Display Control Device for Multi-Terminal Pointer Responsiveness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window control systems face delays and performance deterioration when handling multiple three-dimensional targets, particularly in applications like airplane control systems, due to the processing load and lack of specific methods for handling pointer movement and control across multiple operation terminals.
Innovation Solution
A display control system that separates pointer and application screen processing into distinct units, with an image synthesis unit combining these to provide a seamless display, and includes tables to manage rights and prevent simultaneous operation of applications by multiple operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pointer control and application processing are handled by the same information processing terminal, then the system structure is simple, but pointer display and control are delayed due to processing load from displaying many three-dimensional polygonal targets
Solution Approach 1:
The patent divides the information processing terminal into two separate processing units: a first processing unit dedicated to pointer control and a second processing unit dedicated to application processing. This segmentation allows pointer operations to be processed independently from application rendering, eliminating pointer display delays caused by heavy application processing loads while maintaining a relatively simple overall system structure.
2Device complexity
If pointer control and application processing are handled by the same information processing terminal, then hardware configuration is simple, but the original real-time performance of state display deteriorates due to increased load from pointer control
Solution Approach 1:
The patent segments the processing functions into two separate processing units, allowing each unit to specialize in its specific task. The first processing unit handles pointer control with low latency, while the second processing unit handles application rendering. This segmentation prevents pointer control from adding load to the application processing pipeline, thereby preserving the real-time performance of state display while maintaining a relatively simple hardware configuration.
3Adaptability or versatility
If multiple operators simultaneously operate windows on a shared screen display device, then multi-user operation is enabled, but specific methods for pointer movement and window control across multiple terminals are lacking
Solution Approach 1:
The patent implements a window control rights management mechanism that allows multiple operators to simultaneously operate windows on a shared screen display device. Each operator's terminal is assigned specific window control rights, enabling universal multi-user operation while maintaining clear authorization rules. The system manages pointer movement and window control across multiple terminals through a standardized rights-based framework, making the system both versatile and easy to operate.

AI summary
The prompt responsiveness and operability of pointer display and pointer control is ensured. A display control device has: a first information processing terminal drawing a pointer corresponding to each of input operation devices on a pointer screen on the basis of an operation quantity input from each of the input operation devices; a second information processing terminal drawing a working state of an application on an application screen in accordance with the input instruction information input from each of the input operation devices; and an image synthesis unit that creates a synthesized image by superimposing each of the two screens on the other and that outputs the image to a display device.
