3D Video Display Apparatus Gaze Tracking Fatigue Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying 3D video images across multiple screens cause eye fatigue due to frequent depth changes and increased visual load when a user switches between different 3D video display screens.
Innovation Solution
A 3D video display apparatus that detects frequent changes in the user's viewing state and restricts the display to 2D when the viewing action exceeds a predetermined frequency, using a combination of cameras and light emitting units to track the user's gaze and detect high-frequency switching between 3D video display screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple 3D video display screens are displayed with different depth information, then the user can view diverse 3D video content, but the user's visual system is overloaded and eye fatigue increases
Solution Approach 1:
The system uses cameras to detect the user's viewing state and provides feedback by controlling the display apparatus. When frequent viewing state changes are detected, the system automatically switches from 3D to 2D display mode, creating a closed-loop feedback mechanism that protects the user's visual system while maintaining viewing flexibility
Solution Approach 2:
The display mode dynamically adjusts between 3D and 2D based on real-time detection of user viewing behavior. The system transitions from a static 3D display to a dynamic mode that adapts to user needs, switching to 2D when fatigue risk is detected and returning to 3D when viewing is stable
2Ease of operation
If the user frequently switches viewing targets between multiple 3D video display screens, then the user can access different video content, but the depth transition becomes rough and visual load increases
Solution Approach 1:
The detection apparatus continuously monitors viewing state changes and provides feedback to the control apparatus. When the number of viewing state changes exceeds a threshold within a predetermined time period, the system responds by switching to 2D display mode, creating a feedback mechanism that reduces visual load during frequent content switching
Solution Approach 2:
The system performs preliminary detection of viewing state changes before the user experiences excessive visual load. By detecting frequent switching patterns in advance, the system proactively switches to 2D mode to prevent visual system overload before it occurs
3Productivity
If 3D video images are displayed with frequent depth changes, then the user can experience dynamic 3D content, but smooth depth transition cannot be achieved and eye fatigue increases
Solution Approach 1:
The system dynamically adjusts the depth display mode based on user viewing stability. When viewing state is stable, the system maintains dynamic 3D content with depth changes. When frequent switching is detected, the system transitions to a static 2D mode, creating a dynamic adaptation that balances content engagement with visual comfort

AI summary
A three-dimensional (3D) video display apparatus includes: a viewing action detecting unit which detects whether or not a viewing state of a user who views a plurality of 3D video display screens with a viewing target being changed between the 3D video display screens has changed a predetermined number of times or more in a predetermined time period; and a control unit which restricts user's viewing action of viewing a 3D video image displayed by an image display unit when the viewing action detecting unit detects that the viewing state of the user has changed the predetermined number of times or more in the predetermined time period.
