VR Dementia Diagnosis System Using Immersive Video Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for diagnosing dementia are costly, invasive, and inaccurate due to reliance on high-priced equipment and lengthy, education-dependent psychological tests, which fail to reflect everyday cognitive performance.
Innovation Solution
A VR device and system that provides a comprehensive evaluation of linguistic competence, visual ability, and associative ability through a VR environment with introduction and question videos, allowing for accurate dementia diagnosis without age or education influence, using a Head Mounted Display and user response analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional psychological medical examination methods are used for dementia diagnosis, then diagnosis can be performed, but the examination time is long and patients experience mental pressure and stress
Solution Approach 1:
The patent creates a virtual copy of the examination environment through VR technology. Instead of requiring patients to physically sit through lengthy psychological tests in a clinical setting, the system presents a virtual version of the examination through immersive 3D scenarios. This virtual copying allows the same diagnostic assessment to be conducted in a condensed, stress-free format that maintains diagnostic accuracy while dramatically reducing examination time.
Solution Approach 2:
The patent replaces the mechanical, physical examination process with a digital/virtual system. Traditional paper-based psychological tests and in-person clinical interviews are substituted with interactive VR experiences where patients navigate virtual environments and respond to prompts through natural interactions. This substitution eliminates the time-consuming nature of conventional examinations while maintaining diagnostic validity.
2Measurement precision
If written psychological tests are used for dementia diagnosis, then cognitive assessment can be performed, but the tests are lengthy, rigid, and greatly affected by education level
Solution Approach 1:
The patent implements dynamic adaptation in the VR assessment system. The virtual examination automatically adjusts its difficulty, complexity, and content based on real-time observations of the patient's performance and background information. This dynamic adaptation ensures that the assessment remains appropriate for patients with varying education levels, cultural backgrounds, and cognitive abilities, eliminating the rigidity and education-bias inherent in written tests.
Solution Approach 2:
The system changes multiple parameters of the assessment based on patient characteristics. Instead of using a fixed written test format, the VR system modifies visual complexity, interaction requirements, and task difficulty levels according to the patient's age, education level, and cognitive status. This parameter adjustment allows accurate cognitive assessment across diverse populations without the biases of standardized written examinations.
3Measurement precision
If high-priced equipment such as MRI and blood extraction methods are used for dementia diagnosis, then diagnostic capability is improved, but patient costs and physical pain increase
Solution Approach 1:
The patent creates a virtual copy of the diagnostic process that eliminates the need for expensive physical equipment and invasive procedures. Instead of requiring MRI scans, blood tests, or cerebrospinal fluid extraction, the system uses virtual reality to present cognitive challenges and assess brain function through behavioral observations. This virtual copying maintains diagnostic capability while completely eliminating physical pain and reducing costs.
Solution Approach 2:
The patent replaces invasive mechanical procedures (blood extraction, brain imaging) with a digital assessment system. The VR-based cognitive evaluation substitutes for physical diagnostics by measuring brain function through virtual task performance and neural response patterns. This substitution eliminates all physical harm to patients while providing comprehensive diagnostic information about dementia progression.
