Distributed Audio Interface for Vehicle Dynamic Sound Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automotive reactive music systems primarily rely on a centralized user interface, limiting user interaction and failing to provide mechanisms for engaging with audio signals without driver distraction or additional interface usage.
Innovation Solution
A system that allows multiple interfaces on portable devices to receive vehicle characteristic data and user input, processing this information to generate and modify audio dynamically, enabling users to influence the audio experience without using the main vehicle interface or causing driver distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized user interface is used for audio control, then system complexity is reduced, but user interaction capability is limited
Solution Approach 1:
The system divides the user interface into multiple independent interfaces distributed across different portable devices (driver device, passenger devices). Each device can independently interact with the audio generation system, allowing simultaneous multiple user interactions without requiring a single centralized control point.
Solution Approach 2:
The system transitions from a single-dimension centralized interface to a multi-dimensional distributed interface architecture. Multiple portable devices operate in parallel, each providing its own interaction dimension, thereby expanding the system's adaptability while maintaining manageable complexity through modular design.
2Adaptability or versatility
If multiple portable device interfaces are implemented, then user interaction capability is enhanced, but device complexity increases
Solution Approach 1:
The audio generation system is designed to universally accept input from multiple types of portable devices (smartphones, tablets, wearables) through standardized communication protocols. Each device type leverages its existing capabilities while the system provides unified audio processing, reducing the need for device-specific complexity.
Solution Approach 2:
The system introduces a central audio processing unit that acts as an intermediary between multiple portable devices and the audio output system. This mediator handles the complexity of coordinating multiple inputs, processing audio signals, and managing device communication, thereby shielding individual devices from system-level complexity while enabling enhanced user interaction.
3Object-affected harmful factors
If passenger devices are used for audio control, then driver distraction is avoided, but access to audio controls becomes more difficult
Solution Approach 1:
The audio control interface is extracted from the traditional vehicle center console and relocated to portable devices carried by users. This extraction allows passengers to naturally access controls without requiring driver intervention, while the driver's device provides accessible controls within reach, eliminating the need to reach for the center console.
Solution Approach 2:
Each user interacts with audio controls through their own portable device, providing self-service audio control. The driver uses their device for controls within easy reach, while passengers use their devices independently, eliminating the need for either party to access the central console and reducing driver distraction while maintaining ease of operation.
Data Source
AI summary
Apparatus, system and method for generating and reproducing audio, were vehicle data, representing a vehicle characteristic, is produced and transmitted to a portable processing device communicatively coupled to a vehicle. The vehicle data is processed to determine a vehicle state and an audio generation application is invoked based on the determined vehicle state. The portable processing device receives user inputs representing physical inputs/manipulation, wherein audio is generated based on the user inputs. The portable processing device may be communicatively coupled to other portable devices, wherein user inputs from the other portable devices generate and/or modify audio.
