Remote Operation Terminal Audio Switching for Noise Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In noisy environments, remote operation robots used for sightseeing tours make it difficult for users to have clear conversations due to environmental sounds overpowering voices.
Innovation Solution
The system allows direct voice data exchange between remote operation terminals, enabling clear conversations by switching between inter-mobile-body and inter-terminal conversation modes, where environmental sounds are either mixed with or excluded from the voice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote operation robots are used in noisy environments for sightseeing tours, then users can experience realistic environmental sounds, but clear conversation between users becomes difficult due to environmental sounds overpowering voices
Solution Approach 1:
The patent segments the audio transmission path into two distinct channels: mobile-body-to-mobile-body communication (for realistic experience with environmental sounds) and terminal-to-terminal communication (for clear conversation without environmental noise). This segmentation allows users to switch between modes depending on whether they prioritize realism or clarity, resolving the contradiction between these two requirements.
2Adaptability or versatility
If sound pressure information from mobile body microphones is transmitted to remote terminals, then users experience realistic environmental sounds, but environmental noise interferes with clear voice communication
Solution Approach 1:
The patent introduces an intermediary communication mode where terminals can exchange sound pressure information directly with each other, bypassing the mobile body microphones that capture environmental noise. This intermediary path allows clear voice communication by mediating the audio transmission through a dedicated channel that excludes environmental sounds, while still preserving the option to use the original mobile body-to-mobile body path for immersive experiences.

AI summary
Each remote operation terminal includes an own robot sound pressure information transmission unit, an own robot sound pressure information reception unit, an another terminal sound pressure information transmission unit, an another terminal sound pressure information reception unit, a sound pressure information output unit configured to output sound pressure information received by the own robot sound pressure information reception unit or the other terminal sound pressure information reception unit, and a conversation control unit configured to execute an inter-robot conversation mode that establishes conversation with another user using the own robot sound pressure information transmission unit and the own robot sound pressure information reception unit and an inter-terminal conversation mode that establishes conversation with another user using the other terminal sound pressure information transmission unit and the other terminal sound pressure information reception unit in such a way that they can be switched.
