3D Ability Aiming Indicator Aligns Drag Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ability aiming method in multiplayer online battle arena (MOBA) games has poor accuracy and low human-computer interaction efficiency due to deviations between the drag direction on the UI and the ability aiming direction in the three-dimensional virtual environment.
Innovation Solution
The method involves displaying a three-dimensional ability aiming indicator in the virtual environment, with its direction parallel to the drag direction, allowing users to align their hand actions more accurately and reducing unnecessary corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wheel control is used for ability aiming in MOBA games, then the control interface is simple and easy to implement, but the aiming accuracy is poor and human-computer interaction efficiency is low
Solution Approach 1:
The patent introduces a third-dimensional spatial reference system by mapping the two-dimensional wheel control operations onto a three-dimensional coordinate system. The conversion module transforms the drag direction in the two-dimensional UI into a three-dimensional aiming direction that accounts for character orientation, terrain, and spatial relationships, thereby resolving the accuracy limitation of flat wheel controls
Solution Approach 2:
The patent introduces a conversion module as an intermediary between the wheel control input and the ability casting output. This module acts as a mediator that translates and transforms the simplified wheel control signals into accurate three-dimensional aiming directions, bridging the gap between easy-to-use control and precise aiming
2Device complexity
If the drag direction on UI does not align with the ability aiming direction in three-dimensional environment, then the control implementation is straightforward, but unnecessary correction operations are required reducing interaction efficiency
Solution Approach 1:
The patent performs preliminary alignment by pre-calculating and pre-adjusting the aiming direction to match the drag direction before the user completes the aiming action. The conversion module proactively transforms the drag direction into the corresponding three-dimensional aiming direction, so that when the user releases the control, the ability is already cast in the correct direction without requiring additional correction operations

AI summary
This application discloses an ability aiming method in a three-dimensional virtual environment performed at a computer device. The method includes: displaying a user interface (UI) of an application program, the UI including a virtual environment picture obtained by observing the three-dimensional virtual environment from the perspective of a third-person point of view; receiving a drag operation on an ability aiming control in the UI, the drag operation from a first operating point and a second operating point that are located on the ability aiming control, the first operating point being an initial operating point and the second operating point being a current operating point of the drag operation; and displaying a three-dimensional ability aiming indicator in the virtual environment picture in response to the drag operation, an ability aiming direction of the three-dimensional ability aiming indicator being parallel to a drag direction of the drag operation in the UI.
