Solution Overview
Problem
Conventional systems provide limited mechanisms for controlling source computers connected to a video processor, requiring users to perform cumbersome tasks such as entering IP addresses and extensive mouse clicks to switch between source computer control and system control.
Innovation Solution
A control computer with an interface that uses mouse position information to efficiently switch between video processor mode and source computer mode, allowing users to control source computers by determining whether the mouse pointer is within a source computer window, enabling seamless operation and manipulation of individual source computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional control mechanisms are used to switch between source computer control and system control, then control functionality is provided, but user interaction becomes cumbersome requiring extensive mouse clicks and IP address entry
Solution Approach 1:
The system pre-establishes the control environment by displaying multiple source computer windows on the video processor interface before user interaction. The mouse position tracking and mode detection mechanisms are pre-configured to automatically recognize when the cursor enters or exits window boundaries, eliminating the need for users to manually initiate mode switching procedures or enter IP addresses.
Solution Approach 2:
The system performs automatic mode detection and switching based on mouse position relative to window boundaries. The video processor continuously monitors cursor coordinates and autonomously determines whether to switch between source computer control mode and system control mode without requiring user intervention,从而使 the system serves itself in managing control state transitions.
2Adaptability or versatility
If multiple control mechanisms are provided for source computer control, then control flexibility is improved, but system complexity increases
Solution Approach 1:
The video processor interface serves multiple functions simultaneously: it displays video output from multiple source computers, provides system control capabilities, and enables direct source computer control through window-based interaction. A single unified interface handles all these functions by detecting mouse position and automatically switching modes, eliminating the need for separate control systems for each function.
Solution Approach 2:
The system merges source computer control functionality and system control functionality into a single integrated interface. By combining window display, mouse position tracking, and automatic mode switching into one unified system, the patent reduces the number of separate control mechanisms while maintaining full control flexibility across both source computers and video processor operations.
3Ease of operation
If manual control switching is required, then system control precision is maintained, but ease of operation deteriorates
Solution Approach 1:
The patent replaces manual mechanical control switching (clicking buttons, entering commands) with an automated detection system that monitors mouse position coordinates. The system uses software-based detection of cursor location relative to window boundaries to automatically trigger mode changes, substituting physical interaction mechanisms with intelligent position-based detection and automatic response.
Data Source
AI summary
Methods and apparatus are provided for efficiently controlling source computers connected to a display system. A control computer is connected to one or more source computers and video output is shown on a display system. A mouse and associated input devices may operate in video processor mode or source computer mode based on mouse x-coordinate and y-coordinate position information. Other modes such as control computer mode are also possible. In particular instances, a mouse and associated input devices operate in source computer mode to control a particular source computer when the mouse pointer position resides within one of the source computer windows. A mode of operation may switch based on a change in mouse position.
