Posture-Based Virtual Object Control Without Screen Touch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling virtual objects on smart terminals, such as smartphones and smart tablets, are inconvenient and lack engagement as they primarily rely on screen touch interactions.
Innovation Solution
A method and apparatus that utilize user posture information to control virtual objects, eliminating the need for screen touch by matching preset postures to control the movement of virtual objects and generate results based on contact conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen touch control is used to control virtual objects, then the control method is simple to implement, but the convenience and user engagement are poor
Solution Approach 1:
The patent replaces the mechanical screen touch interaction system with a posture recognition system that uses camera imaging and image processing to detect user postures and control virtual objects, thereby improving convenience and engagement without requiring physical contact with the device
Solution Approach 2:
The patent introduces an intermediary posture recognition system between the user and the virtual object control. The system uses camera imaging to capture user postures, processes the images to recognize specific postures, and translates these postures into control commands for virtual objects, thereby enhancing user experience
2Adaptability or versatility
If posture recognition is implemented to control virtual objects, then user engagement and convenience are improved, but the system complexity increases
Solution Approach 1:
The patent makes the existing camera and processing units perform multiple functions: they not only capture images for display but also recognize user postures and generate control commands for virtual objects. This allows posture-based control to be integrated into existing devices without adding significant hardware complexity
Solution Approach 2:
The system uses the device's own existing resources (camera, processor, display) to implement posture recognition and control, rather than requiring separate dedicated hardware components. The processing units that already exist in the device are utilized to perform both image display and posture recognition functions

AI summary
A method and apparatus for controlling a virtual object, and a device and a storage medium are provided. The method includes: obtaining posture information of a user in a current frame; in response to determining that the posture information matches a preset posture, controlling movement of a first virtual object and a second virtual object in a current virtual scene based on the posture information; during the movement, in response to determining that the first virtual object and the second virtual object meet a set contact condition, generating a first result; and in response to determining that the first virtual object and the second virtual object do not meet the set contact condition, generating a second result.
