Mixed Reality Display Switching for Shared and Private Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixed reality systems fail to provide seamless switching between shared and private virtual objects without user confusion, leading to hidden operations and unclear visibility of private virtual objects to others.
Innovation Solution
A mixed reality display system with a server and terminals that utilize motion detection to switch between shared and private virtual objects based on user actions, updating object attributes and displaying them differently to avoid confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the private virtual object is displayed only to a specific user and is invisible to other users, then the user's privacy and individual operation authority are protected, but other users cannot recognize the operations performed on the invisible private virtual object, causing confusion
Solution Approach 1:
The patent introduces a camera as an intermediary device that captures the user's hand operations on the private virtual object. The captured images are then transmitted to other users, serving as a mediator that bridges the visibility gap. This allows other users to observe operations on private objects without directly seeing the objects themselves, resolving the contradiction between privacy protection and operation recognition.
2Ease of operation
If the shared virtual object is operated using the private virtual object, then individual customization and control are enabled, but the operation content may be hidden by the user's hand and invisible to other users
Solution Approach 1:
The camera acts as an intermediary that captures hand operations from a different perspective, allowing other users to see operations that would otherwise be hidden by the user's own hand. This resolves the contradiction by providing visibility of operations while maintaining individual control through the private virtual object interface.
Solution Approach 2:
The solution transitions from direct visual observation (2D screen view) to third-person camera visualization (spatial dimension). By capturing operations from an external camera perspective rather than the user's first-person view, the system enables other users to see operations in a different spatial dimension, resolving the hand-occlusion problem.
3Adaptability or versatility
If seamless switching between shared and private virtual objects is implemented, then user flexibility and adaptability are improved, but the system complexity increases due to the need to manage visibility and operation recognition for different object types
Solution Approach 1:
The patent applies a universal camera-based visualization mechanism that works for both shared and private virtual objects. Rather than implementing separate complex management systems for each object type, the camera intermediary provides a unified solution that handles visibility and operation recognition for all object types, reducing overall system complexity while maintaining adaptability.

AI summary
In a mixed reality display system, a server and a plurality of mixed reality display terminals are connected, and virtual objects are displayed. The virtual objects include a shared virtual object for which a plurality of terminals have an operation authority and a private virtual object for which only a specific terminal has an operation authority. The server has virtual object attribute information for displaying the virtual objects in each terminal, and each terminal has a motion detecting unit that detects a motion of a user for switching between the shared virtual object and the private virtual object. When a detection result by the motion detecting unit is received from the terminal, the server updates the virtual object attribute information depending on whether the virtual object is the shared virtual object or the private virtual object, and transmits data of the virtual object after the update to each terminal.
