Solution Overview

Problem

Communication delays in interactive distribution services, such as remote live performances, cause timing shifts in user interactions, leading to a strange experience for users.

Innovation Solution

An information processing device that acquires communication delay information between terminal devices and adjusts interaction data distribution based on these delays, controlling volume and timing to synchronize user interactions with the live performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If interaction data is transmitted through network communication, then users can participate in live performance from remote locations, but communication delay causes timing shifts in user interactions making the experience strange

Engineering Contradiction:

Improveremote participation capabilityVSAvoidcommunication delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary measurement of communication delay between terminal devices before the live performance starts. This measured delay information is stored and used during the performance to adjust interaction data timing, ensuring that interactions are synchronized with the live performance despite network delays.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors and measures communication delay between terminal devices and uses this feedback information to dynamically adjust the timing of interaction data transmission. By incorporating the measured delay into the data control decisions, the system maintains synchronization between user interactions and live performance content.

Inventive Principle:

Principle #23Feedback

2Productivity

If interaction data from multiple terminal devices is processed, then user engagement is enhanced, but timing coordination becomes complex and difficult to manage

Engineering Contradiction:

Improveuser engagement levelVSAvoidtiming coordination complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system measures and processes communication delay information specifically for each terminal device individually. Each terminal device's delay characteristics are captured and used to adjust that specific device's interaction data timing. This localized approach simplifies the overall timing coordination by treating each device's synchronization requirements independently rather than attempting to coordinate all devices simultaneously.

AI summary

There is provided an information processing device that distributes live data to a first user (terminal device 301), the information processing device performing control related to interaction data from the first user on the basis of information of a delay between the first user that transmits the interaction data with respect to the live data and the information processing device, or a delay between a second user (terminal device 302) that receives the interaction data from the first user with respect to the live data and the first user.
