Message Display Controller Priority Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In group chat settings, frequent message posting leads to continuous scrolling on terminal devices, potentially causing users to overlook high-importance messages due to automatic scrolling mechanisms that do not differentiate between message importance.
Innovation Solution
A terminal device and information processing apparatus system that determines message importance based on display time and sends importance information, allowing the display controller to execute different processing for high-importance messages, such as preventing automatic scrolling until the user confirms the message, and displaying high-importance messages in a distinct manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic scrolling is executed for every new message, then message display efficiency is improved, but high-importance messages may be overlooked
Solution Approach 1:
The patent applies local quality by differentiating the display treatment based on message importance. High-importance messages receive special treatment (preventing automatic scrolling, displaying at top position) while ordinary messages follow the standard scrolling behavior. This selective differentiation ensures that critical messages are not overlooked while maintaining efficient scrolling for regular messages.
Solution Approach 2:
The system changes the display parameter (scrolling behavior) based on the importance parameter of messages. When a high-importance message is detected, the scrolling parameter is modified to prevent automatic scrolling or to reposition the message at the top. This dynamic parameter adjustment resolves the contradiction by adapting the display behavior to message priority.
2Reliability
If different processing is applied to high-importance messages, then message importance recognition is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary action by determining message importance before displaying the message. The importance level is assessed in advance, and based on this assessment, the display controller pre-determines the appropriate processing mode (standard scrolling vs. special handling). This preliminary classification simplifies the overall control logic by making the decision tree explicit and manageable.
Solution Approach 2:
The patent applies local quality by differentiating the display treatment based on message importance. High-importance messages receive special treatment (preventing automatic scrolling, displaying at top position) while ordinary messages follow the standard scrolling behavior. This selective differentiation ensures that critical messages are not overlooked while maintaining efficient scrolling for regular messages.

AI summary
A terminal device includes a first communication device, a display device, and a first control device. The first control device functions as a display controller. The display controller allows the display device to display a first massage in a message display area of the display device. When the first message is not a high-importance message and the display controller then receives through the first communication device a second message sent from the information processing apparatus, the display controller allows the display device to execute first processing of scrolling a displayed image in the message display area and displaying the second message in the message display area. When the first message is a high-importance message and the display controller then receives the second message through the first communication device, the display controller allows the display device to execute second processing different from the first processing.
