Real-Time Audio Signal Adjustment for VR Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices cannot adjust audio signals in real-time, leading to a lack of immersion in experiences like virtual reality, where audio signals remain fixed despite changes in the virtual scene.
Innovation Solution
An information processing method that determines N channel signals in an audio signal and adjusts their output parameters based on the device type and user head gestures, ensuring the audio signals correspond to the sound source position, allowing for real-time adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio signals are predetermined for outputting via audio output device, then the device complexity is reduced and ease of operation is improved, but the adaptability deteriorates as audio signals cannot be adjusted in real-time when the virtual scene changes
Solution Approach 1:
The patent implements dynamic audio signal adjustment by detecting user head gestures and real-time video content changes, then automatically modifying audio output parameters accordingly. The system transitions from static predetermined audio signals to dynamic adaptive audio signals that respond to user actions and scene changes, resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The system establishes a feedback loop by detecting head gestures and video content changes, processing this information, and adjusting audio output parameters in response. This closed-loop control mechanism enables real-time audio adaptation while managing complexity through automated feedback-based adjustment rather than manual intervention
2Reliability
If audio signals are predetermined and fixed, then the ease of manufacture and operation are improved, but the user experience quality deteriorates as users cannot have an immersive experience while using virtual reality
Solution Approach 1:
The system performs self-service by automatically detecting video content changes and head gestures, then autonomously adjusting audio output parameters without requiring user intervention. This self-adjusting mechanism maintains reliable audio-visual synchronism while eliminating the need for manual operation, resolving the contradiction between reliability and ease of operation

AI summary
The present disclosure provides an information processing method and an electronic device. The method comprises: obtaining an audio signal in an output signal; determining N channel signals in the audio signal, where N is a positive integer; determining whether the audio signal needs to be adjusted or not; and adjusting, when the audio signal needs to be adjusted, an output parameter of at least one of the N channel signals respectively, and outputting the N adjusted channel signals via an audio output device, such that the N adjusted channel signals correspond to a sound source position of the audio signal. The above method according to the present disclosure can solve the technical problem that the audio signal cannot be adjusted in real time and achieve a technical effect of automatic adjustment of the audio signal.
