Icon Rearrangement Marker for Precise Drag-and-Drop Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information processing systems, users face difficulties in accurately rearranging icons on a screen due to discrepancies between intended and actual rearrangement positions during drag and drop operations, leading to unintended results.
Innovation Solution
An information processing apparatus with an image display unit, arrangement unit, and marker display unit that displays a marker image between the intended and adjacent images, helping users visually confirm the correct rearrangement position and minimize position differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If images are automatically arranged in descending order at ranked arrangement positions, then the arrangement is systematic and orderly, but the user cannot easily rearrange images to desired positions
Solution Approach 1:
The patent introduces arrangement areas as intermediary zones between images. When a user drops an image, the system determines which arrangement area the drop occurred in and places the image at the corresponding ranked position within that area. This intermediary mechanism bridges the gap between user intent (dropping in a general area) and system action (precise positioning), resolving the contradiction between ease of operation and positioning accuracy.
2Ease of operation
If a user performs drag and drop to move an image to another image's position, then the operation is simple, but the actual rearrangement position may differ from the intended position
Solution Approach 1:
The patent divides the screen into multiple arrangement areas, each associated with a specific ranked arrangement position. Instead of allowing continuous positioning, the system segments the rearrangement space into discrete zones. When a user drops an image, the system identifies which segment (arrangement area) the drop occurred in and places the image at the corresponding position, ensuring accurate and predictable rearrangement while maintaining operational simplicity.
3Stability of the object's composition
If images are arranged in fixed ranked positions, then the layout is stable and organized, but user flexibility in repositioning is limited
Solution Approach 1:
The patent implements a dynamic arrangement system where the ranked positions and arrangement areas are reconfigured based on user interactions. When images are rearranged, the system dynamically updates the arrangement areas and ranked positions to accommodate new configurations. This allows the system to maintain stability through structured ranked positions while providing adaptability through dynamic reconfiguration based on user needs.

AI summary
An information processing apparatus includes an image display unit, an arrangement unit, and a marker display unit. The image display unit displays images. Upon acceptance of an instruction to rearrange an image selected from among the images in an arrangement area including one of the images, the arrangement unit rearranges the selected image at a rearrangement position in the arrangement area on the image display unit. The marker display unit displays a marker image between an image at the rearrangement position and an image arranged lower in rank than the image at the rearrangement position when the rearrangement position is lower than the position of the selected image, or displays the marker image between the image at the rearrangement position and an image arranged higher in rank than the image at the rearrangement position when the rearrangement position is higher than the position of the selected image.
