Audio Signal Adjustment for AR Visual Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices providing augmented reality (AR), virtual reality (VR), and mixed reality (MR) services lack the ability to dynamically adjust audio signals based on the visual objects displayed, leading to an inconsistent user experience due to the absence of real-time acoustic signal processing and spatial audio rendering.
Innovation Solution
An electronic device equipped with a microphone array and a processor that receives acoustic signals, processes them to obtain information about signal propagation characteristics, and adjusts audio signals accordingly to synchronize with visual objects displayed, enhancing the user experience by providing a more immersive audio-visual experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio signals are not adjusted based on visual objects, then device complexity is reduced, but user experience consistency deteriorates
Solution Approach 1:
The system performs preliminary actions by obtaining propagation characteristics of acoustic signals in the space before displaying visual objects. This pre-processing allows the audio signal to be adjusted in advance based on the spatial environment, ensuring consistent user experience without adding complex real-time processing during visual object display.
Solution Approach 2:
The system uses feedback mechanisms by continuously monitoring the relationship between visual object positions and audio signal characteristics. The processor adjusts audio signals based on feedback from visual object display information and acoustic propagation characteristics, creating a closed-loop system that maintains user experience consistency.
2Measurement precision
If real-time acoustic signal processing is implemented, then audio-visual synchronization is improved, but processing time increases
Solution Approach 1:
The system obtains propagation characteristics of acoustic signals in advance, before real-time processing is needed. This preliminary characterization of the acoustic environment allows for faster real-time adjustments since the spatial properties are already known and stored for quick reference during visual object display.
3Reliability
If spatial audio rendering is added, then immersive experience is enhanced, but device complexity increases
Solution Approach 1:
The audio processing system is segmented into distinct functional modules: propagation characteristic acquisition, visual object position detection, audio signal adjustment, and output. This segmentation allows each module to be optimized independently and simplifies the overall system architecture while maintaining immersive experience quality.
