Solution Overview
Problem
There is a need for a system that allows users to easily and quickly access various applications on a locked mobile terminal without unintentionally unlocking the screen, particularly for visually impaired users who cannot clearly view the screen.
Innovation Solution
A method and device that provide a menu interface on the lock screen, allowing users to access specific functions by receiving inputs such as drag and double tap actions, which can unlock the screen and execute corresponding applications or functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock screen is displayed to prevent unauthorized access, then security is improved, but user accessibility to applications is worsened
Solution Approach 1:
The menu interface is segmented into multiple hierarchical levels (first level menu items, second level menu items, etc.). Users can access frequently used applications through the first level without unlocking the screen, while deeper levels provide additional functionality. This segmentation allows security to be maintained while improving accessibility to commonly used applications.
2Ease of operation
If the lock screen is made simple to prevent accidental unlocking, then ease of operation is improved, but functionality is worsened
Solution Approach 1:
The menu interface utilizes a hierarchical dimensional structure with multiple levels of menu items. The first level provides quick access to basic functions, while subsequent levels provide access to more complex functionalities. This dimensional expansion allows the lock screen to maintain simplicity for basic operations while providing comprehensive functionality when needed.
3Adaptability or versatility
If multiple menu levels are provided to increase functionality, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
The menu structure is pre-configured with first level menu items that provide access to commonly used applications and functions. This preliminary organization allows users to access frequently used features without navigating through multiple levels, reducing the perceived complexity while maintaining comprehensive functionality for less common operations.

AI summary
A method, performed by a device, of providing a menu interface on a lock screen of the device, includes receiving a touch input on the lock screen; displaying, on the lock screen, a first level of the menu interface, the first level comprising a first plurality of menu items; receiving a first drag input in a direction of a first menu item from among the first plurality of menu items; and displaying, on the lock screen, a second level of the menu interface, the second level comprising a second plurality of menu items based on the direction of the first drag input.
