Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current neuropsychological testing methods face challenges in reproducibility of test settings and standardization of scores, as well as qualitative interpretation variability among medical practitioners, leading to incomplete data on cognitive processes and potential misdiagnosis.
Innovation Solution
An apparatus and method for capturing and analyzing individual representational motions with spatial precision, allowing for precise measurement and reporting of neurocognitive mechanisms, including logging timestamps and digitizing handwritten motions to provide standardized and quantifiable data for neuropsychological assessments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated cognitive testing is used (touchscreen, mobile phones, tablet computers), then testing efficiency and data collection speed are improved, but the test administration is materially altered and qualitative process data is lost
Solution Approach 1:
The patent uses optical scanning technology to create digital copies of handwritten responses on paper test forms. The scanning system captures images of the completed test forms, preserving the original handwritten data while enabling automated processing and analysis, thus maintaining the qualitative characteristics of handwritten responses while improving testing efficiency
Solution Approach 2:
The patent introduces an optical scanning system as an intermediary between the paper-based test administration and digital data processing. This intermediary captures and digitizes the handwritten responses without altering the original test-taking process, allowing both traditional paper-based qualitative data collection and automated digital analysis to coexist
2Loss of information
If paper-based handwritten testing is used, then qualitative process data is preserved, but measurement precision and standardization are reduced
Solution Approach 1:
The patent replaces manual measurement and analysis of handwritten responses with automated optical scanning and digital image processing systems. This substitution enables precise measurement of spatial characteristics, timing data, and other quantitative parameters from handwritten responses, significantly improving measurement precision while preserving the qualitative data through digital copying
Solution Approach 2:
The patent transforms physical handwritten responses into digital parameters through optical scanning. The scanning system converts spatial positions, timing information, and other physical characteristics into digital data parameters that can be precisely measured, stored, and analyzed, thereby enhancing measurement precision while maintaining the original qualitative information
3Adaptability or versatility
If manual administration and interpretation by medical practitioners is used, then qualitative interpretation is possible, but reproducibility and standardization of test settings are reduced
Solution Approach 1:
The patent implements automated feedback systems that provide standardized scoring and interpretation of test results. The system automatically analyzes scanned test forms, compares responses against standardized criteria, and provides consistent feedback, thereby improving reproducibility while preserving the ability for practitioners to access and interpret the underlying qualitative data
4Manufacturing precision
If digital touchscreen testing is used, then data standardization is improved, but the test experience and neurocognitive measurement accuracy are altered
Solution Approach 1:
The patent creates digital copies of traditional paper-based test responses through optical scanning, preserving the original test-taking experience and neurocognitive processes while enabling standardized digital data collection and analysis, thus maintaining measurement accuracy while improving data standardization
Data Source
AI summary
Disclosed is an apparatus and corresponding method to capture individual representational motions made by a person while performing a neuropsychological test. A user of the apparatus and method may be allowed to view, edit, classify, and retrieve any captured and recorded motions made by the person. In one embodiment, a capture unit, such as a digitizer, captures the motions made by a person while performing a Clock Drawing Test, and the captured data may then be reported in a myriad of ways. The apparatus and method also provide a means to standardize administration and scoring of writing utensil and paper based neuropsychological testing administered to a person or control and test groups for domestic or international applications. By analyzing individual representational motions made by a person while performing a neuropsychological test, unexpectedly more information may be gleaned from the test than was available to physicians from only a completed drawing.
