Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality objects are presented across different physical environments, then the user experience becomes more immersive and engaging, but synchronizing objects in terms of position and time becomes difficult
Solution Approach 1:
The patent introduces a server as an intermediary component that receives participant state information from multiple augmented reality devices, processes this data, and distributes synchronized updates to all participants. This mediator architecture resolves the synchronization difficulty by centralizing the coordination logic, allowing objects to be consistently positioned and timed across different physical environments without requiring direct peer-to-peer synchronization between devices.
Solution Approach 2:
The system implements a universal coordinate system and shared virtual space that can accommodate multiple participants in different physical environments. This universal framework allows augmented reality objects to be positioned and synchronized across diverse locations by mapping all participant views to a common reference frame, enabling consistent object placement and timing regardless of the participant's physical location.
2Ease of operation
If a shared virtual space is generated and populated with coparticipant controlled objects, then remote participants can interact seamlessly, but network communication and data synchronization complexity increases
Solution Approach 1:
The server acts as a centralized intermediary that manages the shared virtual space and coordinates all interactions between remote participants. Instead of requiring complex peer-to-peer communication protocols between multiple devices, the server consolidates the synchronization logic, receiving state information from all participants and distributing updated states. This approach simplifies the overall system architecture by centralizing complexity in a single coordination point rather than distributing it across multiple devices.
Solution Approach 2:
The system creates virtual copies of participant-controlled augmented reality objects in the shared virtual space. Each participant's controlled object is replicated and positioned in the shared environment, allowing other participants to interact with these copies as if they were physically present. This copying mechanism enables seamless interaction across remote locations without requiring direct real-time connection between all participant devices, reducing communication complexity.

AI summary
Provided is a method of establishing a remote multiparticipant augmented reality session such that participants in the remote multiparticipant augmented reality session are at different locations and are in different physical environments. Augmented reality objects may be populated in a shared virtual space that has components of both physical environments and some of those augmented reality objects are controlled by the remote participant by exchanging participant state information.
