Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current VR/AR systems are used for individual experiences, then device complexity is reduced, but the capability to provide seamless collective experiences for multiple users is lost
Solution Approach 1:
The patent introduces a server as an intermediary component that coordinates communication between multiple VR/AR devices. The server manages user connections, synchronizes content delivery, and facilitates interactions without requiring complex peer-to-peer protocols in each device, thus enabling collective experiences while controlling device complexity.
Solution Approach 2:
The VR/AR device is designed with multi-functional capabilities that allow it to operate both as an individual experience device and as part of a collective experience system. The device can switch between standalone mode and networked mode, providing versatility while maintaining a relatively simple base architecture.
2Ease of operation
If VR/AR systems are designed for seamless collective experiences, then user interaction quality improves, but device complexity increases
Solution Approach 1:
The server acts as a mediator that handles the complexity of coordinating multiple users, managing synchronization, and processing interactions. This allows the VR/AR devices to maintain simple interfaces for users while achieving seamless collective experiences through the backend intermediary system.
Solution Approach 2:
The system implements feedback mechanisms where the server continuously monitors user states, content delivery status, and interaction quality. Based on this feedback, the server dynamically adjusts content synchronization and interaction protocols to maintain seamlessness without requiring complex local decision-making in each device.
3Reliability
If presentation content is delivered to all users simultaneously, then synchronization is improved, but network bandwidth consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-loading and caching presentation content on the server before the actual presentation begins. This allows for rapid simultaneous distribution to all users during the presentation without requiring excessive real-time bandwidth, as the bulk of data transfer occurs in advance.
Solution Approach 2:
The system uses differential updates where only changed or updated portions of content are transmitted to users after the initial full content delivery. This partial action approach maintains synchronization reliability while significantly reducing ongoing network bandwidth consumption during the presentation.
