Virtual Item Control via Radial Interface for Mobile Gaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual object control systems in shooting games require a large display region for virtual items, leading to an excessive screen occupation and reduced user interface conciseness.
Innovation Solution
A method and apparatus for controlling virtual objects in a user interface, where a first control switches the use state of a virtual item and a second control switches between virtual items, reducing the screen occupation by displaying only the currently used item and allowing efficient item switching through integrated controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual items are displayed horizontally at the bottom center of the match interface, then users can easily access and switch between virtual items, but the display region occupies too large a proportion of the screen
Solution Approach 1:
The patent segments the virtual item display from the traditional horizontal arrangement at the bottom center, instead integrating it into a circular control structure located at the lower left corner. This segmentation allows the virtual item display to be part of a compact control cluster rather than a separate large display region, reducing overall screen occupation while maintaining accessibility.
Solution Approach 2:
The patent merges the virtual item switching function with the circular control structure that also contains movement controls. By combining multiple control functions (movement directions and virtual item selection) into a single integrated circular interface, the design reduces the total area required compared to having separate display regions for each function.
2Ease of operation
If multiple virtual items are displayed horizontally, then item selection is straightforward, but the display requires a large display region
Solution Approach 1:
The patent transitions from a horizontal linear arrangement of virtual items to a circular radial arrangement. Instead of displaying items side-by-side in one dimension, the items are arranged along the circumference of a circle, allowing selection through angular positioning. This dimensional change enables compact presentation of multiple items without requiring extensive horizontal space.
Solution Approach 2:
The circular control structure dynamically adapts to show different virtual items based on rotation or selection input, rather than requiring all items to be simultaneously visible in a static horizontal layout. This dynamic approach allows multiple items to be accessible through sequential selection within a compact circular area.

AI summary
A virtual object control method includes displaying a user interface including a first virtual item and an item switching control, switching the first virtual item in the user interface to a second virtual item next in line after the first virtual item in an item list in response to a first operation on the item switching control, controlling a virtual object to handhold the second virtual item, switching the second virtual item in the user interface to a third virtual item selected from the item list in response to a second operation on the item switching control, and controlling the virtual object to handhold the third virtual item.
