3D Display View Control for Real-Virtual Object Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted information processing devices face challenges in visual interference when real and virtual objects are three-dimensionally arranged, causing obstruction and difficulty in viewing desired objects due to shielding by other objects.
Innovation Solution
The display apparatus identifies target objects and interfering objects, adjusting the display mode, such as position, transparency, size, or duplication, to eliminate or reduce visual interference, allowing users to view the full picture with minimal user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real bodies and virtual objects are displayed as overlapped in three-dimensional arrangement, then the display richness and immersion are improved, but visual interference occurs where one object shields another, making it difficult to view desired objects
Solution Approach 1:
The patent applies transparency changes (similar to color changes) to the virtual object to resolve visual interference. When a virtual object shields a real body or another virtual object, the system changes the transparency of the shielding virtual object, making it more transparent to allow viewing of the shielded object underneath, thus eliminating the harmful visual interference while maintaining the three-dimensional overlapped display arrangement
Solution Approach 2:
The patent makes the transparency property of virtual objects dynamic by adjusting it in real-time based on spatial relationships. The transparency is not fixed but changes dynamically when interference is detected, allowing the display system to adapt to different viewing scenarios and resolve shielding issues without requiring user intervention
2Object-affected harmful factors
If the display position of virtual objects is changed to eliminate visual interference, then visibility of desired objects is improved, but the device complexity increases due to need for detecting and calculating interference
Solution Approach 1:
The display system performs self-service by automatically detecting visual interference and resolving it through transparency adjustment without requiring user input or manual configuration. The system monitors spatial relationships between real and virtual objects, identifies shielding situations, and autonomously adjusts transparency to eliminate interference, reducing the burden on the user while managing system complexity internally

AI summary
A display apparatus includes a display device and a processor, and the display device displays at least the virtual object among the individual real object cut out from the external real body as an object and the virtual object to be arranged in three dimensions, the object for which the user wants to view is determined as the target object, the object to be interfered when the user views the target object is detected as the interfering object, and when there is an interfering object, the display mode of at least one of the target object and the interfering object is changed so as to eliminate or reduce the interfering caused by the interfering object for viewing the target object.
