Touch Display Item Rearrangement via Distance Threshold Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control apparatuses make it cumbersome for users to rearrange display items while maintaining the order of other items, especially when moving a display item to a new position requires navigating through other items.
Innovation Solution
A display control apparatus with a touch detection unit and a control unit that performs first and second rearrangement controls based on the distance and direction of a touch operation, allowing users to easily move and rearrange display items by dragging them within a predetermined distance in one direction or swapping them with other items when the touch operation exceeds a certain distance in a different direction.

Engineering Contradiction Analysis
1Ease of operation
If a user moves a display item to a new position by touch operation, then the display item can be rearranged, but the order of other display items changes unintentionally
Solution Approach 1:
The patent segments the rearrangement operation into two independent modes: first rearrangement control for maintaining order and second rearrangement control for simple swapping. This segmentation allows the system to preserve the original order of display items while still enabling flexible rearrangement through distinct operational modes triggered by different touch operation characteristics.
Solution Approach 2:
The patent changes the parameter of touch operation distance threshold to differentiate between two rearrangement modes. When the touch operation distance is less than the threshold, first rearrangement control is activated to maintain order; when the distance exceeds the threshold, second rearrangement control is activated for simple swapping. This parameter change enables the system to handle different user intentions without changing the underlying hardware structure.
2Ease of operation
If a user performs touch operation to move a display item, then the display item can be repositioned, but the operation becomes cumbersome when maintaining order of other items
Solution Approach 1:
The patent implements self-service by having the system automatically determine which rearrangement control to execute based on the touch operation characteristics. The control unit automatically compares the touch operation distance with the predetermined threshold and selects the appropriate rearrangement mode without requiring additional user input or complex manual manipulation, thus simplifying the operation while maintaining order.
Solution Approach 2:
The patent introduces dynamics by making the rearrangement control adaptive to the touch operation characteristics. The system dynamically switches between first and second rearrangement controls based on the distance threshold, allowing the control mechanism to adjust its behavior according to the user's intended action rather than following a fixed rigid procedure.
3Ease of operation
If a user wants to simply swap two display items, then the operation should be straightforward, but the system cannot distinguish between simple swapping and ordered rearrangement
Solution Approach 1:
The patent uses parameter changes by setting a predetermined distance threshold that serves as the differentiation criterion between simple swapping and ordered rearrangement modes. This parameter allows the system to adapt to different user intentions: short-distance touch operations trigger ordered rearrangement control, while long-distance operations trigger simple swapping control, thus providing versatility without complicating the user interface.

AI summary
A touched display item from among a plurality of display items is dragged by a touch operation, and in a case where an amount of movement of the touch operation is less than a predetermined distance in a second direction, a plurality of items located between an original position of the touched display item and a current position of the touched display item are moved, and in a case where the amount of movement of the touch operation is greater than or equal to the predetermined distance in the second direction, in a case where the touch operation ends, the touched display item is inserted where the touch operation ended and a display item located at the position where the touched display item is inserted is moved to the original position of the touched display item.
