Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing methods for controlling virtual objects in virtual scenes require users to perform complex finger operations on multiple virtual keys, leading to reduced efficiency and increased obstruction of the human-computer interaction interface, making it difficult to control both the object's posture and lens direction simultaneously.

Innovation Solution

The method involves using rotation operations around different reference axes to control the posture of virtual objects and the lens in a virtual scene, eliminating the need for traditional key operations and reducing the number of virtual keys displayed, allowing for more intuitive and efficient control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple virtual interaction keys are set on the human-computer interaction interface to control virtual object posture and lens direction, then the control functionality is complete, but the interface is obstructed and operation efficiency decreases

Engineering Contradiction:

Improveoperation efficiencyVSAvoidnumber of virtual keys

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the control functionality from traditional virtual keys and relocates it to the side button of the terminal device. This removes the obstructive virtual keys from the interaction interface while preserving the posture control and lens direction adjustment functions, thereby improving interface clarity and operation efficiency

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The side button is designed to perform multiple functions: controlling virtual object posture (tilting left/right) and adjusting lens direction. By making the side button multi-functional, the patent eliminates the need for multiple separate virtual keys, reducing interface complexity while maintaining complete control functionality

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If traditional virtual key operations are used to control virtual object posture, then the control method is simple to implement, but the user needs to perform multi-finger pressing operations which reduces efficiency

Engineering Contradiction:

Improvecontrol efficiencyVSAvoidoperation complexity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical touch screen key pressing system with a physical side button rotation mechanism. The rotation operation of the side button naturally maps to the tilting directions (left/right) of the virtual object, providing an intuitive and efficient control method that eliminates the need for complex multi-finger pressing operations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

This application provides a method of controlling an object in a virtual scene performed by a terminal device. The method includes: displaying a virtual scene in a human-computer interaction interface; controlling a posture of a virtual object in the virtual scene to tilt in response to a first rotation operation of the terminal device around a first reference axis perpendicular to the interaction interface; controlling a lens of the virtual scene to rotate around a second rotation reference axis parallel to a width direction of the interaction interface in response to a second rotation operation of the terminal device around the second rotation reference axis; and controlling the lens of the virtual scene to rotate around a third rotation reference axis parallel to a length direction of the interaction interface in response to a third rotation operation of the terminal device around the third rotation reference axis.
