Naked-Eye Stereoscopic Display Viewer Positioning via Continuous Test Pattern
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracker type naked-eye stereoscopic display systems face challenges in accurately determining a viewer's position within the viewing area due to individual differences and the discontinuous nature of test patterns, making it difficult for viewers to adjust their position correctly.
Innovation Solution
An information processing apparatus and method that generates a continuous test pattern where the image element's appearance changes based on the viewing position, allowing for precise determination of the viewer's position relative to the viewing area, using a test pattern generation unit that creates a multiplexed image indicating the positional relationship between the viewer and the viewing area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a discontinuous test pattern is used to indicate viewing position, then the device complexity is reduced, but the measurement precision of viewer position deteriorates
Solution Approach 1:
The test pattern uses continuous parameter changes (image size, brightness, or position) to represent different viewing positions. As the viewer moves within the viewing area, the displayed image parameters change continuously, enabling precise position detection while maintaining simple pattern design
Solution Approach 2:
The patent replaces complex mechanical position measurement systems with an optical feedback system. Instead of using sensors or mechanical devices to detect viewer position, the system uses visual feedback through continuously changing image parameters that the viewer can observe and use for self-adjustment
2Ease of operation
If a standard face model is used to calculate eye positions from face measurement information, then the ease of operation is improved, but the measurement precision deteriorates due to individual differences
Solution Approach 1:
The system enables viewers to self-correct their position using visual feedback from the continuous test pattern. Instead of relying on potentially inaccurate automated calculations from standard face models, viewers can directly observe the continuous image changes and adjust their own positioning to achieve the correct viewing position
Solution Approach 2:
The system implements a feedback mechanism where the test pattern continuously changes based on the viewer's position relative to the viewing area. This continuous visual feedback allows viewers to understand their position accuracy and make real-time adjustments, compensating for errors introduced by standard face model calculations
