Communication Device Selective State Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, the delay in receiving data due to communication speed or data traffic can lead to users becoming anxious as old information is displayed when data is cached, and displaying a waiting state may increase the frequency of updates, thereby deteriorating the purpose of displaying information based on the received data.
Innovation Solution
A communication system where the data receiving device decides whether to display state information based on the type of information being displayed, allowing it to maintain the essential function of displaying information without causing user anxiety, by optionally displaying state information in place of the data or maintaining the data display when in a waiting state for certain types of information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the data receiving device displays information based on cached data, then the display speed is improved, but the information may be outdated and cause user confusion
Solution Approach 1:
The system performs preliminary actions by caching data in advance and executing temporary processes before receiving updated data. This allows the device to prepare display content ahead of time, improving display speed while maintaining the ability to update when new data arrives without causing user confusion through outdated information
Solution Approach 2:
The system dynamically switches between displaying cached information and waiting for updated data based on reception status. The display control adapts its behavior in real-time, showing cached content when appropriate and transitioning to waiting state or updated content when data is received, thus balancing speed and information freshness
2Ease of operation
If the data receiving device displays waiting state information frequently, then user anxiety is reduced, but the essential function of displaying information based on received data is deteriorated
Solution Approach 1:
The system applies different display qualities to different regions or contexts: waiting state information is displayed selectively in certain situations while essential information based on received data is displayed in others. This local differentiation ensures user anxiety is reduced without compromising the essential information display function
Solution Approach 2:
The system displays waiting state information partially rather than continuously or excessively. Waiting state display is applied only when necessary to reduce user anxiety, while maintaining the primary function of displaying essential information based on received data, thus avoiding deterioration of information display quality

AI summary
There is provided a communication system in which a data sending device and a data receiving device are connected to each other, the data sending device has a function of sending data to be displayed to the data receiving device and the data receiving device has a function of receiving the data to be displayed. In the communication system, the data receiving device includes a display on which information is displayed, an information display control unit that displays information based on the data to be displayed on the display if the data receiving device receives the date to be displayed from the data sending device, and a state display control unit that decides whether to display state information indicating that the data receiving device is in a waiting state for the data to be displayed when the data receiving device changes to the waiting state, in accordance with a type of the information displayed on the display.
