One-Handed Screen Interface Switching via Press-Detected Icon Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in performing one-handed operations on large-screen communication terminals due to the inconvenient placement of 'back key' or 'home key' at the lower portion of the screen, requiring two hands to switch interfaces effectively.
Innovation Solution
A method and apparatus that detect a user's finger pressing period on the screen to initiate an interface switching mode, generating a set of application icons within reach for selection, and expanding these icons upon prolonged pressing, allowing one-step navigation to corresponding application interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen size is increased to meet visual requirements, then the display quality is improved, but the ease of one-handed operation deteriorates due to the distant placement of navigation keys
Solution Approach 1:
The patent segments the navigation functionality by separating the application icon selection from the traditional navigation bar. It creates a dedicated quick switching interface that divides the screen into operational zones, with frequently used applications arranged in easily accessible areas for one-handed operation.
Solution Approach 2:
The patent transitions from the traditional horizontal navigation bar at the bottom to a vertical or radial arrangement of application icons that extends into the vertical dimension of the screen. This dimensional change allows navigation elements to be positioned within the user's one-handed reach zone while maintaining access to multiple applications.
2Productivity
If the traditional navigation bar is used for interface switching, then the system structure is simple, but the operation efficiency deteriorates as users must navigate through multiple steps to switch applications
Solution Approach 1:
The patent implements preliminary action by pre-arranging frequently used application icons in the quick switching interface before the user needs to switch applications. The system anticipates the user's need to switch applications and provides direct access to commonly used functions, eliminating the need to navigate through multiple menu levels.
Solution Approach 2:
The patent enables users to skip the traditional multi-step navigation process by providing direct one-click access to application interfaces. The quick switching interface allows users to bypass the home screen and intermediate menus, rushing directly from the current application to the target application in a single operation.
3Ease of operation
If the screen is zoomed to create a one-handed control area, then the accessibility of the screen is improved, but the functionality is reduced as the back key and home key remain inaccessible
Solution Approach 1:
The patent applies universality by making the quick switching interface serve multiple functions: it acts as both an application launcher and a navigation control center. The interface integrates various navigation functions (switching applications, returning to home, accessing recent apps) within the one-handed control area, eliminating the need for separate navigation keys.
Solution Approach 2:
The patent introduces the quick switching interface as an intermediary between the user and the system navigation functions. Instead of directly accessing the traditional navigation bar that lies outside the one-handed zone, users interact with this intermediary interface that translates their selections into system navigation commands, bridging the gap between limited reach and full functionality.

AI summary
Provided are a method and apparatus for switching screen interface and Terminal. The method for switching screen interface includes: detecting a first actual pressing period of pressing any point in a screen operation area by a user's finger; when the first actual pressing period is greater than or equal to a first preset pressing period, starting an interface switching mode at a current interface, that is, generating a set of application icons in the screen operation area where the user's finger can touch for the user to select; and based on the application icon sets, enabling the current interface to skip to a corresponding application interface in one step by clicking an application icon needing to be selected. The method has the beneficial effects of convenient use, large application range and good user experience.
