Dynamic VR Camera and Selective Video Quality for Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality (VR) technologies fail to provide an immersive and comfortable experience for watching live events due to limitations in depth perception and motion sickness, especially when viewers tilt their heads or move around, as they rely on fixed camera setups and pure video formats.
Innovation Solution
The system combines high-quality, view-dependent, three-dimensional models with full-motion video feeds, using sensors to detect user movements and adjust the virtual environment, allowing for dynamic area determination and overlaying 3D models within a virtual environment, while using high-resolution video for proximate objects and lower-resolution video for distant objects to enhance immersion and reduce disorientation.

Engineering Contradiction Analysis
1Measurement precision
If stereoscopic video with fixed cameras is used to improve depth perception, then depth perception is enhanced, but the experience becomes uncomfortable and causes motion sickness when users move their heads
Solution Approach 1:
The patent applies dynamics by transitioning from fixed cameras to dynamic virtual camera positions that automatically adjust based on user head movements. Sensors detect user orientation and the system dynamically repositions virtual cameras to maintain proper stereoscopic alignment, preventing image separation and motion sickness while preserving depth perception.
Solution Approach 2:
The system uses feedback from sensors that detect user head position and orientation to continuously adjust the virtual camera positions and video feed composition. This closed-loop feedback ensures the stereoscopic images remain properly aligned with the user's viewpoint, eliminating the swimming effect and discomfort associated with fixed-camera VR.
2Measurement precision
If high-resolution video is used for all areas to maintain quality, then video quality is improved, but spectrum efficiency decreases and bandwidth requirements increase
Solution Approach 1:
The patent applies local quality by differentiating video resolution requirements across different spatial areas. High-resolution video is applied only to the central area of interest where users naturally focus, while peripheral areas use lower resolution. This selective quality distribution maintains user experience while significantly reducing overall bandwidth consumption.
Solution Approach 2:
The system applies partial action by providing high-quality video only where necessary (central viewing area) rather than uniformly across the entire field of view. This selective approach delivers sufficient quality for the critical viewing zone while accepting reduced quality in less important peripheral regions, optimizing the quality-bandwidth tradeoff.

AI summary
An immersive virtual reality experience is provided. A plurality of areas within a virtual environment are determined. The plurality of areas includes at least a first area and a second area. A plurality of videos associated with the virtual environment are presented. The plurality of videos include a first video associated with the first area and a second video associated with the second area. The first video has a first quality, and the second video has a second quality lower than the first quality. A three-dimensional model of a first object is overlaid in the virtual environment.
