XR Display Frame-Rate Switching Based on User Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies lack flexibility in adjusting frame rate and resolution due to limitations in processing component performance, leading to suboptimal display quality in dynamic and static scenes.
Innovation Solution
An image processing and display method that dynamically adjusts frame rate and resolution based on user posture information, employing splicing and cropping techniques to achieve 'high frame rate, low resolution' and 'high resolution, low frame rate' modes, enhancing display flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the processing component processes images at high resolution, then manufacturing precision is improved, but productivity deteriorates due to limited processing performance
Solution Approach 1:
The patent applies dynamics by making the frame rate adjustable based on user posture. The display component dynamically switches between first frame rate (when posture reaches preset parameters) and second frame rate (when posture does not reach preset parameters), allowing the system to adapt processing productivity to actual display needs while maintaining high resolution capability
Solution Approach 2:
The patent changes the frame rate parameter based on posture detection results. When the user's posture reaches preset parameters, the system operates at first frame rate; when posture does not reach preset parameters, it switches to second frame rate. This parameter adjustment resolves the contradiction by allowing high frame rates only when necessary for high-quality display
2Productivity
If the processing component processes images at high frame rate, then productivity is improved, but manufacturing precision deteriorates due to processing limitations
Solution Approach 1:
The system dynamically adjusts frame rate based on posture detection. When posture reaches preset parameters, high frame rate is maintained to ensure smooth display. When posture does not reach preset parameters, the system can operate at lower frame rate, accepting reduced productivity to maintain processing quality and resolution
3Device complexity
If fixed frame rate is used, then device complexity is reduced, but adaptability deteriorates due to inability to adjust to different scenes
Solution Approach 1:
The patent implements feedback by detecting user posture and using this information to adjust frame rate. The display component receives posture information, determines whether preset parameters are reached, and accordingly adjusts between first and second frame rates. This feedback mechanism provides scene adaptability while maintaining relatively simple device architecture
Solution Approach 2:
The system transitions from fixed frame rate to dynamic frame rate adjustment based on posture detection. This dynamic adaptation allows the display to automatically adjust to different viewing conditions and scenes, significantly improving versatility without adding substantial complexity to the device

AI summary
Provided is an image display method. The image display method is applicable to a display component of an extended reality (XR) device further including a processing component. The image display method includes: receiving an image from the processing component; displaying the image from the processing component at a first frame rate in response to posture information of a user of the XR device reaching a preset parameter; and displaying the image from the processing component at a second frame rate in response to the posture information of the user of the XR device not reaching the preset parameter, the second frame rate being lower than the first frame rate.
