Spatial Audio Cognitive Assessment via Source Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring cognitive decline are often invasive and require multiple devices or human experts, leading to less frequent testing and undetected changes in cognitive function.
Innovation Solution
An information processing apparatus and method that uses spatial audio to measure cognitive function by generating audio sounds within a three-dimensional environment and determining the perceived source location based on user response, allowing for non-invasive and accurate assessment of cognitive decline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cognitive tests are used, then cognitive function can be assessed, but the testing process becomes invasive and requires multiple devices or human experts
Solution Approach 1:
The patent combines multiple assessment functions into a single audio-based testing system. Instead of using separate devices for different cognitive tests and requiring multiple experts to analyze various data types, the invention integrates spatial audio processing, cognitive function assessment, and analysis into one unified system that uses audio signals to evaluate multiple cognitive domains simultaneously
Solution Approach 2:
The audio-based testing platform serves multiple cognitive assessment functions through a single interface. The system can evaluate spatial hearing, attention, memory, and reasoning capabilities using the same audio delivery mechanism and processing pipeline, eliminating the need for specialized equipment for each type of cognitive test
2Reliability
If traditional cognitive tests requiring multiple devices and experts are used, then comprehensive assessment can be achieved, but testing frequency decreases and cognitive decline may go undetected
Solution Approach 1:
The system enables automated cognitive function assessment that operates independently without requiring human expert intervention for each test administration. The audio-based platform automatically delivers stimuli, processes responses, and generates cognitive function evaluations, allowing users to perform assessments regularly without scheduling constraints or expert availability limitations
Solution Approach 2:
The invention replaces the mechanical system of manual test administration and expert analysis with an automated audio processing system. Instead of requiring experts to observe and interpret patient responses in person, the system uses audio signal processing algorithms to automatically evaluate cognitive function from recorded responses, enabling frequent unsupervised testing
3Measurement precision
If invasive tests are used to measure cognitive function, then diagnostic accuracy can be achieved, but patient compliance and regular testing decrease
Solution Approach 1:
The patent replaces invasive mechanical testing procedures with non-invasive audio-based assessment. Instead of requiring physical tasks, manual stimuli presentation, or complex equipment interaction, the system delivers cognitive test stimuli through audio signals and processes verbal or auditory responses, making the testing experience comfortable and accessible for patients while maintaining diagnostic precision
