Virtual Prop Pickup Using View-Direction Target Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often make mistouches when controlling game characters to pick up virtual props in complex game scenes, leading to low pickup accuracy.
Innovation Solution
The method involves determining candidate virtual props with a virtual interaction object, using the game character's view direction to identify a target prop, and controlling the character to pick up the target prop, assisted by virtual interaction objects like bounding boxes and identifiers to enhance precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user controls the game character to pick up virtual props by clicking in a complex game scene, then the pickup operation can be performed, but the accuracy of picking up the correct prop decreases due to mistouch
Solution Approach 1:
The patent introduces a detection ray as an intermediary tool between the user's click operation and the virtual prop selection. The detection ray visually indicates the target prop and provides a confirmation mechanism, reducing mistouch errors in complex game scenes while maintaining ease of operation through the familiar click interface
Solution Approach 2:
The patent replaces the direct mechanical click-to-select mechanism with an optical detection ray mechanism. Instead of directly selecting a prop through click coordinates, the system uses a visual detection ray to indicate the target and requires confirmation, substituting the mechanical direct-selection system with an optical indication system that reduces errors
2Measurement precision
If virtual interaction objects like bounding boxes and identifiers are added to assist prop selection, then the selection precision improves, but the device complexity increases
Solution Approach 1:
The patent extracts and displays only the essential identification features of virtual props (such as bounding boxes and key identifiers) rather than showing all possible information. This selective extraction provides sufficient precision for prop selection while minimizing the added interface complexity by showing only the most critical visual cues
3Measurement precision
If the detection ray is used to indicate the target prop, then the pickup accuracy improves, but the time required for the selection process increases
Solution Approach 1:
The patent performs preliminary actions by automatically generating and displaying the detection ray as soon as the user initiates a selection operation. The detection ray is prepared in advance and continuously updated to reflect the current target, eliminating the need for users to manually search for props and reducing the overall selection time while maintaining high accuracy

AI summary
The present disclosure provides a method for picking up a virtual prop. The method includes: determining at least one candidate virtual prop from among one or more virtual props in a game scene, the candidate virtual prop being configured with a virtual interaction object, where the game scene, the one or more virtual props and a game character are displayed on a graphical user interface of a terminal; in response to a view direction of a game view screen corresponding to the game character pointing toward the virtual interaction object, determining a target virtual prop corresponding to the virtual interaction object from among the at least one candidate virtual prop; and in response to a pickup operation for the target virtual prop, controlling the game character to pick up the target virtual prop.
