Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereo visual display units are limited in their ability to simultaneously utilize public or shared information and private information in a virtual space cooperation environment, and current technologies fail to effectively mix multiple stereo image spaces for users, restricting their application in mixed reality scenarios.
Innovation Solution
A face-mounted display apparatus that combines an external image processor to mix actual and artificial stereo images with a user information extractor, image creator, image mixer, and image output unit to synchronize and display these images in a single three-dimensional virtual space, allowing for the integration of multiple external image signals and user-specific visual information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing stereo visual display units are used, then a single stereo image can be displayed, but the ability to simultaneously utilize public or shared information and private information in a virtual space cooperation environment is limited
Solution Approach 1:
The system segments visual information into multiple distinct stereo image spaces (public/shared space and private space), allowing independent processing and rendering of each space before combining them. This segmentation enables the display system to handle different types of information separately while maintaining their individual characteristics, thus resolving the contradiction between versatility and complexity.
Solution Approach 2:
The display apparatus is designed to perform multiple functions: displaying public stereo images, displaying private stereo images, and mixing these multiple image spaces simultaneously. This multi-functionality allows a single device to handle various information types (public and private) without requiring separate display systems, improving adaptability while managing complexity through integrated design.
2Adaptability or versatility
If multiple stereo image spaces are mixed, then a unified three-dimensional view combining public and private information is achieved, but the device complexity increases
Solution Approach 1:
The system introduces an intermediary mixing mechanism that receives multiple stereo image spaces, processes them through coordinate transformation and synchronization, and outputs a unified mixed image. This intermediary layer manages the complexity of mixing multiple spaces by providing a structured approach to integration, allowing the system to achieve versatile image mixing capability while containing complexity within the mixing module.
Solution Approach 2:
The system handles multiple stereo image spaces by introducing an additional dimensional layer of processing - treating each stereo image space as a separate dimensional entity that needs to be transformed, synchronized, and integrated. This dimensional approach allows complex multi-space mixing to be managed through systematic coordinate transformations and synchronization operations, making the complexity manageable while achieving high adaptability.
3Reliability
If a hologram display device is used, then a natural sense of depth is achieved, but it is mostly only used for special effects in movies or manufactured as a prototype and not suitable for general users
Solution Approach 1:
Instead of using complex holographic technology that is difficult to manufacture and access, the system creates a simplified copy or simulation of the holographic depth effect using multiple stereo image spaces. By rendering virtual objects with appropriate depth cues and perspective transformations in a mixed reality environment, the system achieves a natural sense of depth perception that is accessible to general users and manufacturable with current technology, while maintaining the essential visual characteristics of holographic displays.

AI summary
A display apparatus for a mixed reality environment includes an image processor for mixing an actual image of an object around a user and a artificial stereo images to produce multiple external image signals, a user information extractor for extracting the user's sight line information including the user's position his/her eye position, direction of a sight line and focal distance; an image creator for creating a stereo image signal based on the extracted user's sight line information; an image mixer for synchronously mixing the multiple external image signals and the stereo image signal; and an image output unit for outputting the mixed image signal to the user.
