Wearable Audio Volume Adjustment via Gaze Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable electronic devices lack the ability to dynamically adjust sound volumes based on the user's gaze direction and device orientation, leading to an inconsistent and less immersive user experience.
Innovation Solution
A wearable electronic device equipped with sensors to track the user's gaze and device orientation, which adjusts the sound volumes of content displayed in virtual areas accordingly, ensuring that sounds are louder when the user's gaze is directed towards them and softer when diverted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wearable electronic device outputs sound at a constant volume regardless of gaze direction, then the device structure remains simple, but the user experience becomes inconsistent and less immersive
Solution Approach 1:
The patent implements dynamic volume adjustment by continuously monitoring gaze direction through sensors and adjusting sound volume in real-time based on where the user is looking. The volume changes dynamically as the user moves their gaze between different virtual content areas, creating an adaptive audio experience that responds to user attention.
Solution Approach 2:
The system employs feedback mechanisms by using sensors to detect gaze direction and using this information to adjust sound volume accordingly. The detected gaze position feeds back to the audio output system, which modifies volume levels to match user attention, creating a closed-loop adaptive experience.
2Reliability
If the wearable electronic device adjusts sound volume dynamically based on gaze direction, then the user experience becomes more immersive, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a unified system: the sensor module serves both for gaze tracking and for determining device orientation, while the processor coordinates both visual and audio output adjustments. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The system automatically adjusts audio volume based on detected gaze direction without requiring manual user intervention. The device self-regulates the audio experience by monitoring its own operational state (gaze position) and making appropriate adjustments to sound output accordingly.
3Measurement precision
If the wearable electronic device uses multiple sensors to track gaze and orientation, then the precision of gaze detection improves, but the device complexity and energy consumption increase
Solution Approach 1:
The patent combines multiple sensing functions into an integrated sensor system that simultaneously tracks both gaze direction and device orientation. By merging these detection capabilities into a coordinated system, the device achieves high measurement precision while avoiding the energy waste of running separate independent sensing systems.

AI summary
A method for operating a wearable electronic device, includes: displaying first content in a first virtual area, which corresponds to a first direction with respect to the wearable electronic device; displaying second content in a second virtual area, which corresponds to a second direction with respect to the wearable electronic device; based on identifying that a gaze of a user wearing the wearable electronic device is directed toward the first direction, outputting a first sound of the first content at a first volume and a second sound of the second content at a second volume, wherein the first volume is different from the second volume; and based on identifying that the gaze of the user moves from the first direction to the second direction, outputting the first sound at a third volume different from the first volume and the second sound at a fourth volume different from the second volume.
