Solution Overview
Problem
Existing display control systems face complexity when managing multiple display devices with varying characteristics, leading to inconsistencies in image display and input handling across devices.
Innovation Solution
A coordinated display control system with multiple control devices that synchronize input events and image display across physically separate display devices, utilizing processors and notifiers to ensure uniform application execution and input handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single display controller manages multiple display devices, then system complexity is reduced, but input handling and image display consistency across devices deteriorates
Solution Approach 1:
The system divides the display control function into multiple independent display control devices, each managing specific display devices. This segmentation allows each controller to handle inputs and displays independently while maintaining consistency through coordination, thus improving input handling reliability without significantly increasing overall system complexity.
Solution Approach 2:
The application unit acts as an intermediary between multiple display control devices, receiving input events from one controller and distributing them to appropriate controllers. This mediator coordinate the operations of segmented controllers, ensuring consistent input handling and image display across multiple display devices while maintaining system scalability.
2Reliability
If multiple display control devices are used, then input handling and display consistency improve, but system complexity increases
Solution Approach 1:
Each display control device is designed with universal functionality to handle various input events and control different display devices. The application unit also serves multiple purposes by coordinating between controllers and managing application execution. This multi-functionality reduces the need for specialized components, thereby improving display consistency without proportionally increasing system complexity.
3Reliability
If input events are transmitted to all display control devices, then input handling reliability improves, but communication overhead and processing time increase
Solution Approach 1:
The system implements local quality by having the application unit intelligently route input events to specific display control devices based on which device should handle the input. Instead of universally distributing all input events to all controllers, the system directs events locally to the appropriate controller, thereby maintaining input handling reliability while reducing communication overhead and processing time.

AI summary
A display control system causes a plurality of display devices to display a same application in coordination among a plurality of display control devices each of the plurality of display control devices includes an obtainer that obtains an input event that is an input to an application according to an operation; a processor that outputs the input event obtained to at least another one of the plurality of display control devices; and a notifier that notifies an application unit of the input event when the processor obtains the input event from a display control device which has output the input event among the plurality of display control devices. The application performs processing that is common among the plurality of the display control devices and for causing the plurality of display devices to display the same application.
