Touchscreen Display Item Selection with Dynamic Interval Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display apparatuses with touch panels face issues with erroneous selections due to small image sizes, leading to cumbersome operations when trying to select the correct image, especially when images are two-dimensionally arrayed, as they often shift to increased image interval modes unnecessarily, complicating user interface interactions.
Innovation Solution
A display control apparatus and method that arranges multiple images on a touch panel screen, allowing users to select an image by designating a touch area, with a second selection unit that chooses a closer image if the initial selection is incorrect, and defines insensitive areas to prevent unintended selections, enabling easy and accurate image selection by restricting row or column shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a larger number of images are displayed at a time to improve overview, then the display ability and visibility are improved, but the possibility of erroneous touch operations increases due to smaller image sizes
Solution Approach 1:
The patent changes the parameter of image interval dynamically. When multiple images are displayed in a grid arrangement, the system detects touch operations and adjusts the interval between images in the touched row or column, effectively changing the spatial parameters to prevent erroneous selections while maintaining dense display
2Reliability
If the image interval is increased to prevent erroneous touch operations, then the accuracy of selection is improved, but the operational procedures become more cumbersome and the user interface becomes less efficient
Solution Approach 1:
The patent applies local quality by increasing the image interval only in the specific row or column where a touch operation occurs, rather than increasing intervals globally. This localized adjustment prevents erroneous selections in the affected direction while maintaining efficient access to images in other directions, thus preserving ease of operation
3Productivity
If images are arranged in a dense two-dimensional array to improve display efficiency, then the productivity of image browsing is improved, but the difficulty of detecting and measuring the correct image increases due to adjacent images being too close
Solution Approach 1:
The patent introduces dynamics by making the image interval adjustable and responsive to user interactions. The system dynamically modifies the display layout based on touch operations, changing the interval between images in the direction of the touch to provide adequate separation for accurate selection while maintaining dense arrangement in other directions

AI summary
This invention relates to a display control apparatus and method capable of appropriately, easily selecting a display item the user wants on a display of a plurality of display items. In one embodiment of the invention, a plurality of display items are arranged on a display screen to cause the display screen having a touch panel to display the plurality of display items as selectable candidates. A first display item is selected among the plurality of display items displayed on the display screen. In a case where the first display item is selected and a touch area in the touch panel is designated by a user, a second display item which is closer to the first display item than the touch area in the display screen is selected.
