Pointer-Driven Multi-Screen Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for medical institutions cannot simultaneously display multiple screens on a single high-resolution monitor, limiting user convenience and requiring multiple display devices for separate high and low-resolution images.
Innovation Solution
A display control method that allows a single display device to show multiple screens by using a pointer to switch between display areas, enabling seamless switching and intuitive operation by displaying one screen, then another, and adjusting the display range based on pointer movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices are installed to display different resolution screens simultaneously, then both high-resolution and low-resolution images can be displayed, but installation work and maintenance work increase
Solution Approach 1:
The patent combines multiple display functions (high-resolution image display and low-resolution operation image display) onto a single display device. The display device can switch between displaying one screen or two screens based on pointer position, eliminating the need for separate display devices and reducing installation and maintenance complexity.
Solution Approach 2:
The single display device is designed to perform multiple functions: it can display high-resolution images, low-resolution operation images, or both simultaneously depending on the pointer position. This multi-functional capability replaces what would traditionally require multiple dedicated display devices.
2Ease of operation
If only one screen is displayed on a single display device, then the device is simple to operate, but the user cannot see both screens simultaneously
Solution Approach 1:
The display device dynamically changes its display mode based on pointer position. When the pointer is in the first area, only the first screen is displayed for simplicity. When the pointer moves to the second area, the system switches to displaying both screens simultaneously, providing the needed information without complicating the user's interaction.
Solution Approach 2:
The pointer acts as an intermediary that triggers the display mode change. By detecting pointer position, the system automatically decides whether to show one screen or two, mediating between the user's interaction and the display output to balance simplicity and information availability.
3Loss of information
If two screens are displayed simultaneously on a single display device, then both screens are visible, but the display area for each screen is reduced
Solution Approach 1:
The display screen is segmented into different display modes: single-screen mode for full-area display and dual-screen mode for simultaneous display of both screens. The system segments the display area dynamically based on the pointer position, allocating full area to one screen or dividing it to show both screens when needed.

AI summary
Provided are a display control method by which the user can cause, with enhanced ease of use, one display device to display multiple screens, and a computer program, a display control device, and an image display system. A working area generation unit generates multiple areas corresponding to multiple display areas displayed on a display screen and positions the generated areas in a working area. When only a display area A (parent screen) is displayed on the display screen (when the PinP function is disabled), a pointer position monitoring unit determines whether the pointer position has moved from an area a to an area b and outputs the determination to a simultaneous display command generation unit. If so determined, the simultaneous display command generation unit outputs a PinP function enable command to a display device.
