Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual object control methods in computer technologies cannot realistically simulate actions as they are limited to fixed directional movements and do not allow for acceleration or deceleration, failing to accurately mimic real-life scenarios.
Innovation Solution
A method and apparatus that determine the viewing angle and acceleration of a virtual object based on touch operations in a control region, incorporating gravitational acceleration to enable dynamic movement and orientation changes, allowing the virtual object to move in any direction and simulate realistic actions such as falling, diving, walking, or swimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual joystick region is used to control virtual object movement, then the control operation is simple, but the movement direction is limited to fixed directions (up, down, left, right) and cannot simulate realistic actions
Solution Approach 1:
The patent transforms the static fixed-direction control into dynamic continuous control by introducing a virtual mouse region that responds to touch operations with variable direction and magnitude. The virtual object's movement direction and speed are dynamically adjusted based on the touch operation's position and intensity, enabling realistic simulation of human actions while maintaining ease of operation through intuitive touch interface.
2Device complexity
If the virtual object moves at constant speed in fixed directions, then the control mechanism is simple, but the virtual object cannot accelerate or decelerate, reducing realism
Solution Approach 1:
The patent changes the motion parameters from constant speed and fixed direction to variable speed and dynamic direction. By calculating acceleration based on the difference between current and previous positions, and using touch operation intensity to modulate speed, the system enables the virtual object to accelerate and decelerate naturally, significantly improving the realism of simulated actions while keeping the control mechanism relatively simple.
3Ease of manufacture
If the viewing angle is fixed, then the display is simple, but the virtual object cannot change orientation or move toward any direction, limiting simulation capability
Solution Approach 1:
The patent implements dynamic viewing angle adjustment where the camera automatically follows and orients toward the virtual object's movement direction. The viewing angle changes dynamically based on the virtual object's position and acceleration vector, allowing the user to observe the virtual object from optimal perspectives during complex movements, enhancing simulation realism without requiring complex manual camera control mechanisms.

AI summary
The present disclosure provides method and apparatus, an electronic apparatus, and a storage medium for a virtual object control, and relates to the field of computer technologies. In the present disclosure, when a touch operation in a control region is detected, a viewing angle of a virtual scene is determined; an acceleration of a virtual object during a falling process is obtained with reference to the touch operation, the viewing angle, and the gravitational acceleration; and the virtual object is controlled to fall according to the acceleration. In this way, an action of a character can be realistically simulated by determining non-fixed moving directions and speeds.
