Vehicle Cabin Audio Feedback for Real-Time Singing Quality Rating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio signal output systems in vehicles do not provide a real-time quality rating of a person's performance while singing or accompanying a musical piece, which can distract the driver and are not feasible for providing feedback without visual distractions.
Innovation Solution
An apparatus comprising audio output and sensing devices, along with a processing unit, to generate and output an acoustically perceivable quality rating signal based on predefined criteria, allowing for real-time feedback without visual distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual feedback is provided for performance quality rating, then measurement precision is improved, but driver safety deteriorates due to distraction
Solution Approach 1:
The patent replaces visual feedback (mechanical/optical system) with acoustic feedback system. The performance quality rating is delivered through audio signals including tone-based feedback and superimposed audio messages, eliminating the need for visual displays that would distract the driver while maintaining measurement precision through acoustic signal processing.
2Productivity
If real-time quality rating feedback is provided, then productivity is improved, but device complexity increases
Solution Approach 1:
The audio output device serves multiple functions: it outputs the musical piece, provides tone-based quality feedback, and delivers superimposed audio messages. This multi-functionality allows real-time quality rating feedback without requiring separate dedicated hardware, thereby improving productivity while managing device complexity through versatile component utilization.
Solution Approach 2:
The system implements real-time feedback by continuously analyzing acoustic signals, comparing them against reference data, and immediately providing quality rating feedback through audio output. This closed-loop feedback mechanism enables real-time productivity improvement while the feedback is integrated into the existing audio processing pipeline, minimizing additional complexity.
3Object-affected harmful factors
If audio feedback is used for quality rating, then driver safety is improved, but information delivery effectiveness may worsen
Solution Approach 1:
The feedback information is segmented into distinct components: tone-based feedback for immediate quality assessment and separate superimposed audio messages for detailed guidance. This segmentation allows driver safety to be maintained through acoustic channels while preserving information delivery effectiveness by organizing content into manageable, clearly differentiated segments that are easier to process auditorily.
