Fixed Mask Visual Overlay for VR Dizziness Mitigation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Motion sickness, including dizziness, occurs when the visual and vestibular movements mismatch, particularly in virtual reality, augmented reality, and other immersive experiences, as users experience disorientation and discomfort due to inconsistent visual and physical cues.

Innovation Solution

An electronic device method that adds a specific mask to the visual content in a field of view when a mask function is activated, showing a part of a second reality mode, with the mask's location fixed to reduce dizziness, using a processor to manage the visual content and reality mode transitions smoothly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If visual content in virtual reality or augmented reality is displayed without a fixed mask, then the user experiences full visual immersion and content visibility, but the user suffers from dizziness and motion sickness due to visual-vestibular mismatch

Engineering Contradiction:

Improvedizziness and motion sicknessVSAvoidvisual content visibility

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The visual content is segmented into multiple regions with different characteristics. A central region displays the second reality mode content (VR/AR) while peripheral regions display the first reality mode content (real world), allowing users to access both virtual and real visual information simultaneously without experiencing motion sickness

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the visual field are assigned different qualities and functions. The central region provides immersive virtual content while peripheral regions provide stable real-world reference, creating local differences in visual processing that prevent visual-vestibular conflict

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If a mask is added to visual content to mitigate dizziness, then user comfort is improved, but the visual content is partially obscured and user experience is reduced

Engineering Contradiction:

Improveuser comfort and dizziness mitigationVSAvoidvisual content clarity

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The solution transitions from a 2D mask overlay to a spatially distributed multi-region display approach. By utilizing different spatial zones (central vs. peripheral regions) with distinct reality modes, the system provides both comfort and full visual information without the need for obscuring masks

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Stability of the object's composition

If the mask location is fixed to reduce dizziness, then visual stability is improved and dizziness is mitigated, but the adaptability to different viewing conditions is reduced

Engineering Contradiction:

Improvevisual content stabilityVSAvoidadaptability to viewing conditions

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the boundaries and characteristics of different reality mode regions based on user behavior and environmental conditions. The processor monitors user actions and automatically modifies the visual content distribution to maintain both stability and adaptability across different viewing scenarios

Inventive Principle:

Principle #15Dynamics
