Solution Overview
Problem
Existing brain health programs for improving visual divided attention in older adults are inconvenient, expensive, and lack dynamic adaptivity and complexity, limiting their effectiveness in enhancing cognition and daily living abilities.
Innovation Solution
A computer-based system and method that presents target images and peripheral locations within a visual field, requiring participants to select the correct images while adapting presentation time based on performance, incorporating game elements to enhance engagement and cognitive training through visual divided attention exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facilitator-assisted training programs are used, then training effectiveness is maintained, but convenience and cost-effectiveness deteriorate
Solution Approach 1:
The training system enables self-service through automated computer-based delivery, eliminating the need for facilitator intervention. The system automatically presents stimuli, tracks responses, adjusts difficulty levels, and provides feedback, allowing participants to independently complete training exercises without external assistance.
Solution Approach 2:
The patent replaces the mechanical/facilitator-based training system with an automated computer-based system. The computer automatically manages all training components including stimulus presentation, response recording, performance monitoring, and difficulty adjustment, substituting human facilitation with electronic automation.
2Reliability
If facilitator-assisted training programs are used, then training effectiveness is maintained, but cost deteriorates
Solution Approach 1:
The system eliminates the need for paid facilitators by implementing self-service automated training. The computer-based system handles all training functions independently, reducing operational costs while maintaining training quality through standardized protocols and adaptive algorithms.
Solution Approach 2:
The patent substitutes the costly facilitator-based delivery model with an automated electronic system. The computer-based platform reduces personnel costs, infrastructure requirements, and operational expenses while delivering the same training effectiveness through standardized digital interventions.
3Device complexity
If static training programs are used, then program simplicity is maintained, but adaptability to individual performance deteriorates
Solution Approach 1:
The training program incorporates dynamic adaptivity by continuously adjusting difficulty levels based on participant performance. The system monitors response accuracy and time, automatically modulates stimulus characteristics, and adapts task complexity to match the participant's current ability level, transforming a static program into a dynamic, responsive training environment.
Solution Approach 2:
The system implements feedback mechanisms that monitor participant performance in real-time and use this information to adjust training parameters. Performance data feeds back into the system to automatically modify difficulty levels, stimulus presentation rates, and task requirements, creating a closed-loop adaptive training system.

AI summary
Computer-implemented method for enhancing cognition of a participant. A first target image of a set of target images is visually presented for a specified presentation time at a first location in a visual field that includes multiple peripheral locations, each at least a specified distance from the first location. Substantially simultaneously, a first peripheral location in the visual field is visually indicated for the presentation time, after which the visually presenting and indicating are ceased. Candidate target images with a specified discriminability are visually presented, including the first target image. The participant is required to select the target image from among the candidates. If the participant correctly selected the first target image, the participant is required to select the first peripheral location from the multiple peripheral locations. The presentation time is adaptively modified based on the correctness/incorrectness of the participant's selections. The process is repeated to improve the participant's cognition.
