Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality devices for medical therapy are invasive and can cause anxiety, stress, and fatigue, failing to effectively adapt virtual reality stimulations to a user's emotions for therapeutic purposes, particularly in treating neurodegenerative diseases like Alzheimer's and Parkinson's.
Innovation Solution
An immersive audio-visual headset with a visor and adjustable fixing element, equipped with emotion recognition sensors and a video broadcasting system that adjusts virtual reality experiences in real-time based on detected emotions, minimizing facial contact and using a projector to provide 3D imagery without direct contact, thus reducing invasiveness and enhancing user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual reality devices are used for medical therapy, then cognitive stimulation and emotion recognition capabilities are improved, but user comfort and reduction of anxiety/stress/fatigue deteriorate due to invasive contact
Solution Approach 1:
The device segments the visual field into multiple zones (central zone with first curvature radius, peripheral zones with second curvature radius) to provide different levels of immersion and stimulation. This segmentation allows the system to deliver targeted cognitive stimulation while reducing overall invasiveness by not requiring complete facial coverage.
Solution Approach 2:
The patent introduces an emotion recognition system that acts as an intermediary between the user's emotional state and the virtual reality content delivery. Sensors detect emotional indicators and the system adapts the virtual reality experience accordingly, preventing over-stimulation and reducing anxiety while maintaining therapeutic benefits.
2Measurement precision
If a curved screen is positioned close to the face for 3D effect, then depth perception and virtual reality immersion are improved, but invasiveness and potential discomfort increase
Solution Approach 1:
The visual field is divided into a central zone and peripheral zones, each with different curvature radii. The central zone (first curvature radius) provides the primary 3D effect for depth perception, while the peripheral zones (second curvature radius) extend the field of view with reduced curvature, minimizing facial contact and discomfort while maintaining immersion.
Solution Approach 2:
Different regions of the visual field are assigned different optical properties (curvature radii) based on their functional requirements. The central viewing area has higher curvature for enhanced 3D effect, while peripheral areas have lower curvature for comfort, creating local optimization of both depth perception and user comfort.
3Adaptability or versatility
If multiple sensors are added for emotion recognition, then adaptability to user emotions is improved, but device complexity and invasive contact increase
Solution Approach 1:
The device integrates multiple functions into unified components. The visual display system serves both as the virtual reality interface and as a platform for mounting emotion recognition sensors. The processing system handles both virtual reality rendering and emotion analysis, reducing overall device complexity while maintaining adaptability.
Solution Approach 2:
The patent combines the emotion recognition system with the virtual reality delivery system. Sensors are integrated into the visor structure, and the emotion processing is merged with the existing graphics processing unit, creating a unified system that reduces complexity compared to separate independent systems.
