based on the determining. The visually presenting, requiring, determining, and modifying are repeated one or more times in an iterative manner to improve the participant's cognition.
