Dragging Cursor with Variable End Shape for Input Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses do not effectively enhance operability during input operations by dragging, as users struggle to recognize the positions, distance, and direction of the start and end points of dragging.
Innovation Solution
An information processing apparatus with a control unit that displays a cursor elongating from the start to the end point of dragging, with varying size or shape at each end, allowing users to distinguish and recognize the start and end points, thereby improving operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional cursor is displayed during dragging, then the input operation can be executed, but the user cannot recognize the positions, distance, and direction of the start and end points of dragging
Solution Approach 1:
The cursor changes its appearance (size and shape) to provide visual information about the dragging operation. The cursor is displayed larger at the start point and smaller at the end point, creating a gradient effect that helps users recognize the direction and distance of dragging.
Solution Approach 2:
The cursor is segmented into multiple portions along the dragging path, with each portion having different sizes. This segmentation allows the cursor to simultaneously indicate the start point, end point, and intermediate positions, providing comprehensive dragging information.
2Loss of information
If the cursor size and shape are made different at start and end points, then the user can recognize direction and distance, but the device complexity increases
Solution Approach 1:
The cursor is designed as a dynamic element that automatically adjusts its size and shape based on the dragging parameters. The control unit dynamically modifies the cursor appearance in real-time as the user performs the dragging operation, eliminating the need for manual configuration.
Solution Approach 2:
The cursor automatically provides the necessary information about the dragging operation without requiring additional user input or system configuration. The cursor self-adjusts its appearance to reflect the current dragging state, making the system self-explanatory.

AI summary
An information processing apparatus includes: an operation unit; and a control unit performing a process corresponding to dragging and displaying, on a display unit, a cursor which elongates from a start point of the dragging to an end point of the dragging and of which at least one of a size and a shape is different at one end portion, which is on a side of the start point of the dragging, and at the other end portion, which is on a side of the end point of the dragging, when the dragging is executed through the operation unit.
