Adjustable Cursor Direction Prompting for Edge Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch-sensitive cursors face difficulties in accurately interacting with objects near the edge of a high-resolution touch panel due to fixed directional constraints, limiting user control and convenience.
Innovation Solution
A method and system for detecting the cursor's location on a display and providing directional adjustment prompts to allow the cursor to change direction based on its position, enabling users to interact with objects more effectively by displaying adjustable direction information when the cursor's set direction differs from the indicated direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cursor tip maintains a fixed direction to simplify the cursor structure, then the device complexity is reduced, but the ease of operation deteriorates when the cursor is near the display edge
Solution Approach 1:
The cursor tip direction is changed from fixed to adjustable based on cursor position. When the cursor is detected to be within a certain distance from the display edge, the system dynamically adjusts the cursor tip direction to point toward the center of the display, enabling continued smooth operation near edges while maintaining relatively simple cursor structure.
2Measurement precision
If the cursor touch and pressure part area is increased to improve touch accuracy, then the measurement precision is improved, but the area occupied by the cursor increases
Solution Approach 1:
The cursor design concentrates the touch and pressure function in a localized area (the touch and pressure part) while allowing the cursor tip direction to be adjusted independently. This enables accurate touch operation with a compact cursor structure that doesn't require a large overall area.

AI summary
A prompting method of an adjustable direction of a cursor for a portable electronic apparatus includes the follow steps: detecting a location of a cursor in a display, with the cursor indicating an indicated direction; determining whether any set direction corresponding to the location of the cursor is different from the indicated direction; and if any set direction corresponding to the location of the cursor is different from the indicated direction, displaying a directional adjustment prompting information for prompting at least one adjustable direction of the cursor corresponding to the location of the cursor.
