Communication Terminal Drawing Control Unit for Stroke Data Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple functions in a communication terminal are started simultaneously, images shared between terminals can become difficult to display correctly due to display control issues, such as pop-up displays being obstructed by other functions.
Innovation Solution
A communication terminal and method that utilize a drawing control unit to process and superpose image layers, ensuring that images from one function can be properly displayed without interference from other functions, using a client-server architecture to manage and relay data between electronic whiteboards and other communication devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple functions sharing an image are started simultaneously in a communication terminal, then the terminal can execute multiple functions at the same timing, but an image displayed by one function becomes difficult to be viewed with a display control by the other function
Solution Approach 1:
The patent segments the display control by introducing a dedicated display control unit that operates independently from other function execution units. This display control unit specifically manages the display of images related to stroke data, separating the display control function from other concurrent operations to prevent interference and ensure proper visualization of shared images across multiple functions.
2Productivity
If multiple functions sharing an image are started simultaneously, then concurrent processing is enabled, but display control such as pop-up display becomes obstructed
Solution Approach 1:
The patent introduces a display control unit as an intermediary component that mediates between multiple concurrent functions and the display device. This intermediary unit specifically manages display operations for stroke data images, ensuring that display control reliability is maintained even when multiple functions execute concurrently, thereby preventing display obstructions and ensuring proper image visualization.
3Adaptability or versatility
If multiple functions share an image between communication terminals, then collaboration is enhanced, but display conflicts occur between functions
Solution Approach 1:
The patent segments the complex display control task by creating a dedicated display control unit that handles specifically stroke data display operations. This segmentation simplifies the overall system architecture by isolating display control complexity into a dedicated component, allowing multiple functions to share images between communication terminals without creating display conflicts, as the display control unit manages all display operations centrally and consistently.

AI summary
A communication terminal includes a first communication control unit configured to control a communication between the communication terminal and a first communication terminal via a delivery server; a second communication control unit configured to control a communication between the communication terminal and a second communication terminal; an acquisition unit configured to acquire content data transmitted between the communication terminal and the second communication terminal in the communication controlled by the second communication control unit, the first communication control unit sending the content data acquired by the acquisition unit to the delivery server; and a display control unit configured to control a display of an image based on content data delivered by the delivery server.
