Eye Tracking Display Adaptation for VR Fatigue Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional VR and AR devices cause eye fatigue in users due to factors like display resolution and luminance, leading to discomfort and pain, as they do not adapt settings to individual user needs.
Innovation Solution
An electronic device equipped with a camera module for eye tracking, a processor, and memory that adjusts display settings and content output based on user eye fatigue levels, offering two modes: one for changing display settings and another for both display and content settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If display resolution and luminance are increased to improve content quality, then visual fidelity is improved, but eye fatigue increases
Solution Approach 1:
The patent applies dynamics by making display settings adaptive rather than fixed. The system continuously monitors eye fatigue levels through eye tracking and dynamically adjusts display parameters such as luminance, resolution, and refresh rate in real-time based on user condition, allowing the display to transition between high-fidelity mode and fatigue-reducing mode
Solution Approach 2:
The patent changes physical parameters of the display system based on detected eye fatigue levels. When fatigue is detected, the system modifies display parameters including reducing luminance, adjusting resolution, changing refresh rate, or modifying color temperature to create more comfortable viewing conditions while maintaining acceptable visual quality
2Device complexity
If conventional VR/AR devices display content uniformly to all users, then content delivery is simplified, but individual user comfort is compromised
Solution Approach 1:
The patent implements feedback by continuously monitoring eye tracking data and eye fatigue levels, then using this information to automatically adjust display settings and content delivery parameters. This closed-loop system responds to individual user conditions in real-time, providing personalized comfort without requiring manual user input
Solution Approach 2:
The patent applies local quality by customizing display parameters and content delivery to match individual user needs based on their specific eye fatigue levels and viewing conditions. Each user receives tailored visual output optimized for their current state, rather than a one-size-fits-all approach

AI summary
Disclosed is an electronic device including a camera module, a display that displays AR content or VR content, at least one processor operatively connected to the camera module and the display, and a memory operatively connected to the at least one processor and storing the AR content or VR content. The memory may store one or more instructions that, when executed, cause the at least one processor to obtain eye tracking data by using the camera module, to determine an eye fatigue level based on the eye tracking data, and to select one mode between a first mode for changing a setting of the display and a second mode for changing both the setting of the display and an output setting of the AR content or VR content, depending on the eye fatigue level. In addition, other various embodiments identified through the specification are also possible.
