Offset Cursor Mode for Marine Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marine electronic display devices face challenges in providing unobstructed visibility of cursors during finger-based interactions, as the cursor moves under the finger, obstructing the user's view, which complicates navigation and data selection in marine traffic monitoring.
Innovation Solution
Implementing an offset cursor mode that displays the cursor at a predetermined distance from the finger, allowing it to move independently without obstruction, enabling easier navigation and data selection by freezing panning mode and providing an adjustable offset distance for improved visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the cursor moves under the finger during finger-based interactions, then the cursor follows the user's touch precisely, but the cursor becomes obstructed from view, reducing visibility
Solution Approach 1:
The patent introduces a virtual dimension by displaying a second cursor at an offset position from the first cursor. This creates a visual representation that exists in a different spatial dimension on the display, allowing the user to see the cursor position without the physical finger obstructing the view. The offset cursor provides positional information in a dimension that is visually accessible while the finger interacts in the physical contact dimension.
2Ease of operation
If a standard cursor is used that moves directly under the finger, then the interaction is simple and direct, but the user cannot see the cursor position clearly during movement
Solution Approach 1:
The patent introduces a second cursor as an intermediary visual element that mediates between the user's finger and the display interface. This intermediary cursor provides visual feedback about the interaction position without being physically obstructed by the finger, allowing the user to see the cursor position clearly while maintaining simple finger-based interaction.
3Measurement precision
If the cursor is displayed at the exact touch position, then the precision of data selection is maximized, but the finger obstructs the view of the cursor and surrounding data
Solution Approach 1:
The patent creates a visual dimension separate from the physical interaction dimension by offsetting the second cursor from the first cursor. This allows the user to see the precise data selection position without the finger blocking the view, reducing the time needed to locate and select data while maintaining selection precision.
4Ease of manufacture
If an offset cursor is displayed at a predetermined distance from the finger, then the cursor remains visible during finger movement, but the cursor no longer directly indicates the exact touch position
Solution Approach 1:
The second offset cursor serves as an intermediary visual indicator that provides approximate position information while remaining visible. It mediates between the need for visibility and precise position indication, allowing users to track cursor movement and anticipate the exact touch position without direct obstruction.

AI summary
Described herein are implementations of various technologies for a method and apparatus for providing marine electronic data. In one implementation, a screen may display marine electronic data. A cursor may be provided that is movable by placement of a finger over the cursor. A request to display the cursor at a position such that the cursor is not obstructed from view by the finger may be received. The requested cursor may be displayed at the position on the screen.
