Directional Headset Audio Control for Intuitive Turn Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle navigation systems fail to provide intuitive direction guidance, particularly for motorcycle riders using mobile terminals, as they do not account for the use of headsets for audio output, leading to potential distraction and deviation from the guidance route.
Innovation Solution
A communication device that controls left and right audio volumes of an audio output device worn by the user based on the guidance route, ensuring one volume is louder than the other to indicate turns, thereby enhancing intuitive understanding of directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional audio output methods are used without directional volume control, then the audio guidance is simple to implement, but the user cannot intuitively recognize turn directions
Solution Approach 1:
The patent applies asymmetry by controlling the left and right audio volumes differently based on the guidance route. When a right turn is upcoming, the right audio volume is increased relative to the left; when a left turn is upcoming, the left audio volume is increased relative to the right. This asymmetric volume distribution enables users to intuitively recognize turn directions through directional audio cues.
2Reliability
If audio guidance is provided through headset without directional control, then the device setup is simple, but the user may be distracted and deviate from the guidance route
Solution Approach 1:
The patent implements feedback by continuously monitoring the upcoming guidance route information and dynamically adjusting the audio volume distribution in real-time. The system receives route information, determines upcoming turns, and automatically adjusts left and right audio volumes accordingly, providing continuous directional feedback to keep the user on the correct route without causing distraction.

AI summary
A communication device comprising: a route acquisition unit configured to acquire information of a guidance route of a vehicle used by a user; and a control unit configured to cause an audio output device worn by the user to output audio while the vehicle is traveling on the guidance route, wherein the control unit controls left and right audio volumes of the audio in accordance with the guidance route.
