Head-Mounted Display Image Variance Control for Motion-Induced Dizziness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted display devices cause dizziness due to large variations in displayed images when enlarged, as they fail to adjust display portion variance in response to user movement.
Innovation Solution
A method and apparatus that detect movement while displaying enlarged images and adjust the display portion variance to minimize image changes, ensuring continuity and reducing dizziness by controlling the head-mounted device's image display based on detected movement and display state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If enlarged images are displayed in virtual space, then image detail visibility is improved, but dizziness is induced due to large variation in displayed image
Solution Approach 1:
The patent applies dynamics by making the display portion variance adjustable based on detected movement. When the user moves their head, the system dynamically changes the variance of the displayed image portion to compensate for the movement, thereby maintaining image stability and preventing dizziness while keeping the enlarged view visible
Solution Approach 2:
The system uses feedback by detecting user movement and using this information to adjust the display portion variance. The movement detection triggers a response that modifies the image display characteristics, creating a closed-loop control system that adapts to user actions in real-time
2Stability of the object's composition
If display portion variance is adjusted based on movement, then image continuity is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical adjustment mechanisms with sensor-based detection and software-based variance adjustment. Instead of physically moving display components, the system uses movement sensors to detect user actions and computationally adjusts the display portion variance, significantly reducing mechanical complexity while maintaining image continuity

AI summary
The disclosure relates to a method of controlling an image display by an electronic device and an apparatus thereof. A method for controlling an image display by an electronic device according to various examples includes: displaying an image; checking a display state of the image; detecting a movement of the electronic device; when the movement of the electronic device is detected, determining a movement variance based on the movement, adjusting a display portion variance based on the display state and the movement variance; and displaying an image having the changed display portion based on the display portion variance.
