Multi-Display Input Control for Seamless Cursor and Touch Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems with multiple display devices and input devices struggle to smoothly switch input between different input devices when cascade connected.
Innovation Solution
A display system configuration where the second controller transmits information to the first controller, allowing seamless switching between input devices by managing cursor and touch operations across multiple display units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices are cascade connected with respective input devices, then the system can support multiple computers and display devices, but switching input between different input devices becomes complex and difficult to operate smoothly
Solution Approach 1:
The first controller acts as an intermediary that receives information from the second controller about touch operations on the second display device. This mediator enables seamless input switching by translating touch operations from one display device to control another computer, resolving the complexity of direct multi-device input switching.
Solution Approach 2:
The first controller is designed to handle multiple functions: it controls the first computer directly through the first input device, and simultaneously controls the second computer through receiving and processing information from the second controller. This multi-functionality allows a single controller to manage multiple input devices and computers, simplifying the overall system operation.
2Adaptability or versatility
If each display device has its own input device and controller, then each device can operate independently, but coordinating input operations across cascade-connected devices increases system complexity
Solution Approach 1:
The system merges the control functions by having the first controller receive and process information from the second controller. This combination allows coordinated control across cascade-connected devices while maintaining independent operation capabilities, reducing overall system complexity through centralized information processing.
Solution Approach 2:
The second controller provides feedback about touch operations to the first controller, which then processes this information to control the appropriate computer. This feedback mechanism enables smooth coordination between controllers while maintaining independent device operation, as each controller can function autonomously while exchanging necessary control information.

AI summary
Provided is a display system that smoothly switches input from one input device to input from another input device when a plurality of display devices include respective input devices. The display system includes a first display device and a second display device. The first display device includes a first display unit, a first controller, and a first input device. The second display device includes a second display unit, a second controller, and a second input device. The first display unit displays a first image outputted from at least one first computer. The second display unit displays a second image outputted from at least one second computer. The first controller receives input of first information outputted from the first input device for operating the first and second computers. The second controller receives input of second information outputted from the second input device for operating the second computer. The second controller further transmits the second information received by the second controller to the first controller.
