Unified Virtual Space for HMD Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for synchronizing multiple head-mounted displays (HMDs) lack the ability to share and synchronize content in real-time across virtual reality spaces, limiting immersive interactive experiences for users.
Innovation Solution
A method and system that allows multiple HMDs to share and synchronize content in a virtual reality space, enabling users to interact with real-world objects and translate these interactions into actions within the virtual environment, using cameras to track real-world objects and synchronize their positions with virtual objects, and allowing users to join or leave shared virtual tours dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple HMDs are used to provide immersive virtual reality experiences, then user engagement and interaction are improved, but synchronization of content across devices becomes complex and difficult to achieve in real-time
Solution Approach 1:
The patent merges multiple HMD devices into a unified virtual space where content is shared and synchronized across all devices. The system combines the virtual environments of multiple users into a single coherent experience, allowing real-time collaboration and interaction without requiring complex individual device management.
Solution Approach 2:
The system creates a universal virtual space that can accommodate multiple HMDs simultaneously, where the same content can be viewed and interacted with by multiple users. This multi-functional approach allows the virtual environment to serve as a shared platform for various users with different devices, simplifying synchronization through a common interface.
2Ease of operation
If real-world objects are tracked and synchronized with virtual objects in real-time, then user interaction with the virtual environment is enhanced, but the system requires complex tracking and coordination mechanisms
Solution Approach 1:
The patent introduces an intermediary system that mediates between the physical world and the virtual environment. This intermediary layer handles the complex tracking and coordination tasks, translating real-world object movements into corresponding virtual object actions, thereby simplifying user interaction while managing the complexity behind the scenes.
Solution Approach 2:
The system replaces complex mechanical tracking mechanisms with computational approaches. Instead of relying on intricate physical tracking hardware, the patent uses software-based tracking and coordinate transformation systems to map real-world positions to virtual space, reducing mechanical complexity while maintaining interaction accuracy.
3Productivity
If content is shared across multiple HMDs in substantial real-time, then collaborative virtual experiences are improved, but network bandwidth and processing requirements increase
Solution Approach 1:
The patent applies local quality by allowing each user to view the virtual content from their specific perspective and location. Instead of transmitting identical content to all HMDs, the system optimizes the content delivery based on each user's viewpoint, reducing redundant data transmission while maintaining the collaborative experience.
Solution Approach 2:
The system dynamically adjusts content synchronization based on user actions and environmental changes. Rather than continuously transmitting all content data, the patent updates only the necessary portions of the virtual environment in real-time, optimizing network bandwidth usage while maintaining collaborative immersion.

AI summary
A method for sharing content with other HMDs includes rendering content of a virtual environment scene on a display screen of a head-mounted display associated with a first user. The display screen rendering the virtual environment scene represents a virtual reality space of the first user. A request to share the virtual reality space of the first user is detected. The request targets a second user. In response to detecting acceptance of the request to share, the virtual reality space of the first user is shared with the second user. The sharing allows synchronizing the virtual environment scene rendered on the head mounted display of the first and the second users.
