Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In conventional voice control systems for virtual spaces, conversation in a conversation group is disrupted when voice from outside the group enters, making smooth conversation challenging.

Innovation Solution

A voice control system that includes a setting processing unit to establish conversation groups in a virtual space and a restriction processing unit to prevent voice output from outside the group to users within the group.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If voice output is allowed for all users in a virtual space, then users can communicate freely, but voice from outside the conversation group enters the group and disrupts smooth conversation

Engineering Contradiction:

Improvecommunication freedomVSAvoidvoice disruption

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments users into different conversation groups within the virtual space. Each group has its own voice output control mechanism, allowing voice to be output for users within the group while blocking voice from users outside the group. This segmentation resolves the contradiction by enabling selective communication freedom within groups while preventing harmful voice disruption from external users.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality control by differentiating voice output permissions based on user group membership. Users within the conversation group have permission to output voice, while users outside the group have their voice output blocked. This local differentiation allows communication freedom where needed while preventing disruption where it would be harmful.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If voice control is implemented to block external voices, then smooth conversation within groups is enabled, but system complexity increases

Engineering Contradiction:

Improvevoice disruptionVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements a voice control unit that serves multiple functions: it determines conversation groups, manages voice output permissions, and blocks external voices. By consolidating these functions into a single multi-functional unit, the system achieves effective voice control without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The voice control unit operates autonomously by automatically determining which users should have voice output blocked based on their group membership status. The system self-manages the voice control logic without requiring complex external intervention or manual configuration, thereby reducing operational complexity while maintaining effective voice disruption prevention.

Inventive Principle:

Principle #25Self-service

AI summary

A voice control system includes a setting processing unit that sets up a conversation group including a plurality of users in a virtual space, and a restriction processing unit that restricts an output of voice which is outside the conversation group to be set by the setting processing unit to a user in the conversation group.
