Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual image sharing systems, such as those disclosed in Patent Literature 1, face issues where virtual objects operated by users appear differently, leading to difficulty in recognition and potential unwanted operations being visible to others.
Innovation Solution
A virtual image sharing method and system that allows for shared virtual images to be displayed on multiple devices, with modes enabling synchronized or independent changes in display modes based on user operations, ensuring privacy and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual object is operated by one user in a shared virtual image, then the virtual object can be modified according to user needs, but the virtual object appears differently to each user making it hard to recognize and potentially causing unwanted operations to be visible to others
Solution Approach 1:
The patent divides the virtual image display into multiple independent virtual images, each visible to specific users. When a user operates a virtual object, only the corresponding virtual image is modified, while other virtual images remain unchanged. This segmentation allows users to operate virtual objects independently without affecting others' views, resolving the contradiction between ease of operation and recognition reliability.
Solution Approach 2:
The patent applies different display modes to different virtual images based on user operations. When a user performs an operation, the system changes the display mode of the corresponding virtual image locally, while other virtual images maintain their original display modes. This local quality approach ensures that only the affected virtual image reflects the operation, maintaining recognition accuracy and preventing unwanted operations from being visible to others.
2Adaptability or versatility
If operations on virtual objects are performed excessively, then user needs can be met, but the virtual object becomes hard to recognize
Solution Approach 1:
The patent segments virtual objects into multiple independent virtual images, each associated with specific users. When operations are performed on one virtual image, only that specific virtual image is modified, while others remain stable. This segmentation limits the impact of excessive operations to only the affected virtual image, preserving recognition reliability across the entire shared virtual image system.
Solution Approach 2:
The patent dynamically adjusts the display mode of virtual images based on user operations. When a user operates a virtual object, the system changes the display mode of the corresponding virtual image to reflect the operation. This dynamic adjustment allows the system to adapt to user needs while maintaining recognition accuracy by only modifying the affected virtual image's display mode.
3Ease of operation
If users can operate virtual objects independently, then privacy and usability are improved, but synchronization of virtual image changes across multiple devices becomes complex
Solution Approach 1:
The patent segments virtual image changes into independent operations for each user. When a user operates a virtual object, only the corresponding virtual image is modified, and this change is reflected only in that user's view. This segmentation allows independent operation while simplifying synchronization, as only the affected virtual image needs to be updated, not the entire virtual image system across all devices.
Solution Approach 2:
The patent applies local quality changes to specific virtual images based on user operations. When a user performs an operation, the system changes the display mode of the corresponding virtual image locally, without affecting other virtual images or requiring global synchronization. This approach simplifies the synchronization process by limiting changes to only the affected local virtual image, reducing the complexity of coordinating changes across multiple devices.
