Head Mounted Display Directional Audio Output Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays (HMDs) lack the ability to effectively output audio signals from external digital devices in a manner that simulates the directional source of the sound, leading to a less immersive user experience and interference between multiple audio sources.
Innovation Solution
The HMD includes a processor, audio output units, and sensors to detect and control audio signals from external devices based on their location relative to the user, allowing for directional audio output and adjusting levels accordingly, thereby enhancing the immersive experience by simulating 3D audio based on device location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the HMD outputs audio signals from all connected external digital devices, then the user receives comprehensive audio information, but multiple audio sources interfere with each other and the user cannot focus on specific devices
Solution Approach 1:
The patent applies local quality by differentiating audio output based on device location. Audio signals from devices within the view angle are output with higher priority and volume, while devices outside the view angle are output with lower priority or muted. This creates spatially differentiated audio quality that helps users focus on relevant devices while reducing interference from others.
2Device complexity
If the HMD provides audio output without directional consideration, then the system is simple, but the user experience lacks immersion and realism
Solution Approach 1:
The patent implements dynamics by making the audio output characteristics change dynamically based on the relative position between the HMD and external devices. As devices move in or out of the view angle, their audio output priority and volume adjust automatically. This dynamic adaptation enhances audio realism without requiring complex manual configuration.
3Ease of operation
If the HMD prioritizes audio from devices within view angle, then the user can focus on relevant devices, but devices outside the view angle become inaccessible
Solution Approach 1:
The patent applies partial action by selectively prioritizing audio output for devices within the view angle rather than completely excluding devices outside the view angle. Audio from devices outside the view angle can still be output at reduced volume or priority, allowing users to access them when needed while maintaining focus on primary devices during normal operation.
