Solution Overview

Problem

Existing interaction technologies lack the ability to provide personalized and diverse interaction experiences across various scenarios, such as knowledge acquisition, customer service, and commemoration of relatives and friends, failing to meet users' increasing demands for intelligent and interactive experiences.

Innovation Solution

A virtual human-based interaction method and system that generates a virtual human based on character feature data, including expression and action features, to dynamically display personalized interactions on a display interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional interaction technology is used, then system simplicity is maintained, but interaction personalization and diversity are insufficient

Engineering Contradiction:

Improveinteraction personalizationVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates virtual human copies that replicate human appearance, behavior, and interaction patterns. These virtual human copies serve as personalized interaction interfaces, allowing users to engage with customized avatars that adapt to different scenarios and user preferences, thereby achieving interaction personalization without requiring complex system reconfiguration for each interaction type.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The virtual human copies are designed to be dynamic and adaptable rather than static. They can change their behavior, expression, and interaction style based on the scenario and user input, enabling the system to provide personalized interactions across diverse scenarios without manually designing each interaction pathway.

Inventive Principle:

Principle #15Dynamics

2Reliability

If basic virtual representation is used, then development resources are saved, but anthropomorphic interaction quality is insufficient

Engineering Contradiction:

Improveinteraction authenticityVSAvoidvirtual human generation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs parameter changes by adjusting multiple dimensions of the virtual human copies including appearance parameters, behavioral parameters, and interaction parameters. By dynamically modifying these parameters based on scenario requirements and user preferences, the system achieves high-quality anthropomorphic interactions while managing complexity through parameterized control rather than hard-coded scenarios.

Inventive Principle:

Principle #35Parameter changes
