Hold Screen Shortcut Execution via Drag Pattern Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face inconvenience when trying to execute user-intended menus or applications during the hold function, as they require termination of the hold function, resulting in a delay before execution.
Innovation Solution
A method and apparatus that allow immediate execution of user-intended menus or applications by recognizing specific drag patterns, enabling the execution of a shortcut function while the hold function is active, thereby eliminating the need to terminate the hold function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hold function is executed to prevent unintended operations, then operation safety is improved, but execution speed of user-intended menus or applications deteriorates due to required termination delay
Solution Approach 1:
The patent segments the input recognition process by introducing drag pattern recognition as a distinct mechanism that operates independently within the hold function mode. The controller identifies specific drag patterns (e.g., circular motion, figure-eight) to distinguish user-intended shortcuts from accidental inputs, allowing shortcut execution without terminating the hold function. This segmentation resolves the contradiction by maintaining hold function protection while enabling rapid shortcut access.
2Loss of time
If the hold function is terminated to execute user-intended menu or application, then execution speed is improved, but operation safety deteriorates due to potential unintended operations
Solution Approach 1:
The patent introduces drag pattern recognition as an intermediary mechanism between the hold function and shortcut execution. Instead of directly terminating the hold function to execute shortcuts, the system uses drag pattern identification as a mediator that validates user intent. This intermediary allows the hold function to remain active while still enabling shortcut execution, thus improving execution speed without compromising operation safety.
3Ease of operation
If drag pattern recognition is added to enable shortcut execution during hold function, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by enabling the drag pattern recognition mechanism to serve multiple purposes: it identifies user-intended shortcuts, maintains hold function protection, and provides a universal input method that works across different shortcut types. This universal approach improves ease of operation while managing device complexity by consolidating the recognition logic into a single reusable framework rather than separate mechanisms for each shortcut type.

AI summary
An apparatus and method for executing a shortcut function in a portable terminal are provided, in which a display is included, a memory stores at least one drag pattern, a hold screen shortcut list, and a volume control menu, and a controller displays a hold screen by executing a hold function, recognizes a drag pattern received from a user, compares the recognized drag pattern with the stored at least one drag pattern, and executes the hold screen shortcut function for executing the shortcut function during executing the hold function when the recognized drag pattern is identical to a first drag pattern among the stored at least one drag pattern.
