Flexible Display UI Layout for Grip-Based Control Reachability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with large screens face challenges in user accessibility due to limited reachability of control objects, particularly when folded or unfolded, leading to difficulties in selecting or touching control objects in inaccessible regions.
Innovation Solution
An electronic device and method that detect a user's gripping state and provide duplicate control objects in an optimization region, minimizing finger movement by duplicating control objects to more accessible areas based on the gripping state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased to provide expanded screen, then the screen area is improved, but the user accessibility to control objects deteriorates
Solution Approach 1:
The control objects are segmented and distributed across multiple display regions. When the display is unfolded, control objects are placed in both the first display region and the second display region, allowing users to access controls from either end of the extended screen, thereby maintaining accessibility despite the large overall screen area.
Solution Approach 2:
The patent utilizes the spatial dimension created by the foldable display structure. By placing control objects in different regions that become accessible through different folding states (folded vs. unfolded), the system leverages the third dimension of space to provide multiple access paths to control objects, resolving the accessibility issue on large screens.
2Volume of moving object
If the display is folded to portability, then the device compactness is improved, but the control object accessibility deteriorates
Solution Approach 1:
The system performs preliminary detection of the display's folding state and proactively adjusts the placement or visibility of control objects accordingly. When the display is detected to be in a folded state, control objects are prioritized in the first display region that remains accessible, ensuring user interaction is not disrupted by the compact form factor.
Solution Approach 2:
Different regions of the display are assigned different qualities or priorities based on accessibility. In the folded state, the first display region maintains higher accessibility quality for control objects, while the second display region may have reduced accessibility or different control object placement, optimizing the user experience for the compact configuration.
3Area of stationary object
If the display is unfolded to provide large screen, then the screen area is improved, but the control object reachability deteriorates
Solution Approach 1:
The control objects are segmented and distributed across multiple display regions. When the display is unfolded, control objects are placed in both the first display region and the second display region, allowing users to access controls from either end of the extended screen, thereby maintaining accessibility despite the large overall screen area.
Solution Approach 2:
The system dynamically adjusts control object placement or visibility based on the real-time folding state of the display. As the user interacts with the display in different configurations (folded, partially unfolded, fully unfolded), the system adapts the control object arrangement to maintain optimal accessibility, transforming a static interface into a dynamic one that responds to physical state changes.

AI summary
An electronic device having a flexible display and a method for providing a control object, based on a user's gripping state of an electronic device are provided. The electronic device includes a display, a memory, and a processor. The processor may control the display such that an execution screen of an application is displayed in a designated state of the electronic device. The processor may detect a control object from the execution screen. The processor may determine a user's gripping state. The processor may identify at least one target control object from the control object, based on the designated state and the gripping state. The processor may provide a duplicate control object corresponding to a control object identified as the target control object to an optimization region corresponding to the gripping state.
