Floating Navigation Bar for Foldable Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing system navigation bar in terminal devices occupies valuable screen space and is difficult to control with one hand, especially on larger screens, limiting the usability of navigation functions.
Innovation Solution
A method that employs a foldable display screen to switch between a fixed system navigation bar and a floating system navigation bar, where the fixed bar is stationary and the floating bar can be dragged by the user, allowing for easier one-handed operation by changing its position and form based on the device's orientation and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed system navigation bar is used to occupy the entire bottom line of the screen, then the navigation functions are stable and accessible, but the screen space is greatly wasted and one-handed operation becomes difficult
Solution Approach 1:
The navigation bar is transformed from a fixed bottom-line occupation to a dynamic floating capsule that can be freely positioned and resized on the screen, allowing it to adapt to different screen spaces and user operation needs while maintaining navigation functionality
Solution Approach 2:
The navigation bar changes from a horizontal linear arrangement occupying the entire bottom width to a compact capsule shape that can be positioned anywhere on the screen, effectively utilizing vertical space and reducing horizontal space occupation
2Ease of operation
If a fixed system navigation bar is used at the bottom of the screen, then the navigation controls are always visible, but one-handed operation becomes difficult on large screens
Solution Approach 1:
The navigation bar becomes a draggable floating capsule that can be dynamically repositioned to the bottom corner or other convenient locations for one-handed operation, rather than being fixed at the bottom center
Solution Approach 2:
The navigation bar concentrates all navigation controls within a compact capsule located in the bottom corner area, making all controls accessible within the thumb's natural reach zone for one-handed operation
3Ease of operation
If a fixed system navigation bar occupies the entire bottom line, then navigation controls are easily accessible, but the area cannot be used to display another interface
Solution Approach 1:
The navigation bar transitions from occupying the entire bottom horizontal line to a compact capsule that can be positioned in the bottom corner, freeing up the bottom line area for interface display while maintaining navigation accessibility
Solution Approach 2:
The navigation bar is segmented into a compact capsule containing all essential navigation controls, separating the navigation function from the interface display area and allowing both to coexist without conflict

AI summary
This application discloses a system navigation bar display method, a system navigation bar control method, a graphical user interface, and an electronic device. The method may include: when a foldable display screen of an electronic device changes from a folded state to an expanded state, changing a fixed system navigation bar on an interface displayed on the foldable display screen to a floating system navigation bar, where the floating system navigation bar can be dragged by a user to change a position of the floating system navigation bar relative to another interface element on the interface. When operating the electronic device with one hand, the user can drag the floating system navigation bar to an area in which an operation is conveniently performed with one hand, so that various functions of the system navigation bar can be conveniently used.
