Display Rotation Using Sound Direction for Viewpoint Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for rotating displayed visual information on devices often result in unintentional rotation errors, particularly when the device is tilted or capturing spatial audio, leading to misalignment with the user's viewpoint, especially in livestreaming scenarios.
Innovation Solution
An apparatus and method that determines the direction of arrival of sound from a sound source relative to a user device to control the angle of orientation of visual information displayed on a display, using audio signals to maintain alignment with the user's viewpoint, even when the device is tilted or rotated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device is tilted or rotated to capture spatial audio or take photos, then the field of view and audio capture capability are improved, but the visual information becomes misaligned with the user's viewpoint
Solution Approach 1:
The system continuously monitors the direction of arrival of sound sources and uses this feedback to dynamically adjust the rotation angle of displayed visual information, ensuring alignment with the user's viewpoint even when the device is tilted or rotated
Solution Approach 2:
Instead of relying on mechanical sensors alone to detect device orientation, the system substitutes acoustic field detection to determine spatial relationships, using sound direction data to control visual information rotation and achieve alignment without traditional mechanical orientation sensing
2Measurement precision
If traditional orientation detection methods are used, then the device can detect its physical orientation, but unintentional rotation errors occur when capturing spatial audio
Solution Approach 1:
The system introduces sound direction determination as an intermediary measurement that bridges the gap between device physical orientation and user's actual viewpoint, using acoustic signals as a mediator to accurately infer the intended viewing direction even when the device is tilted
Solution Approach 2:
The system separates orientation detection into independent functional components: acoustic signal capture, direction of arrival determination, and visual information rotation control, allowing each component to be optimized independently and reducing interference between spatial audio capture and visual alignment
