Solution Overview
Problem
Current virtual reality technologies fail to provide an immersive experience when users are in different locations, and network errors can disrupt the shared experience, lacking effective methods to maintain interaction and minimize disturbances during content appreciation.
Innovation Solution
An electronic apparatus and system that renders and transmits Virtual Reality (VR) images by processing motion information from multiple display devices, allowing synchronized rendering and transmission of VR content, including object movements and sound, to ensure a shared immersive experience across different locations, even in the presence of network errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If VR images are transmitted in real-time between users in different locations, then interaction and immersion are improved, but network errors and disruptions increase
Solution Approach 1:
The system performs preliminary actions by predicting user motion and pre-rendering VR images before they are actually needed. The server predicts future head positions and orientations, prepares corresponding VR images in advance, and stores them for immediate transmission, thus maintaining real-time interaction while reducing network dependency during actual viewing.
Solution Approach 2:
The system cushions against network errors by implementing error correction codes and redundant transmission mechanisms. When network packets are lost or corrupted, the server can retransmit critical data or provide alternative lower-quality streams, ensuring continuous playback without disrupting the immersive experience.
2Manufacturing precision
If high-resolution VR images are transmitted to maintain image quality, then immersion is improved, but data transmission requirements and network bandwidth increase
Solution Approach 1:
The VR image transmission is segmented into multiple components: base layer information transmitted to all users, and additional detail layers transmitted selectively based on user position and device capabilities. This segmentation allows the system to maintain high image quality where needed while reducing overall data transmission volume.
Solution Approach 2:
The system applies local quality enhancement by transmitting high-resolution data only for the specific region of the VR image that corresponds to the user's current field of view, while using lower resolution for peripheral areas. This ensures immersion is maintained in the critical viewing area without unnecessarily increasing overall data transmission.
3Adaptability or versatility
If motion information from multiple display devices is processed to synchronize VR experiences, then interaction among users is improved, but system complexity increases
Solution Approach 1:
The server acts as an intermediary that centralizes the complex task of processing motion information from multiple display devices. Instead of each device needing to directly communicate and synchronize with every other device, they all send motion data to the server, which processes it and distributes synchronized VR images, thereby reducing overall system complexity.
Solution Approach 2:
The server implements a universal processing platform that handles multiple functions: receiving motion information from various display devices, predicting user motion, rendering VR images, applying error correction, and distributing content to multiple users simultaneously. This multi-functionality reduces the need for separate specialized systems for each function.
