Hearable Mode Switching Based on Vehicle Drive Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearable devices struggle to balance noise cancellation and ambient sound awareness, particularly in vehicle environments, where users may not always be actively driving, leading to degraded usability and potential safety issues.
Innovation Solution
An information processing device that determines the vehicle's drive mode (automatic or manual) and adjusts the hearable device's operation mode accordingly, switching to ambient mode when the user is driving manually and noise cancellation mode when the vehicle is in autonomous drive, while also detecting emergency situations to ensure external sound awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the hearable device is set to noise cancelling mode to improve comfort during autonomous driving, then external sound awareness deteriorates, but if set to ambient mode to improve external sound awareness, then noise cancellation performance deteriorates
Solution Approach 1:
The hearable device dynamically switches between noise cancelling mode and ambient mode based on the vehicle's driving mode. When autonomous driving is detected, the device activates noise cancelling mode for comfort. When manual driving is detected, it switches to ambient mode for safety awareness. This dynamic adaptation resolves the contradiction by making the noise cancellation characteristic variable rather than fixed.
Solution Approach 2:
The device changes the noise processing parameter (noise cancellation level) based on driving conditions. The controller receives driving mode information from the vehicle and adjusts the hearable device's operation accordingly, transforming the static noise cancellation parameter into a dynamic one that adapts to external conditions.
2Reliability
If the hearable device automatically switches to ambient mode when the user boards the vehicle to ensure safety, then usability for non-driving situations deteriorates
Solution Approach 1:
The system implements feedback by continuously monitoring the vehicle's driving mode through the controller and adjusting the hearable device's operation accordingly. The controller receives real-time driving mode information and feeds it back to the hearable device, enabling automatic adaptation without user intervention while maintaining appropriate noise cancellation levels for each driving scenario.
3Ease of operation
If the hearable device maintains noise cancelling mode during manual driving to preserve comfort, then safety awareness deteriorates
Solution Approach 1:
The noise cancellation characteristic is made dynamic by linking it to the driving mode. The device automatically transitions from noise cancelling mode during autonomous driving to ambient mode during manual driving, ensuring that comfort is prioritized when appropriate while safety awareness is maintained when needed.

AI summary
The present disclosure provides a technology that can preferably improve the usability when a user wearing a hearable device boards a vehicle. In an information processing device according to the present disclosure, a controller obtains a drive mode of a vehicle in which a user wearing the hearable device rides. When the drive mode of the vehicle is an automatic drive mode, the controller permits the operation mode of the hearable device to be set to a first mode. On the other hand, when the drive mode of the vehicle is a manual drive mode and a user wearing a hearable device is a user performing a drive operation of the vehicle, the controller sets the operation mode of the hearable device to a second mode.
