Display Control Apparatus Maintaining Visibility During Drag Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face reduced visibility of display items during drag operations on touch panels due to changing slant angles, which can make it difficult to find items, especially when slanting is limited to specific conditions or occurs at short intervals.
Innovation Solution
A display control apparatus with a detection unit, display control unit, and control unit that maintains visibility by stopping scroll effects and maintaining display angles during drag operations, ensuring that display items remain visible and aligned with the user's input, preventing reduction in visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display items are slanted to add depth in the scroll direction, then the display effect is enhanced, but the visibility of display items is reduced
Solution Approach 1:
The display item's slant angle is dynamically adjusted based on the scroll state. During inertial scroll, the slant angle is set to a first value to enhance depth perception. During drag operation, the slant angle is set to a second value (smaller than the first) to maintain visibility. This dynamic adjustment resolves the contradiction by adapting the display effect to different operational contexts.
2Loss of information
If the display item is slanted only under limited conditions to maintain visibility, then visibility is preserved, but the display effect is reduced when continuously scrolling
Solution Approach 1:
The system continuously monitors the user's input state (drag operation vs. continuous scroll) and adjusts the slant angle accordingly. When a drag operation is detected, the slant angle is reduced to maintain visibility. When continuous scrolling is detected, the slant angle is increased to enhance the display effect. This feedback mechanism ensures both visibility and display effect are optimized for the current operational context.
3Adaptability or versatility
If display items are slanted and back again at short intervals during continuous flicking, then the display effect is maintained, but visibility is reduced
Solution Approach 1:
The slant angle is dynamically controlled based on the detected input state. During inertial scroll from continuous flicking, the slant angle is maintained at a larger first value to enhance display effect. When a drag operation is detected, the slant angle is switched to a smaller second value to ensure visibility. This dynamic control prevents the visibility reduction that occurs with frequent slanting while maintaining the display effect during appropriate scroll operations.

AI summary
There is provided a display control apparatus capable of maintaining visibility regarding a display item during a drag operation. The display control apparatus includes a detection unit configured to detect a position input on a screen displayed on a display unit, a display control unit configured to display the display item on the display unit and to perform control to scroll of the display item with a display effect according to a scroll instruction, and a control unit configured to, if the detection unit detects the position input on the screen during the scroll, perform control to stop the scroll with the display effect displayed when the position input has been detected.
