Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for measuring cognitive functions, particularly in individuals with neurodegenerative conditions like Alzheimer's and Parkinson's, are costly, inefficient, and time-consuming.
Innovation Solution
The development of a platform that uses navigation tasks to quantify cognitive abilities by distinguishing between allocentric and egocentric navigation capabilities, allowing for the generation of assessments and potential enhancements of cognitive skills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physiological techniques and other technology are used to measure the state of brain regions, then measurement precision can be achieved, but cost and time consumption increase significantly
Solution Approach 1:
The patent uses virtual reality navigation tasks as a behavioral copy or proxy to measure cognitive functions related to brain regions. Instead of directly measuring brain activity with expensive physiological techniques, the system captures behavioral outputs (navigation performance) that reflect underlying cognitive processes, thereby achieving measurement precision through indirect but valid behavioral assessment
Solution Approach 2:
The patent replaces complex physiological measurement systems (fMRI, PET, EEG) with a simpler computational system based on virtual reality tasks and algorithmic analysis of behavioral data. This substitution maintains measurement capability while dramatically reducing cost and time requirements
2Measurement precision
If physiological techniques and other technology are used to measure the state of brain regions, then measurement precision can be achieved, but device complexity and cost increase
Solution Approach 1:
The system uses virtual reality environments and behavioral task performance as a simplified copy of complex neural processing. By measuring navigation behavior in virtual spaces, the system infers cognitive function without requiring complex physiological measurement equipment
Solution Approach 2:
The patent substitutes complex physiological measurement devices with a computational platform that uses standard computing hardware, virtual reality rendering, and data analysis algorithms to achieve equivalent measurement precision with far reduced device complexity
3Measurement precision
If traditional assessment methods are used for cognitive functions, then comprehensive measurement can be achieved, but productivity decreases
Solution Approach 1:
The patent merges multiple cognitive assessment functions into a single integrated virtual reality navigation task. By combining spatial navigation, memory, and cognitive flexibility measurements into one unified task paradigm, the system achieves comprehensive measurement while improving productivity through streamlined assessment
Solution Approach 2:
The virtual reality navigation platform serves multiple assessment functions simultaneously - measuring spatial cognition, episodic memory, executive function, and cognitive flexibility within a single task environment, thereby achieving comprehensive measurement with improved efficiency and productivity
Data Source
AI summary
A cognitive platform is disclosed that is configured for either or both of assessing or enhancing the cognitive abilities of an individual based on implementing one or more navigation task(s) in an environment. A first task is rendered that requires the individual to rely on allocentric navigation capabilities to navigate in the environment based on a first set of views of portions of the environment rendered at the user interface. A second task is rendered that requires the individual to rely on egocentric navigation capabilities to navigate in the environment. An indication of a cognitive ability in the individual can be generated based on the difference in the individual's performance at the first task as compared to the second task.
