Adaptive Cognitive Assessment for Sensitive Multitasking Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cognitive assessment tools are tedious, time-consuming, and insensitive to known cognitive deficits, leading to inaccurate scores and poor compliance, especially in populations with chromosomal abnormalities like 16p.11.2 BP4-BP5, and fail to engage users effectively.
Innovation Solution
A computer-implemented cognitive assessment tool that evaluates user inputs while performing at least two tasks simultaneously, utilizing a computer device to present and adapt tasks, analyze performance measures, and output a cognitive assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional cognitive assessment tools are used, then the assessment process is straightforward and easy to administer, but the tools are tedious for users, time-consuming, and insensitive to known cognitive deficits, leading to inaccurate scores and poor compliance
Solution Approach 1:
The patent transforms static, traditional cognitive assessment tasks into dynamic, adaptive tasks that adjust in real-time based on user performance. The system dynamically modifies task difficulty, timing, and complexity to optimize both measurement precision and user engagement, allowing the assessment to evolve during administration rather than following a fixed protocol
Solution Approach 2:
The system changes multiple parameters simultaneously including task timing, complexity levels, stimulus presentation rates, and feedback mechanisms. These parameter changes enable the assessment to be sensitive to subtle cognitive deficits while maintaining user interest through varied and adaptive task characteristics
2Productivity
If conventional cognitive assessment tools are used, then the administration process is simple, but the assessment is time-consuming for both user and evaluator
Solution Approach 1:
The patent implements continuous assessment where cognitive measurement occurs throughout the entire interaction rather than requiring separate dedicated assessment sessions. Useful actions like navigation and task completion continuously generate cognitive data, eliminating idle time and making the assessment an integrated part of normal device usage
Solution Approach 2:
The system automatically collects, processes, and analyzes cognitive data without requiring evaluator intervention during administration. The assessment administers itself through adaptive algorithms that adjust tasks based on real-time performance, eliminating the need for trained administrators and significantly reducing assessment duration
3Measurement precision
If conventional cognitive assessment tools are used, then the assessment protocol is standardized and easy to administer, but the tools fail to detect subtle cognitive deficits in populations with chromosomal abnormalities
Solution Approach 1:
The patent segments cognitive assessment into multiple fine-grained measurements across different task dimensions (timing, accuracy, adaptability, persistence). Rather than relying on single coarse metrics, the system divides cognitive evaluation into numerous small, sensitive measurements that collectively detect subtle deficits with high precision
Solution Approach 2:
The system adds temporal and adaptive dimensions to traditional cognitive assessment by measuring performance across multiple time points and difficulty levels. This multi-dimensional approach captures subtle cognitive variations that single-point assessments miss, detecting deficits through patterns across dimensions rather than isolated metrics
4Reliability
If conventional cognitive assessment tools are used, then the assessment structure is fixed and easy to implement, but users are unwilling to comply with repeated assessments
Solution Approach 1:
The patent makes the assessment dynamically adaptable to individual user preferences, performance levels, and engagement states. Tasks automatically adjust in real-time based on user responses, maintaining optimal challenge levels that prevent boredom while ensuring reliable measurement, thereby sustaining compliance across repeated assessments
Solution Approach 2:
The system designs assessment tasks that serve multiple functions simultaneously - evaluating cognitive abilities while providing entertainment, education, or practical utility. This multi-functionality increases user willingness to comply with repeated assessments by making them relevant and beneficial beyond mere measurement

AI summary
A computer-implemented cognitive assessment tool is provided for assessing cognitive ability of an individual while multi-tasking. In one embodiment, a computer processing system on which the tool is implemented may receive form the individual first responses to a first task and second responses to a second task, where the first task and the second task are presented to the individual simultaneously. The system may determine that the first task and the second task are performed by the individual based on the first responses and the second responses, and compute a cognitive measure using one or both of the first responses and the second responses. Further, computing the cognitive measure may be based on performance measures of one or both of the first responses and the second responses. Based on the cognitive measure, the system may output a cognitive assessment to the individual.
