Solution Overview

Problem

Users of VR glasses experience motion sickness due to mismatched visual and sensory inputs during avatar movement in virtual environments, and existing vignetting functions are inconvenient to activate or deactivate.

Innovation Solution

A wearable electronic device with a processor that detects avatar movement in a virtual space and applies a changeable vignetting effect to the displayed screen, minimizing motion sickness by adjusting the vignetting based on avatar movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If vignetting function is applied to minimize motion sickness, then motion sickness is reduced, but user immersion in VR content is hindered

Engineering Contradiction:
Improvemotion sicknessVSAvoiduser immersion
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The vignetting function dynamically adjusts the vignetting area size based on the detected movement speed of the avatar. When the avatar moves quickly, a larger vignetting area is applied to reduce motion sickness. When the avatar moves slowly or is stationary, a smaller vignetting area is applied to maintain user immersion. This dynamic adjustment resolves the contradiction by making the vignetting effect adaptive to different usage scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of vignetting area size based on avatar movement speed. By monitoring the speed at which the avatar moves through the virtual environment, the system adjusts the extent of the vignetting effect applied to the display. This parameter change allows the system to optimize between reducing motion sickness and maintaining immersion depending on the current state of the VR experience.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If vignetting function is activated for each application based on user input, then motion sickness can be controlled, but user convenience is reduced due to frequent input requirements

Engineering Contradiction:
Improvemotion sicknessVSAvoiduser convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system automatically detects avatar movement speed and adjusts the vignetting function accordingly without requiring user input. The processor monitors the avatar's movement through the virtual environment and autonomously determines when to apply or adjust the vignetting effect. This self-service approach eliminates the need for users to manually activate or deactivate the vignetting function for each application, significantly improving user convenience while maintaining effective motion sickness control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from avatar movement detection to automatically control the vignetting function. By continuously monitoring the avatar's position and calculating movement speed, the system receives real-time feedback about the user's experience state and adjusts the vignetting effect accordingly. This closed-loop feedback mechanism replaces manual user input with automated control based on actual usage conditions.

Inventive Principle:
Principle #23Feedback
