Presence Notification for Video Projection Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Demand-based messaging systems, such as instant messaging, pose a risk of inadvertently disclosing confidential or personal information when used while projecting video, as messages received during presentations are often displayed on the computer screen, potentially embarrassing the recipient.
Innovation Solution
A method and computer system that monitor an auxiliary output port for a video signal, detect video projection status, and report it to the messaging system, allowing for the blocking of messages from being displayed on the auxiliary output port and sending notifications to the sender.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If messages are displayed on the computer screen during video projection, then communication functionality is improved, but privacy security deteriorates due to inadvertent disclosure of confidential information
Solution Approach 1:
The system performs preliminary detection of video projection status by monitoring the auxiliary output port before messages are displayed. When video projection is detected, the system proactively blocks message display on the auxiliary output port, preventing the harmful effect before it can occur.
Solution Approach 2:
The system continuously monitors the auxiliary output port for video signals and uses this feedback to dynamically control message display. When a video signal is detected, the system adjusts its behavior by blocking message display, and when no video signal is present, normal message display resumes.
2Object-affected harmful factors
If video projection status is manually monitored and controlled, then privacy security is improved, but device complexity increases
Solution Approach 1:
The system automatically monitors the auxiliary output port for video signals and self-regulates message display without requiring user intervention. The presence notification system autonomously detects video projection status and blocks or allows message display accordingly, eliminating the need for manual monitoring or user configuration.
Solution Approach 2:
The presence notification system acts as an intermediary between the video projection function and the messaging system. It monitors the auxiliary output port and mediates message display by blocking messages when video projection is detected, providing a automated solution that reduces complexity compared to manual monitoring approaches.

AI summary
In accordance with one embodiment of the present invention, a method is provided for communicating a presence notification to an end-point of a demand-based messaging system. The method includes monitoring an auxiliary output port for a video signal; detecting a video signal on the auxiliary output port; and reporting a video projection status to the end-point. In additional or alternative embodiments of the method, the method may include receiving a message from the end-point and blocking the message from being displayed on the auxiliary output port. In yet another additional or alternative embodiment of the method, the method may include sending a message to the end-point indicating that the message has been blocked.
