Adaptive Projection Alignment for Rotated Display Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies fail to dynamically adjust the projection direction and content display to align with the orientation and position of the target content, causing viewing inconveniences when the target content is shifted or rotated.
Innovation Solution
A method and apparatus that detect target content within a projection plane, acquire projection information, and project it based on the display state, including adjusting the projection direction and region to align with the content's orientation and position, using modules for detection, acquisition, and projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projection direction is fixed, then the device complexity is reduced, but the adaptability to different content display directions deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the projection direction by detecting the display direction of target content and automatically adjusting the projection beam direction to match. This makes the projection system adaptable to different content orientations without requiring manual reconfiguration, resolving the contradiction between fixed simplicity and dynamic adaptability.
Solution Approach 2:
The system uses feedback from detecting the display direction of target content to automatically adjust the projection direction. This closed-loop control enables the projection beam to adapt to content orientation changes, achieving versatility while maintaining automated operation that reduces perceived complexity.
2Ease of operation
If the projection region is fixed, then the device complexity is reduced, but the viewing convenience when content is near the edge deteriorates
Solution Approach 1:
The projection region is dynamically adjusted based on the detected position and orientation of target content. When content is near the edge or rotated, the system automatically modifies the projection region boundaries and orientation to maintain optimal viewing conditions, improving ease of operation without requiring manual intervention.
Solution Approach 2:
The system performs self-adjustment of the projection region based on automatic detection of content characteristics. This self-service capability allows the projection system to adapt to edge-case scenarios and rotated content automatically, enhancing viewing convenience while minimizing the need for complex manual configuration mechanisms.
3Manufacturing precision
If the projection direction does not match content display direction, then the projection system is simpler, but the display quality and user experience deteriorate
Solution Approach 1:
The system performs preliminary detection of the target content's display direction before projection, and pre-adjusts the projection beam direction to match. This preliminary alignment action ensures high projection alignment precision from the start, avoiding the need for complex real-time adjustment mechanisms during content display.
Solution Approach 2:
The patent replaces complex mechanical alignment mechanisms with automated detection and control systems. By using detection modules to identify content orientation and electronically controlling the projection direction, the system achieves high alignment precision while reducing mechanical complexity.
