Touchscreen Auxiliary Control Region Mapping for MOBA Game Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touchscreen-based control methods for MOBA games on mobile devices are inconvenient due to the need for large drag operations, which can cover intended target areas, reducing operation efficiency.
Innovation Solution
A touchscreen-based control method that displays an auxiliary control region with a smaller area and a candidate effect range region with a larger area, establishing a mapping relationship between their locations, allowing users to adjust the effect range by dragging the icon within the auxiliary control region, thereby performing operations on virtual targets without needing extensive drag movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user performs a drag operation in a large range on the touchscreen to adjust the effect range, then the effect range can be positioned, but the operation becomes inconvenient and may cover the intended target area
Solution Approach 1:
The touchscreen is segmented into two distinct regions: an auxiliary control region for operation and a candidate effect range region for display. This segmentation allows the control region to be smaller and more manageable, improving operation convenience while the mapping relationship ensures precise positioning accuracy is maintained in the larger effect range region.
Solution Approach 2:
A mapping relationship is introduced as an intermediary mechanism between the auxiliary control region and the candidate effect range region. This mapping allows small movements in the control region to be translated into precise positioning in the effect range region, resolving the contradiction between operation convenience and positioning accuracy.
2Ease of operation
If the auxiliary control region has a smaller area, then operation convenience is improved, but the candidate effect range region needs to be larger to maintain the mapping relationship
Solution Approach 1:
The auxiliary control region is nested within or positioned relative to the candidate effect range region through a mapping relationship. This nesting allows the control region to be smaller for convenience while the effect range region maintains its larger area for comprehensive coverage, with the mapping relationship coordinating their sizes.

AI summary
A touchscreen-based control method is disclosed. The method includes: detecting a first touch point acting on a first icon displayed on a touchscreen; displaying an auxiliary control region and a candidate effect range region, an area of the candidate effect range region being greater than an area of the auxiliary control region; obtaining a first effect range according to a location of the first touch point, and a mapping relationship between a location of the candidate effect range region and a location of the auxiliary control region when the first touch point is moved to the auxiliary control region; and performing, on a virtual target in the obtained first effect range, a first operation corresponding to the first icon.
