Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for adjusting virtual face models in virtual image social applications are cumbersome and complex, leading to a poor user experience due to tedious operation steps.
Innovation Solution
A method and apparatus that identify a real human face in a reality scene to create a virtual face model, allowing users to adjust key points through a face-pinching operation, determining the adjustment manner, and modifying the virtual face model accordingly, thereby simplifying the adjustment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional key point clicking and pulling method is used to adjust virtual face model, then facial features and face shape can be modified, but the operation steps become complicated and tedious
Solution Approach 1:
The patent replaces the mechanical interaction method of clicking and pulling key points with a gesture-based pinching operation. The pinching gesture, detected through touch screen technology, substitutes the complex multi-step mechanical interaction with a single intuitive gesture, thereby reducing operational complexity while maintaining adjustment functionality.
Solution Approach 2:
The patent changes the operational parameters from discrete key point manipulation to continuous gesture-based control. By detecting the pinching gesture's position, duration, and intensity, the system translates these parameter variations into corresponding face model adjustments, creating a more natural and less tedious interaction paradigm.
2Adaptability or versatility
If multiple key points are clicked and pulled to adjust facial features, then detailed customization is achieved, but user experience deteriorates due to tedious steps
Solution Approach 1:
The system performs preliminary actions by pre-defining multiple key points across the face model that correspond to different facial features. When a pinching gesture is detected, the system automatically identifies which pre-defined key points are involved and applies the appropriate adjustments, eliminating the need for users to manually select and manipulate each key point individually.
Solution Approach 2:
The pinching gesture serves multiple functions simultaneously: it selects key points, determines adjustment direction, controls adjustment magnitude, and triggers the modification process. This multi-functional gesture replaces the sequence of separate operations (selection, dragging, releasing) required in traditional methods, thereby reducing time loss while maintaining customization versatility.

AI summary
The present disclosure provides a method and apparatus for adjusting a virtual face model, an electronic device and a storage medium, so as at least to solve the technical problems of tedious operation steps and poor user experience of conventional solutions for adjusting a virtual image. A specific implementation solution includes: a real human face in a reality scene is identified to obtain a first virtual face model of the real human face in a virtual scene; in response to a face-pinching operation acting on the real human face, the face-pinching operation is identified to determine at least one to-be-adjusted key point in the first virtual face model and an adjustment manner of the at least one to-be-adjusted key point; and the first virtual face model is adjusted to a second virtual face model based on the adjustment manner of the at least one to-be-adjusted key point.
