Head-Mounted Display Virtual Vision Area Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted smart devices with display units struggle to provide an effective combination of virtual and real environments, as the real environment for superimposition cannot be selected or changed, resulting in a simple and poor display effect.
Innovation Solution
An information processing method and apparatus for a head-mounted device that determines a virtual vision area, searches for objects in the environment space that satisfy predetermined conditions, and outputs display content in matching areas on those objects, allowing users to select and change the environment for superimposition, thereby enhancing the display effect of virtuality and reality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display content is superimposed on the real environment viewed by the user, then the combination of virtuality and reality is achieved, but the real environment for superimposition cannot be selected or changed resulting in simple display effect
Solution Approach 1:
The patent implements dynamic selection of real environment objects for virtual content superimposition. The system continuously tracks and identifies objects in the real environment, allowing the superimposition target to change dynamically based on user gaze or selection, rather than being fixed. This enables adaptability while managing complexity through real-time object detection and tracking mechanisms.
Solution Approach 2:
The patent introduces an intermediary processing layer between the display unit and the user's vision. This intermediary system includes object detection algorithms, coordinate transformation modules, and rendering engines that mediate between the virtual content and the real environment, enabling selective superimposition on different real-world objects without requiring direct complex interaction between the display system and the environment.
2Manufacturing precision
If virtual content is superimposed on the real environment, then the display effect of combination of virtuality and reality is achieved, but the display effect is simple and not good
Solution Approach 1:
The patent applies local quality by rendering virtual content with high precision specifically at the location of selected real-world objects, while maintaining lower processing requirements for other areas. The system detects objects and applies detailed virtual content superimposition only to relevant regions, improving display precision where needed without uniformly increasing processing complexity across the entire field of view.
Solution Approach 2:
The patent utilizes parameter changes in the coordinate systems and transformation matrices to achieve precise alignment between virtual content and real-world objects. By dynamically adjusting transformation parameters based on object detection results and user gaze direction, the system achieves high display precision without requiring complex reconfiguration of the entire rendering system.
