Icon Display Control with Deletion Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing icon display controlling devices face usability issues due to limited display area, requiring complex operations to delete and replace icons, which restricts the ability to add new icons and is cumbersome, especially in situations where users have limited opportunity to interact with the screen.
Innovation Solution
An icon display controlling device and program that includes an area displaying unit, a deleting mode switching unit, and an icon positioning unit, allowing for the deletion and replacement of icons through simpler drag-and-drop operations by switching to a deleting mode and utilizing a temporary placement area for visible deletion and placement of icons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area size is limited, then the device structure remains compact, but the number of icons that can be displayed on a single screen is limited
Solution Approach 1:
The patent introduces a temporal dimension to icon display by implementing multiple display modes (normal mode and deletion candidate display mode) that switch over time. This allows the limited display area to effectively show more icon information across different time states, resolving the contradiction between limited display area and the need to display numerous icons.
2Ease of operation
If complex operations are required for deleting and replacing icons, then icon placement control is precise, but usability deteriorates
Solution Approach 1:
The patent implements dynamic behavior where the display mode automatically changes based on user interaction. When a user performs a specific operation on an icon, the system dynamically switches from normal display mode to deletion candidate display mode, and then to execution mode. This dynamic adaptation simplifies the user experience while maintaining precise control over icon deletion and replacement operations.
Solution Approach 2:
The system automatically manages the deletion process by displaying deletion candidate information and waiting for user confirmation. This self-service mechanism eliminates the need for users to navigate through multiple manual deletion steps, thereby improving usability while maintaining precise control over the icon replacement process.
3Loss of time
If multiple mode switching operations are required, then deletion control is accurate, but operation time increases
Solution Approach 1:
The patent displays deletion candidate information in advance before the actual deletion occurs. By showing which icons will be deleted and allowing users to review this information beforehand, the system enables users to make informed decisions quickly. This preliminary action reduces the time needed for deletion operations while maintaining accurate control through user confirmation.

AI summary
An icon display controlling device includes an area displaying unit for causing a display to display a first display area within which an icon can be placed; a deleting mode switching unit for switching to a deleting mode that enables deletion of a second icon that has already been placed in the first display area, in response to performance of a predetermined operation for placing a first icon in the first display area; and an icon positioning unit for placing the first icon in the first display area upon deletion of the second icon in the deleting mode.
