Cursor Movement Between Displays Using Motion Vectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mouse cursor movement technologies are limited in moving the cursor between non-adjacent displays, especially when larger and smaller displays are mixed, as they require physical edge matching, which is unsatisfactory and often impossible when displays are not next to each other.
Innovation Solution
A system that identifies a motion vector of a cursor on one display and moves it to another display based on that vector, even if the displays are not physically adjacent, by assuming coplanarity, using angular and distance calculations, and wireless signals to determine the second display's location relative to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If edge matching using pixel boundaries is used for cursor movement, then cursor movement between adjacent displays is enabled, but cursor movement between non-adjacent displays becomes impossible
Solution Approach 1:
The patent creates a virtual copy of the display arrangement in software, where the logical position of displays can differ from their physical positions. The system copies the spatial relationships into a virtual coordinate system that allows flexible cursor routing without requiring physical adjacency or edge matching.
Solution Approach 2:
The patent introduces a virtual display surface or intermediate coordinate system that mediates between the physical display positions and the cursor movement logic. This intermediary layer allows the cursor to move between non-adjacent displays by routing through virtual space rather than requiring direct physical edges.
2Ease of operation
If displays are arranged non-adjacently for better ergonomics or space utilization, then user comfort improves, but traditional cursor movement methods fail
Solution Approach 1:
The patent extends the cursor movement problem from 2D pixel boundary matching into 3D virtual space, adding depth and routing dimensions. By introducing additional spatial dimensions in the virtual coordinate system, the system can route cursors between non-adjacent displays through intermediate virtual positions that don't require physical proximity.
3Productivity
If mixed display sizes are used to optimize workspace, then productivity increases, but adjacent display arrangement becomes difficult or impossible
Solution Approach 1:
The patent changes the parameters used for display positioning from physical pixel coordinates to virtual logical coordinates. By transforming the coordinate system and allowing independent scaling for different display sizes, the system can accommodate mixed display sizes without requiring them to be physically adjacent, as the virtual positions are decoupled from physical dimensions.

AI summary
In one aspect, a device includes at least one processor and storage accessible to the at least one processor. The storage includes instructions executable by the at least one processor to identify a motion vector of a cursor presented on a first display and, based on identification of the motion vector, present the cursor on a second display located in a direction indicated by the motion vector.
