Cross-Screen Cursor Navigation Across Resolution Boundaries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple display screens are used, the cursor often cannot be moved from one screen to another due to differences in resolution or alignment, causing navigation issues between adjacent screens.
Innovation Solution
A processing method and device that allow an identification object, such as a cursor or mouse, to be moved across display areas with different resolutions by outputting partial images on each screen and using movement instructions to align and relocate the object across edges, ensuring seamless cross-screen movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display screens with different resolutions are used, then display versatility and coverage area are improved, but cursor movement reliability and navigation smoothness deteriorate
Solution Approach 1:
The patent changes the coordinate system parameters and resolution parameters when the cursor approaches different screen edges. The system dynamically adjusts the mapping relationship between physical screen coordinates and logical coordinates based on the resolution of the target screen, enabling smooth cursor transition across screens with different resolutions
Solution Approach 2:
The patent introduces an edge identification object as an intermediary element that mediates between screens of different resolutions. This object is displayed at the edge of the current screen and helps the user understand the cursor's position relative to the next screen, facilitating reliable cross-screen navigation despite resolution differences
2Area of stationary object
If multiple display screens with different resolutions are used, then display area coverage is improved, but navigation smoothness and user experience deteriorate
Solution Approach 1:
The system dynamically changes display parameters including the size and position of the edge identification object based on the resolution differences between screens. When transitioning to a lower resolution screen, the edge identification object is adjusted to maintain appropriate visual prominence, ensuring smooth navigation experience across screens of varying resolutions
Solution Approach 2:
The patent applies different display qualities and characteristics to different regions of the multi-screen system. The edge identification object has enhanced visual properties (different color, size, or position) compared to regular cursor elements, making it locally optimized for facilitating cross-screen navigation at screen boundaries
3Measurement precision
If cursor position is precisely tracked across screens, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system automatically detects when the cursor approaches a screen edge and autonomously displays the appropriate edge identification object without requiring user intervention. The system self-adjusts the coordinate mapping and visual indicators based on real-time cursor position and screen configuration, maintaining precision while managing complexity through automation

AI summary
The present disclosure provides a processing method. The method includes outputting first content in a first display area of a first display device, the first content including an identification object, the edge of the first area being an edge area between the first display area and a second display area of a second display device; receiving a movement instruction for moving the identification object from the first display area to the second display area; and moving the identification object from a first position in the first display area to a second position in the second display area in response to the movement instruction, the first position being a position on the edge of the first area.
