Audio System Location-Based Adaptation for Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of wearable devices, such as artificial reality headsets, face complexity in customizing audio presentation for different locations, requiring manual input adjustments to account for varying acoustic properties, which increases user interaction and complexity.
Innovation Solution
The method involves obtaining data on the local area using sensors, determining the location, and modifying audio content based on stored user preferences and acoustic parameters associated with that location, automatically updating audio presentation without manual user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of audio parameters is used for different locations, then audio presentation can be tailored to local acoustic properties, but user interaction and system complexity increase
Solution Approach 1:
The system automatically detects the user's location using sensors (GPS, Wi-Fi, Bluetooth) and retrieves pre-configured audio parameters for that location without requiring manual user input. The wearable device self-adjusts audio presentation based on stored location profiles, eliminating the need for users to manually configure audio settings for different environments.
Solution Approach 2:
Audio parameters for various locations are pre-configured and stored in the wearable device before the user arrives at those locations. When the user enters a new location, the system has already prepared the appropriate audio settings in advance, allowing for immediate adaptation without requiring real-time manual configuration.
2Adaptability or versatility
If manual configuration of audio parameters is performed for each location, then audio can be optimized for local acoustic properties, but the amount of user interaction increases
Solution Approach 1:
The system automatically detects the user's location using sensors (GPS, Wi-Fi, Bluetooth) and retrieves pre-configured audio parameters for that location without requiring manual user input. The wearable device self-adjusts audio presentation based on stored location profiles, eliminating the need for users to manually configure audio settings for different environments.

AI summary
An audio system customizes presentation of audio content to a user based on a location of the user. The audio system may be integrated into a headset or another wearable device. The audio system includes a position sensor, a sensor array, a transducer array, and an audio controller. The audio controller determines a location of the headset from the position sensor. Based on the determined location and a model, the audio controller retrieves one or more audio parameters for the location. The controller updates parameters of one or more audio functions (e.g., noise suppression, beamforming, what audio is streamed, etc.) based on the audio parameters determined for the location. Active or passive feedback from the user may be used to update the model.
