Solution Overview

Problem

Existing performance recording methods in virtual scenarios require manual replacement of performance costumes, leading to low efficiency and poor human-computer interaction.

Innovation Solution

Automatically replace performance costumes for virtual objects based on changes in background audio playback rhythms, associating different costumes with distinct rhythms to ensure synchronization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual replacement of performance costumes is used, then users can control costume changes, but replacement efficiency and human-computer interaction efficiency are low

Engineering Contradiction:

Improvecostume replacement efficiencyVSAvoidhuman-computer interaction efficiency

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system automatically replaces performance costumes by detecting changes in background audio playback rhythms, eliminating the need for manual user intervention. The electronic device monitors audio rhythm changes and autonomously switches costumes according to pre-established associations, making the system self-servicing in the costume replacement task.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical operation of selecting and switching costumes is replaced by an automated electronic system that detects audio rhythm changes and triggers costume replacements programmatically, substituting human manual interaction with an automated electronic control mechanism.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple performance costumes are combined manually, then costume variety is achieved, but the process is complex and time-consuming

Engineering Contradiction:

Improvecostume varietyVSAvoidcostume combination process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system pre-establishes associations between different playback rhythms and corresponding performance costumes before the performance recording begins. This preliminary configuration allows the system to automatically select and switch costumes based on detected audio rhythms during playback, eliminating the need for real-time manual combination and reducing operational complexity.

Inventive Principle:

Principle #10Preliminary action

AI summary

This application provides a method for playing a performance of a virtual object in a virtual scenario performed by an electronic device. The method includes: displaying a virtual object outfitted with a first performance costume in the virtual scenario; in response to a user operation for the virtual object, playing a first part of background audio and displaying a first performance action performed by the virtual object outfitted with the first performance costume corresponding to the first part of the background audio; and automatically replacing the first performance costume outfitted for the virtual object with a second performance costume outfitted for the virtual object in response to the background audio changing from the first part to a second part corresponding to the second performance costume.
