Solution Overview

Problem

Existing audio services fail to effectively convey audio information from one user to another when the listener's situation differs from the original recorder's situation, leading to a lack of understanding and ineffective information sharing.

Innovation Solution

An information processing system that receives and outputs audio information based on the positional and directional data of both users, ensuring that the audio is played when the users are within a predetermined distance and facing similar directions, thus replicating the original recording scenario.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If audio information is output to a second user based solely on position matching, then the system complexity is reduced, but the understanding effectiveness deteriorates because the listener's situation may differ from the recorder's situation

Engineering Contradiction:
Improvesystem complexityVSAvoidunderstanding effectiveness
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The system performs preliminary analysis by acquiring and storing direction information at the time of audio recording. This preliminary action enables later comparison between the recorder's direction and the listener's direction, ensuring that audio is only output when both position and directional conditions are met, thereby preserving understanding effectiveness without excessive complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the audio output decision by continuously comparing both position and direction parameters. Instead of using a static position-only threshold, the system evaluates the directional relationship between the recorder and listener in real-time, making the output condition adaptive to the spatial context and improving understanding effectiveness

Inventive Principle:
Principle #15Dynamics

2Loss of information

If the system acquires and compares direction information between recorder and listener, then the understanding effectiveness is improved, but the device complexity increases due to additional sensors and processing

Engineering Contradiction:
Improveunderstanding effectivenessVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system uses the existing position information infrastructure to serve multiple functions. The same position data that determines spatial relationship also forms the basis for directional comparison, allowing the system to evaluate both position and direction using a unified data source and reducing the need for separate directional sensors

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

Solution Approach 2:

The system introduces direction information as an intermediary parameter that mediates between position data and audio output decisions. This intermediary enables the system to evaluate the spatial context more accurately by considering the directional relationship between recorder and listener, improving understanding effectiveness while maintaining manageable complexity through a clear decision hierarchy

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If audio information is registered without considering directional alignment, then the ease of operation is improved, but the information sharing effectiveness deteriorates

Engineering Contradiction:
Improveregistration easeVSAvoidinformation sharing effectiveness
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system performs preliminary acquisition of direction information at the time of audio registration, storing this data alongside the audio content. This preliminary action occurs automatically during the registration process without requiring additional user operations, maintaining ease of operation while enabling later directional comparison to ensure effective information sharing

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically handles the directional analysis and comparison processes without requiring user intervention. The directional relationship between recorder and listener is evaluated automatically when audio output is considered, allowing the system to self-regulate the audio output based on spatial context while keeping the registration process simple and user-friendly

Inventive Principle:
Principle #25Self-service
