Cursor Movement Control for Multi-Region Display Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical imaging settings, displaying multiple screens on a single display device requires labor-intensive cursor movement and can lead to unintended cursor behavior when using multi-monitor connections, affecting user convenience and manipulability.
Innovation Solution
A cursor movement control method that allows for seamless movement between multiple display regions on a single screen by receiving instructions for display or non-display of regions and controlling cursor position based on boundary information, reducing the need for users to manually move the cursor between regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple display regions are simultaneously displayed on one display device, then the need for multiple physical monitors is eliminated, but cursor movement becomes complex and may result in unintended cursor behavior
Solution Approach 1:
The display screen is divided into multiple display regions (first display region and second display region), each corresponding to different screens. The cursor movement control device segments the cursor movement path based on boundary information between these regions, enabling independent control of cursor behavior in each region while maintaining seamless transition.
Solution Approach 2:
The cursor movement control device acts as an intermediary between the mouse input and the display regions. It receives mouse input, determines the target display region based on boundary information, and controls cursor movement accordingly, preventing unintended cursor behavior when transitioning between regions.
2Adaptability or versatility
If display region B is superposed on display region A, then both screens can be viewed simultaneously, but the cursor may disappear or behave unexpectedly when entering the superposed region
Solution Approach 1:
The cursor movement control device performs preliminary action by determining boundary information between display regions in advance and pre-configuring cursor movement paths. When the user moves the mouse, the device immediately determines which region the cursor should enter based on pre-established boundary information, preventing cursor disappearance or unexpected behavior.
Solution Approach 2:
The system implements feedback by continuously monitoring the mouse position and comparing it with boundary information to determine the appropriate display region. This feedback loop ensures the cursor is always visible and behaves predictably, adjusting the cursor position based on real-time input and pre-defined regional boundaries.
3Ease of operation
If manual cursor movement is required to switch between display regions, then cursor control precision is maintained, but user convenience and productivity are reduced
Solution Approach 1:
The cursor movement control device performs self-service by automatically determining the target display region based on boundary information and mouse position. The system autonomously controls cursor movement between regions without requiring manual user intervention, thereby maintaining precision while significantly improving user convenience and productivity.

AI summary
A problem is to provide a cursor movement control method by which labor necessary for a movement of a cursor can be reduced and convenience of a user can be improved even when a plurality of screens is displayed on one display device, a computer program, a cursor movement control device, and an image display system. A technical solution is such that a display image creation unit (13) sets a region in a display image corresponding to a display region A to a region a and a region in the display image corresponding to a display region B to a region b, and allocates the regions a and b into the display image. An input unit (12) receives an instruction for whether or not to superposedly display the display region B on the display region A on the display screen (54). A cursor movement control unit (15) controls the movement of the cursor between the region a and the region b according to the received instruction for a superposed display.
