Vehicle Audio Source Selection via Verbal Request Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle computing systems, verbal commands for audio playback from remote devices may not be accurately interpreted, leading to issues with selecting the correct audio source for incoming audio, as the system may not recognize the audio output request and potentially result in failure to change the source appropriately.
Innovation Solution
A processor-based system that receives verbal requests for audio playback, relays commands to remote devices, selects the appropriate source channel, and receives incoming audio for playback, ensuring seamless integration and correct source selection through dialogue between the vehicle computing system and the remote device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the vehicle computing system acts as a mere passthrough for verbal commands, then the system complexity is reduced, but the system cannot comprehend the nature of the passed through command and cannot know that incoming audio will be present
Solution Approach 1:
The vehicle computing system acts as an intermediary between the remote device and the audio output system. It receives the audio playback request, interprets it as an incoming audio event, and proactively manages the audio source selection and routing. This mediator role allows the system to maintain relatively simple architecture while still comprehending the nature of commands and anticipating audio input requirements.
2Ease of operation
If the system does not proactively manage audio source selection, then the ease of operation is improved, but the audio source may not be changed appropriately when audio playback is requested
Solution Approach 1:
The system performs preliminary action by proactively selecting the audio source and preparing the audio output system before the actual audio playback begins. When the vehicle computing system receives an audio playback request, it anticipates the incoming audio and pre-configures the audio routing, ensuring the correct source is selected and the system is ready to receive audio without requiring manual user intervention.
3Device complexity
If the system waits for manual source selection, then the device complexity is reduced, but the audio playback may fail to begin properly when the system is not ready to receive audio
Solution Approach 1:
The system implements feedback by monitoring the audio playback request and the state of the audio output system. When audio playback is requested, the vehicle computing system receives feedback about the current audio source configuration and proactively adjusts the source selection to ensure the system is ready to receive audio. This feedback mechanism ensures reliable audio playback without requiring complex manual configuration.
Data Source
AI summary
A system includes a processor configured to receive a verbal request to active an audio playback application on a remote device wirelessly connected to the processor. The processor is also configured to relay the request to the remote device for handling. The processor is further configured to receive a request from the remote device for audio playback. The processor is also configured to select a source channel for incoming audio. The processor is additionally configured to receive incoming audio from the remote device over the selected source channel and playback the incoming audio over a vehicle output.
