3D Media Convergence Adjustment via Viewer Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for presenting three-dimensional media content fail to effectively adjust convergence based on viewer position and preferences, leading to suboptimal viewing experiences due to fixed convergence settings that do not account for individual or group variations in distance and seating arrangements.
Innovation Solution
A system and method that utilize a media processor and calibrator to adjust the convergence of three-dimensional media content based on position information obtained from viewers, using distance cameras or image cameras to determine viewer positions and adjust the presentation dynamically, allowing for personalized convergence settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed convergence settings are used in 3D media content presentation, then device complexity is reduced, but viewing comfort and image alignment deteriorate for viewers at different positions
Solution Approach 1:
The patent implements dynamic convergence adjustment by detecting viewer position and automatically modifying convergence parameters in real-time. The system transitions from static fixed settings to dynamic adaptive settings that respond to viewer location, thereby improving viewing comfort without requiring manual intervention from the user.
Solution Approach 2:
The system performs self-calibration by automatically detecting viewer position and adjusting convergence settings without requiring manual input from the viewer. The media processor autonomously optimizes the 3D presentation parameters based on detected viewer characteristics, eliminating the need for users to manually adjust complex convergence controls.
2Ease of operation
If dynamic convergence adjustment based on viewer position is implemented, then viewing comfort is improved, but device complexity and measurement requirements increase
Solution Approach 1:
The patent introduces a camera as an intermediary device to detect viewer position. The camera captures images of the viewer, and the system processes these images to determine viewing angle and distance, thereby indirectly measuring viewer position without requiring direct sensors on the viewer or complex measurement systems.
Solution Approach 2:
The system replaces complex mechanical measurement devices with optical detection using a camera. Instead of using mechanical sensors or direct physical measurement tools to detect viewer position, the patent uses image capture and processing to derive viewing parameters, simplifying the measurement approach while maintaining accuracy.
3Adaptability or versatility
If personalized convergence settings are provided for each viewer, then viewing experience is optimized, but system complexity and processing requirements increase
Solution Approach 1:
The patent applies local quality by providing customized convergence settings tailored to each viewer's specific position and characteristics. Instead of using a single global setting for all viewers, the system adjusts convergence parameters locally for each viewer based on their individual viewing angle and distance, thereby optimizing the viewing experience for each person.
Solution Approach 2:
The system dynamically changes convergence parameters based on detected viewer position and characteristics. The media processor modifies technical parameters such as convergence angle and focal depth in real-time according to each viewer's location, enabling personalized settings without requiring separate hardware systems for each user.
