Video Conference Window Activator Using Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video calling technologies often lead to inefficient bandwidth usage due to continuous transmission of video and audio signals, even when communication is not active, which can result in a less natural communication experience and increased costs.
Innovation Solution
Implementing a system that detects the presence of local and remote watchers using sensors, cameras, and facial recognition software to transmit video and audio only when necessary, and transmitting a single captured image when no active communication is occurring, thereby reducing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video and audio signals are transmitted continuously to maintain constant communication availability, then communication readiness is improved, but bandwidth consumption increases
Solution Approach 1:
The system transmits video and audio signals periodically based on detected user presence and activity states rather than continuously. The communication system activates transmission only during periods when users are present and engaged, and switches to still image transmission or suspension during periods of inactivity, creating a periodic transmission pattern that maintains communication readiness while reducing overall bandwidth consumption.
Solution Approach 2:
The transmission mode dynamically adjusts based on real-time detection of user presence and activity. The system transitions between different transmission states (full video/audio, still images, or no transmission) according to the detected state of users, making the communication system adaptive to actual usage conditions rather than operating in a fixed continuous mode.
2Ease of operation
If video and audio transmission is activated immediately upon call initiation to ensure natural communication, then communication naturalness is improved, but bandwidth is wasted during periods of silence
Solution Approach 1:
The system uses sensors and detection mechanisms to continuously monitor user presence and activity states, providing feedback to the transmission control logic. Based on this feedback, the system intelligently determines when to activate full video/audio transmission and when to switch to still image or suspend transmission, eliminating bandwidth waste during silent periods while maintaining natural communication flow when users are actively engaged.
Solution Approach 2:
The communication system automatically adjusts its transmission behavior based on detected user states without requiring manual intervention. The system self-regulates transmission modes by monitoring presence and activity information, activating full transmission only when needed and switching to lower-bandwidth modes during inactivity, thereby eliminating waste while preserving communication naturalness.
3Loss of energy
If a single still image is transmitted instead of video and audio signals during inactivity, then bandwidth consumption is reduced, but communication capability is limited
Solution Approach 1:
The transmission capability dynamically adapts between different modes (full video/audio, still images, or suspension) based on detected user presence and activity states. This dynamic adjustment allows the system to provide full communication capability when needed while reducing to minimal still image transmission during inactivity periods, thereby reducing bandwidth consumption without permanently limiting communication versatility.
Solution Approach 2:
The system periodically monitors user states and switches between transmission modes accordingly. During active periods, full video/audio transmission provides complete communication capability, while during inactive periods, the system transitions to still image transmission or suspension. This periodic switching maintains communication versatility when needed while achieving bandwidth savings during inactivity.

AI summary
A method for activating a video conference between at least one local watcher using a local communication enabled device and at least one remote watcher using a remote communication enabled device is provided. The method may include detecting the at least one local watcher and the at least one remote watcher at each respective communication enabled device. The method may also include transmitting a video signal and an audio signal between the local communication enabled device and the remote communication enabled device based on the detecting of both the at least one local watcher and the at least one remote watcher at each respective communication enabled device. The method may further include transmitting a single captured image between the local communication enabled device and the remote communication enabled device based on the detecting of one of the at least one local watcher and the at least one remote watcher.
