Digital Cognitive Impairment Assessment via Video Game Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack an effective tool to detect and assess the recency and degree of cognitive and behavioral impairment caused by cannabinoids, particularly in the context of impaired driving, and there is a challenge in determining the proper dosage of cannabis products.
Innovation Solution
A digital impairment assessment system that uses a computing device to execute cognitive tests in the form of video games to assess psychomotor control, sense of timing, and sustained attention, processing user performance data to determine impairment levels and potentially identify the substance causing impairment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If biological-sampling methods (saliva and blood tests) are used to detect cannabinoid use, then a history of use can be detected, but the recency of use and the degree of cognitive impairment cannot be accurately determined
Solution Approach 1:
The patent replaces biological-sampling methods (mechanical/physical testing) with a digital cognitive assessment system that uses software-based cognitive tests to directly measure impairment levels, providing more accurate real-time detection of recency and degree of impairment without requiring physical sample collection and analysis
Solution Approach 2:
The system changes the measurement parameters from detecting presence of cannabinoids in biological samples to directly assessing cognitive performance parameters (reaction time, accuracy, task completion) that correlate with impairment levels, enabling more precise measurement of recency and degree of impairment
2Measurement precision
If cognitive tests are administered to assess impairment, then accurate measurement of cognitive impairment can be achieved, but the complexity of the assessment system increases
Solution Approach 1:
The patent creates a multi-functional digital assessment platform that can administer multiple types of cognitive tests, process various performance parameters, and provide comprehensive impairment assessment all through a single integrated system, reducing overall complexity while maintaining high measurement precision
Solution Approach 2:
The system uses digital copies of cognitive test protocols and performance metrics that can be standardized and replicated across different devices and users, simplifying the assessment process while maintaining consistent measurement accuracy
3Measurement precision
If multiple cognitive tests are executed to comprehensively assess impairment, then the degree of impairment can be determined, but the time required for assessment increases
Solution Approach 1:
The system implements a tiered testing approach where essential cognitive tests are administered first to determine overall impairment status, with additional specialized tests only administered when needed based on initial results, reducing average assessment time while maintaining comprehensive evaluation capability
Solution Approach 2:
The patent incorporates preliminary screening tests that quickly identify users who require full comprehensive assessment versus those who can be cleared with minimal testing, allowing the system to optimize assessment time based on individual risk profiles and test performance
Data Source
AI summary
Interactive software applications designed to assess a combination of behavioral neuro-physiological characteristics of a user to determine an effect a substance is currently having on the user. In some examples the effect of the substance may be assessed to identify a cognitive impairment caused by a substance and determine the type of substance(s) likely causing the impairment. In some examples the effect of the substance may be assessed to determine a recommended dosage and/or a standard impairing dose threshold for a particular substance.
