Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video live streaming technologies using virtual images lack dynamic lens movement, resulting in monotonous and boring video content due to fixed lens positions and orientations, which fail to capture the richness and interest of the scene.
Innovation Solution
A method and apparatus that control the position and orientation of a virtual lens to move in conjunction with the movement of a virtual image's hand within a preset range, allowing for dynamic scene capture and generation of video data with enhanced richness and interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lens position is kept fixed to ensure the virtual image appears in the video screen, then the video content becomes monotonous and boring, but changing the lens position introduces dynamic movement that improves video richness
Solution Approach 1:
The patent applies the Dynamics principle by making the lens position dynamic rather than fixed. The lens position is adjusted in real-time based on the virtual image's position and hand movement, allowing the video content to be rich and varied while automatically maintaining proper composition. This resolves the contradiction by making the system adaptive rather than static.
Solution Approach 2:
The patent implements feedback by continuously monitoring the virtual image's position and hand movement, then using this information to adjust the lens position accordingly. This closed-loop control ensures that the lens follows the virtual image naturally, providing dynamic video content while maintaining stable composition without requiring manual intervention.
2Adaptability or versatility
If the lens orientation is kept fixed to simplify the system, then the video lacks dynamic viewing angles, but adjusting the lens orientation adds visual variety while increasing system complexity
Solution Approach 1:
The patent makes the lens orientation dynamic by linking it to the virtual image's orientation and hand movement. The lens orientation adjusts automatically based on the virtual image's facing direction, providing varied viewing angles while keeping the control mechanism simple and integrated within the existing virtual image rendering system.
3Adaptability or versatility
If the virtual image moves in a fixed scene range to maintain consistent lens information, then the video becomes monotonous, but allowing free movement changes lens information that improves video quality
Solution Approach 1:
The patent uses feedback to continuously track the virtual image's position and hand movement, then adjusts the lens information dynamically to match. This ensures that lens information remains consistent with the virtual image's current state while allowing free movement throughout the scene, resolving the contradiction between movement freedom and information consistency.
4Adaptability or versatility
If the lens follows the virtual image hand movement, then the video achieves dynamic selfie effect and improved viewing experience, but requires real-time coordinate transformation that increases processing complexity
Solution Approach 1:
The patent merges the lens control functionality with the virtual image rendering system. By integrating the lens position and orientation adjustments into the existing coordinate transformation pipeline of the virtual image system, the patent achieves dynamic selfie effect without requiring separate complex processing systems. The lens follows the virtual image hand movement through unified coordinate management.
