Solution Overview

Problem

Existing technologies fail to create a sound environment tailored to a user's state within a space, limiting the potential enhancement of comfort and intellectual productivity.

Innovation Solution

An information processing method that acquires user states related to factors like relaxation and concentration, selects appropriate sound contents based on these states, and reproduces them in the user's environment to form a customized sound environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If airflow is provided to control user arousal level, then user comfort is improved, but sound environment tailored to user state cannot be formed

Engineering Contradiction:

Improveuser comfortVSAvoidsound environment adaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts sound content selection based on real-time user state detection. The sound environment changes adaptively according to detected user states (relaxation, concentration, arousal levels), making the system versatile and responsive to different user conditions rather than static

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameters of sound content (type, volume, frequency) based on user state parameters. Different sound contents are selected by adjusting parameters according to detected user states, enabling tailored sound environments for different conditions

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If generic sound content is reproduced, then system complexity is reduced, but user-specific comfort and productivity enhancement is limited

Engineering Contradiction:

Improvesystem complexityVSAvoidintellectual productivity

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The system performs self-adjustment by automatically detecting user state and selecting appropriate sound content without manual intervention. The system serves itself by making autonomous decisions about sound environment configuration based on real-time user state monitoring

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements a feedback loop where user state is continuously detected and fed back to the sound content selection mechanism. This closed-loop control enables the system to adjust sound environment based on actual user response, enhancing productivity through personalized audio stimulation

Inventive Principle:

Principle #23Feedback

AI summary

An information processing device acquires a value of a factor with respect to each of a plurality of sound contents; acquires a user state that is a state of a user related to the factor; selects a sound content having a value of the factor according to the user state from the plurality of sound contents; and reproduces the selected sound content in a space where the user is present.
