Bendable Display Drag Control for Temporary Touch Lift-Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operating a bendable display can be difficult, especially when the screen is in a bent form, as fingers may unintentionally lift off at bent areas during operations like dragging.
Innovation Solution
An information processing apparatus with a bendable display that includes a touch sensor, memory, and processor to manage window arrangements and icon displays, adjusting operations based on the display's form and angle, ensuring icons remain visible during drag operations even when temporarily interrupted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is bent to provide flexibility and portability, then adaptability is improved, but ease of operation deteriorates due to unintentional finger lift-off at bent areas
Solution Approach 1:
The system dynamically adjusts icon display behavior based on real-time detection of display bending state. When bending is detected, the icon display continuation process is activated to maintain icon visibility during drag operations, whereas in flat state the icons are ended immediately upon drag completion. This dynamic adaptation resolves the contradiction by making the system responsive to the physical state of the display.
Solution Approach 2:
The system changes the display parameter (icon visibility duration) based on the display's physical form. In bent form, icons continue to be displayed for a predetermined time after drag operation completion, while in flat form, icons are ended immediately. This parameter change allows the system to accommodate the operational difficulties introduced by bending without sacrificing the flexibility benefit.
2Device complexity
If the icon is ended immediately upon drag operation completion, then device complexity is reduced, but ease of operation deteriorates when the display is bent and finger lift-off occurs
Solution Approach 1:
The control logic dynamically switches between two modes: immediate icon termination in flat state and continued icon display in bent state. This dynamic approach adds minimal complexity only when needed (bent state detection and conditional continuation), while maintaining simple immediate termination behavior in the more common flat state, thus resolving the contradiction between complexity and operational reliability.
Solution Approach 2:
The system changes the icon display duration parameter based on display bending detection. By extending the display time in bent form, the system compensates for unintentional finger lift-off without requiring complex additional controls, maintaining operational reliability while adding only conditional logic based on the bending state.
3Ease of operation
If the icon display is continued for a predetermined time after drag operation completion, then ease of operation is improved for bent displays, but loss of time increases due to extended icon visibility
Solution Approach 1:
The system changes the icon display duration parameter dynamically: in bent form, icons continue to be displayed for a predetermined time to allow users to complete operations despite finger lift-off; in flat form, icons are ended immediately to minimize display time. This conditional parameter adjustment resolves the contradiction by applying the time extension only when operationally necessary.
Solution Approach 2:
The icon display continuation process is dynamically activated only when bending is detected, creating a time extension that is adaptive to the physical state. This dynamic behavior ensures that time loss is incurred only when it provides operational benefit (bent state), while maintaining efficient immediate termination in flat state, thus balancing ease of operation against time loss.

AI summary
An information processing apparatus includes a bendable display, a touch sensor configured to detect a touch operation on a screen area of the display, and a processor configured to perform control of arranging and displaying a window of a running application on the screen area of the display, and performs: an icon display process of displaying, in response to a drag operation being started on the window displayed on the screen area of the display, an icon for accepting an operation based on an operation position of the drag operation while continuing the drag operation on the screen area of the display, an icon display end process of ending display of the icon when the drag operation is completed on the window, and an icon display continuation process of continuing the display of the icon when the drag operation is completed on the window but is only temporarily interrupted.
