In-Vehicle Meeting Audio Selection for Noise-Free Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to account for user intent when recording and reproducing sounds from vehicle functions during electronic meetings, leading to unwanted noise interference.
Innovation Solution
An information processing device that includes a processing unit for sound processing, a reception unit for user input, and a processing control unit to execute sound processing based on user selection, distinguishing between meeting sounds and vehicle function sounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all sounds in the mobile body are recorded during electronic meetings, then complete audio documentation is achieved, but unwanted noise from vehicle functions interferes with meeting audio quality
Solution Approach 1:
The patent segments audio sources into two distinct categories: electronic meeting sounds and vehicle function sounds. The processing unit classifies and separates these sound types, allowing selective recording of only meeting-related audio while excluding vehicle function noises such as navigation prompts and warning sounds. This segmentation resolves the contradiction by enabling complete meeting documentation without incorporating interfering vehicle noises.
2Object-affected harmful factors
If external sound from vehicle functions is excluded from recording, then meeting audio quality is improved, but user-intended sounds may be accidentally omitted
Solution Approach 1:
The patent implements a feedback mechanism where the processing unit provides the user with a list of detected external sounds before finalizing the recording selection. The user can review and confirm which vehicle function sounds should be excluded, ensuring that genuinely intended sounds are not accidentally omitted. This feedback loop resolves the contradiction by maintaining audio quality while preserving user-intended sounds through user confirmation.
3Productivity
If automatic sound classification is implemented, then processing efficiency is improved, but user control over sound selection is reduced
Solution Approach 1:
The patent implements a dynamic system that adapts to user preferences. The processing unit automatically classifies sounds based on learned user patterns from previous interactions, but allows users to override and adjust classifications as needed. This dynamic approach resolves the contradiction by providing efficient automatic processing while maintaining user control through override capabilities and preference learning.

AI summary
An information processing device includes: a processing unit that executes sound processing, the sound processing including at least one of recording electronic meeting information and reproducing the recorded electronic meeting information, the electronic meeting information including sound of an electronic meeting in which a user boarding a mobile body participates; a reception unit that accepts selection of whether or not to set external sound as a target of the sound processing by the preprocessing unit, the external sound being output in the mobile body based on a function different from a function of the electronic meeting; and a processing control unit that causes the processing unit to execute the sound processing in accordance with the selection accepted by the reception unit.
