Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience unsmooth VR experiences due to poor wireless communication quality and heavily loaded render processes, which are often misattributed to the VR device or application rather than environmental factors.
Innovation Solution
A method for visualizing rendering performance that involves a server receiving poses and smoothness statuses from client devices and outputting a rendering performance map with directional smoothness indicators, allowing users and administrators to identify regions with poor communication quality and loaded render processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote rendering is used to enable low-end VR devices to experience high-quality VR content, then device accessibility and VR experience quality are improved, but wireless communication quality and rendering process load become critical factors affecting smoothness
Solution Approach 1:
The patent introduces a rendering performance map as an intermediary visualization tool that mediates between the complex rendering process and user perception. This map translates technical metrics (frame rates, latency, smoothness) into an intuitive visual representation, allowing users to understand performance issues without directly experiencing the underlying communication and rendering complexities.
Solution Approach 2:
The system implements feedback by continuously monitoring rendering performance metrics and updating the visualization map in real-time. This feedback loop allows users to see the direct impact of their movements and environmental factors on rendering quality, enabling them to adjust their behavior or environment to maintain smooth VR experiences.
2Measurement precision
If users experience unsmooth VR performance, then user satisfaction decreases, but the root cause (poor wireless communication or heavy render load) remains undetected and misattributed to device quality
Solution Approach 1:
The patent uses color changes in the rendering performance map to encode different performance states and their causes. Different colors represent different levels of smoothness and can indicate whether the primary bottleneck is wireless communication or rendering load. This visual encoding allows users to quickly diagnose performance issues without losing information about the root cause.
Solution Approach 2:
The system segments the performance diagnostic information into distinct visual components within the map. Separate visual indicators represent different performance metrics (frame rate, latency, smoothness) and their respective causes (communication quality, rendering load). This segmentation prevents information loss by presenting detailed diagnostic data in an organized, easily interpretable format.
3Measurement precision
If rendering performance map with detailed directional smoothness indicators is generated, then performance visualization accuracy is improved, but system complexity and data processing requirements increase
Solution Approach 1:
The patent adds a spatial dimension to performance visualization by creating a directional smoothness map that shows performance characteristics in different directions around the user's position. This dimensional transformation allows the system to process complex multi-directional performance data through a structured spatial framework, making high-precision visualization more computationally manageable.
Solution Approach 2:
The system applies local quality by generating directional smoothness indicators specific to different regions and directions in the VR environment. Rather than computing a single global performance metric, the server calculates localized performance characteristics for different spatial zones, allowing for more accurate visualization while reducing overall computational complexity through localized processing.
