Message Display Control for Video Output Connection Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During presentations, confidential or personal messages are inadvertently displayed on external video output devices, causing embarrassment and potential information disclosure, as users often fail to manually disconnect or switch screens in time.
Innovation Solution
A messaging system that determines the output status of a device connected to a video output device and adjusts message display accordingly, using an output status sensing module and estimating module to detect and manage the display of messages based on whether the device is projecting, thereby preventing unintended information disclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If messages are displayed on the screen during presentations, then communication functionality is maintained, but confidential information may be inadvertently disclosed to unintended audiences
Solution Approach 1:
The system performs preliminary detection of presentation mode before messages are displayed. By detecting video output device connection status in advance and setting message reception restrictions proactively, the system prevents confidential information from being displayed during presentations while still allowing normal communication when not in presentation mode.
2Reliability
If the system automatically detects presentation mode to prevent message display, then information security is improved, but system complexity increases due to additional detection mechanisms
Solution Approach 1:
The system uses the video output device connection status as an intermediary indicator to infer presentation mode. Rather than implementing complex presentation detection algorithms, the system leverages the existing video output interface connection state as a reliable proxy for determining whether a presentation is in progress, thereby maintaining information security without significantly increasing system complexity.
3Object-affected harmful factors
If message display is restricted during presentations, then unintended information disclosure is prevented, but user convenience deteriorates due to manual intervention requirements
Solution Approach 1:
The system automatically detects whether the information processing device is in presentation mode by monitoring video output device connection status, and autonomously applies message reception restrictions without requiring user intervention. This self-service approach eliminates the need for users to manually switch modes or remember to disable messages during presentations, thereby preventing unintended information disclosure while maintaining ease of operation.

AI summary
Embodiments relate to a method, apparatus and program product for processing messages. The messaging system includes a plurality of information processing devices communicating via a network and an output status determining unit for verifying a first information processing device is connected to a video output device. It also includes a message processing unit configured to provide a message on a first or a second information processing device. The message is provided in a certain manner based on information provided by the output status determining unit.
