Personalized Audio Content System for Vehicle Infotainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current infotainment systems lack flexibility in personalizing content for vehicle users, as they are limited by predefined radio stations and content providers, making it difficult for drivers and passengers to access preferred music during trips, especially with the increasing number of digital radio channels, which can be distracting and manually intensive.
Innovation Solution
A personalized content system that generates a summary music identification value representing a user's musical taste, allowing for customized playlists by interpreting this value, which can be processed locally or remotely, enabling users to create or use pre-defined values to select music based on attributes like genre, style, and acoustic characteristics, reducing manual interaction and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If predefined radio stations and content providers are used, then the system structure is simple and stable, but the system lacks flexibility in personalizing content for users
Solution Approach 1:
The patent introduces a content provider as an intermediary between the infotainment system and multiple content sources (internet radio stations, local storage, remote servers). This intermediary manages the complexity of personalization by handling content aggregation, filtering, and delivery, allowing the system to offer customized content without requiring complex user-side implementation of personalization logic
Solution Approach 2:
The system segments content delivery into multiple independent sources (internet radio, local storage, remote servers) that are managed separately but can be combined through the content provider. This allows flexible personalization by selecting and combining content from different sources without requiring the entire system to be restructured
2Adaptability or versatility
If users manually select from numerous digital radio channels, then content variety increases, but user distraction and manual interaction increase
Solution Approach 1:
The system implements self-service through automated content selection based on user profiles and preferences. The content provider automatically filters, selects, and delivers appropriate content from multiple sources without requiring users to manually browse through numerous channels, thereby reducing distraction while maintaining content variety
Solution Approach 2:
User profiles and content preferences are established in advance through preliminary setup. The system pre-configures content filtering rules and source selections based on user preferences, so that during actual use, content is automatically delivered without requiring manual selection, reducing operational complexity and user distraction
3Extent of automation
If automated content selection is implemented, then user distraction is reduced, but system complexity increases
Solution Approach 1:
The content provider acts as an intermediary that centralizes the automation logic for content selection. By placing the complex automation rules, filtering algorithms, and source management in the content provider layer rather than in the core infotainment system, the patent achieves high automation while keeping the system control structure manageable and modular
Data Source
AI summary
The personalized content system of the system combines a summary music identification value creation and identification algorithm that represents a mathematical summary music identification of a song, an audio file, or other relational music criteria and data (e.g title, artist, genre, style, beats per minute, etc.) or any combination thereof. The derived value represents the musical taste or style attributes of a song or style. The user can control the system by issuing one of a plurality of commands comprising artist command, song/title command, genre command, and album/filtered list command. These commands then lead to command trees that may be used in a voice controlled system, for example.
