Multi-Touch Display Input Selection with OS Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for multi-monitor touch-screen environments face challenges in accurately determining which monitor receives touch input and ensuring users recognize the status of their input, often requiring dedicated controllers and applications, and lack user recognition of input enablement.
Innovation Solution
An information processing apparatus with a control unit that selects and transmits touch data from multiple touch-screen devices, providing selection status information to each device and the operating system, allowing users to recognize their input status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated controller and dedicated application program are used for assigning terminal IDs to handwriting input information from multiple users, then the system can handle simultaneous touch input on multiple monitors, but the device complexity increases
Solution Approach 1:
The patent makes the operating system itself universal by enabling it to directly handle touch input from multiple monitors without requiring dedicated controllers or applications. The OS uses existing APIs and resources to assign terminal IDs and process touch data, allowing any standard application to receive touch input through the OS's unified mechanism.
Solution Approach 2:
The patent extracts the touch input handling functionality from dedicated controllers and applications, concentrating it within the operating system core. By implementing terminal ID assignment and touch data routing within the OS itself, the system eliminates the need for separate dedicated hardware controllers and specialized application programs.
2Ease of operation
If touch input handling is centralized in the operating system without status feedback, then the system simplicity is maintained, but users cannot recognize whether their input is enabled
Solution Approach 1:
The patent implements feedback by having the operating system transmit selection status information back to the touch-screen display devices. This allows users to visually recognize whether their monitor is currently enabled for touch input, providing immediate feedback about the system state without requiring complex user interaction.
Solution Approach 2:
The patent uses visual status indicators (such as highlighting or color changes on the display) to communicate the selection status to users. When a monitor is selected for receiving touch input, it is visually distinguished from non-selected monitors, providing intuitive status feedback through display characteristics.
