Vehicle Controller Multi-Source Music Search and Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems in vehicles cannot replay music pieces requested by users if the desired music is not stored within the system, leading to unplayable situations.
Innovation Solution
An information processing device with a controller that acquires user utterances, searches for and replays music pieces across multiple sound sources, prioritizing local storage devices and free services to increase the likelihood of finding and playing the requested music.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the navigation system only stores music pieces locally, then the system structure remains simple, but the ability to replay requested music pieces is limited and may become unplayable
Solution Approach 1:
The navigation system is designed to handle multiple types of sound sources (local storage devices, wireless communication, subscription services) through a unified search and playback control mechanism. This multi-functional approach allows the system to replay music pieces from various sources without requiring separate dedicated systems for each source type, thereby improving reliability while controlling complexity.
Solution Approach 2:
The controller acts as an intermediary that manages the search and playback coordination between the user's music requests and multiple available sound sources. It mediates the complexity by providing a centralized control function that handles source selection, search coordination, and playback control, allowing diverse sound sources to be integrated without proportionally increasing system complexity.
2Productivity
If the system searches all sound sources randomly, then the search process is simple, but the efficiency of finding requested music pieces is reduced
Solution Approach 1:
The system pre-establishes a priority order for searching different sound sources based on user preferences and usage patterns. Before the actual search begins, the controller is configured with predetermined search priorities (e.g., local storage devices first, then wireless sources, then subscription services), allowing efficient sequential searching without requiring complex real-time decision-making during the search process.
Solution Approach 2:
The search control mechanism dynamically adjusts the search priority order based on user behavior patterns and preferences. The system learns from user interactions and adapts the search sequence to optimize finding requested music pieces, making the search process more efficient over time while managing complexity through automated adaptation rather than manual reconfiguration.
3Adaptability or versatility
If the system switches sound sources frequently, then more music pieces become available, but user discomfort increases due to frequent source changes
Solution Approach 1:
The system pre-configures sound source priorities based on user preferences and usage patterns before playback begins. By establishing a predetermined search and playback sequence in advance, the system can access music from multiple sources while minimizing frequent switches during playback, as the priority order guides a smooth, predictable transition process that maintains user comfort.
Data Source
AI summary
An information processing device includes a controller. The controller is configured to execute acquiring an utterance of a user, searching for a first music piece on a plurality of sound sources in response to the utterance of the user including a request to replay the first music piece, and replaying the first music piece that has been searched for and is provided in a first sound source.
