Solution Overview

Problem

Existing media playback systems require frequent manual adjustments of audio parameters like volume and equalization, disrupting the listener's experience due to varying preferences and environmental conditions, which can be uncomfortable and frustrating.

Innovation Solution

A media presentation system that uses real-time audio playback data from microphones and facial and body expression interpretation from cameras, combined with artificial intelligence, to automatically adjust audio parameters such as volume, equalization, and environmental settings like temperature and lighting based on audience feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual adjustments of audio parameters are required, then audio quality can be optimized for individual preferences, but listener experience is disrupted and listening comfort is reduced

Engineering Contradiction:
Improveaudio parameter optimizationVSAvoidlistening comfort
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system automatically adjusts audio parameters without requiring manual intervention from listeners. The media presentation system monitors audience feedback through sensors and cameras, processes this information to determine optimal audio settings, and executes adjustments autonomously, allowing the system to serve itself rather than requiring user interaction.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously collects feedback from the audience through sensors and cameras monitoring facial expressions, body language, and environmental conditions. This feedback loop enables the system to adapt audio parameters in real-time based on actual listener responses, creating a dynamic adjustment mechanism that optimizes audio quality while maintaining listening comfort.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If frequent manual adjustments are made, then audio parameters can be optimized, but the constant interaction frustrates the listener and detracts from the overall experience

Engineering Contradiction:
Improveaudio parameter adaptationVSAvoidlistener engagement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs self-adjustment of audio parameters based on automated analysis of audience feedback. Rather than requiring listeners to manually adjust settings, the system independently processes sensor data, determines optimal parameters, and executes adjustments, thereby maintaining adaptability while eliminating frustrating constant interaction.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces manual mechanical adjustments with automated electronic control. Physical interaction with volume knobs or remote controls is substituted by electronic sensors, processors, and actuators that automatically adjust audio parameters based on digital analysis of audience responses, thereby maintaining adaptability while improving listener engagement.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If automated adjustment is implemented, then listening comfort is improved, but device complexity increases due to sensors, cameras, and processing systems

Engineering Contradiction:
Improvelistening comfortVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system employs multi-functional components that serve multiple purposes. For example, cameras and sensors used for audience feedback monitoring also provide data for audio parameter optimization. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while maintaining improved listening comfort through automated adjustment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Automatic control of media presentation parameters is provided by using one or more of real-time audio playback measurement data from microphones and audience facial and body expression interpretation from video and infrared cameras, in conjunction with artificial intelligence for interpretation and evaluation of facial and body expression and predetermined perceptual audio models. Media presentation parameters can include, for example, speaker volume, audio equalization, feedback elimination, play/pause, and other audio content-related aspects of presentation. In some embodiments, additional environmental parameters can be modified to enhance audience experience, such as, for example, temperature, lighting, and the like, in response to audience facial and body expression.
