Solution Overview

Problem

Users of spatial audio systems often experience confusion and negative user experiences due to a lack of feedback when adjusting audio focus parameters, leading to mistaken assumptions about the functionality of audio focus features.

Innovation Solution

An apparatus and method that receive captured spatial audio information and allow users to set audio parameters, determining whether the set value meets certain criteria, and adjusting the audio parameter accordingly, providing perceivable feedback to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If audio focus parameters are adjusted without providing feedback, then the system operation is simple, but user understanding and satisfaction deteriorate

Engineering Contradiction:
Improveaudio parameter adjustmentVSAvoiduser feedback information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent implements feedback by detecting whether an audio parameter adjustment was successful and providing this information to the user. The system determines if the adjusted parameter meets criteria (such as being within a valid range or achieving the intended audio focus effect) and communicates this status to the user, thereby resolving the information loss problem while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

2Device complexity

If no feedback is provided for audio parameter adjustments, then the system complexity is low, but user experience deteriorates

Engineering Contradiction:
Improvefeedback mechanismVSAvoiduser experience
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system provides feedback about the success of audio parameter adjustments to improve user experience reliability. By implementing a feedback mechanism that communicates whether parameter changes were successful, the system builds user trust and reduces confusion without requiring overly complex additional hardware or processing infrastructure.

Inventive Principle:
Principle #23Feedback

3Speed

If audio parameter values are set without validation, then the operation speed is fast, but the reliability of audio focus functionality deteriorates

Engineering Contradiction:
Improveparameter setting speedVSAvoidaudio focus functionality
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs preliminary validation of audio parameter values before applying them. By checking whether proposed parameter changes meet specified criteria (such as valid ranges or logical consistency) before execution, the system ensures reliable audio focus functionality while maintaining fast operation through efficient validation techniques.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides immediate feedback to users about whether their parameter adjustments are valid and were successfully applied. This feedback mechanism confirms reliable functionality execution while maintaining user-friendly speed by providing instant confirmation without requiring lengthy validation processes.

Inventive Principle:
Principle #23Feedback
