Touch Operation Control for Simultaneous Virtual Object and Perspective Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing virtual environment display systems, users face difficulties in seamlessly controlling virtual objects and adjusting perspectives due to the need to release the finger after clicking operation controls before swiping, which hinders efficient interaction.
Innovation Solution
A method and apparatus that allow virtual object control and perspective adjustment through a single touch operation, where the touch position can move from within to outside the response region of a function control, enabling continuous swiping to perform actions and change perspectives without releasing the finger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user clicks the operation control to control the virtual object, then the virtual object can perform the corresponding behavior, but the user must release the finger to trigger the swiping operation, making the operation complex
Solution Approach 1:
The patent combines the function control operation and the perspective adjustment operation into a single touch operation. When the user touches and moves their finger from the function control area to the virtual environment picture area, the system simultaneously detects both the function selection (through the initial touch on the function control) and the perspective adjustment (through the movement to the picture area), eliminating the need to release the finger between operations.
Solution Approach 2:
The single touch operation serves multiple functions: it controls the virtual object to perform a behavior through the function control area and simultaneously adjusts the perspective through the virtual environment picture area. This multi-functional design allows one touch operation to replace what would traditionally require two separate operations (clicking the function control, releasing, then swiping for perspective adjustment).
2Productivity
If the user releases the finger after clicking the operation control, then the swiping operation can be triggered, but the adjustment efficiency of the virtual environment picture decreases
Solution Approach 1:
The patent enables continuous detection of touch operations without requiring finger release. The system continuously monitors the touch state from the function control area through the virtual environment picture area, allowing the user to maintain continuous contact while performing both function selection and perspective adjustment. This continuous action eliminates the interruption caused by finger release and improves adjustment efficiency.
3Reliability
If the click operation and swiping operation are independent, then each operation can be processed separately, but the user interface becomes less responsive to continuous input
Solution Approach 1:
The patent implements a dynamic operation detection mechanism that adapts to the user's continuous touch input. Instead of treating click and swipe as separate discrete operations, the system dynamically interprets the touch trajectory: initial contact in the function control area triggers function selection, while movement to the picture area triggers perspective adjustment. This dynamic interpretation maintains reliable operation detection while enabling smooth, continuous user interaction.

AI summary
A display method includes displaying a first virtual environment picture, the first virtual environment picture being a picture for observing a virtual environment including a virtual object from a first perspective, and controlling the virtual object to perform a first function in response to a first touch operation on a first function control. At least a part of the first touch operation is located in a response region of the first function control. The method further includes changing a displayed perspective of the virtual environment in response to moving a touch position of the first touch operation from a first position to a second position. At least one of the first position or the second position is located outside the response region of the first function control, and the displayed perspective of the virtual environment is changed based on the moved touch position of the first touch operation.
