Mobile Video Conferencing With Bidirectional Digital Annotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conferencing technologies limit mobile users' ability to participate in interactive and collaborative sessions while on the move, as they require stationary devices and lack efficient digital annotation and video sharing features across mobile platforms.
Innovation Solution
A mobile video conferencing technique that enables bidirectional sharing of live video and digital annotations between local and remote mobile devices, allowing users to transmit and display selected video streams, resize annotations, and collaborate on shared content, even when users are moving, using integrated front and rear video capture devices and touch-sensitive displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video conferencing is conducted using mobile devices, then mobility and accessibility are improved, but device complexity and system requirements increase
Solution Approach 1:
The mobile device is designed to perform multiple functions: capturing video from front and rear cameras, displaying received video streams, enabling user interaction through touch input, and transmitting data over networks. This multi-functionality allows a single mobile device to replace traditional stationary video conferencing equipment, achieving mobility while managing complexity through consolidation
Solution Approach 2:
The system combines video capture, video display, touch input processing, and network communication into an integrated mobile video conferencing system. The front video capture device, rear video capture device, display, and input device are merged into a single portable unit, enabling conferencing functionality while maintaining ease of operation
2Adaptability or versatility
If digital annotation features are added to video conferencing, then collaboration capability is improved, but data processing complexity increases
Solution Approach 1:
The system pre-processes and transmits video streams from both local and remote devices before annotation occurs. By having video streams readily available and pre-positioned on the display, the system reduces processing complexity during the annotation interaction, allowing users to collaborate efficiently without real-time processing delays
Solution Approach 2:
The display acts as an intermediary between the video streams and the user's annotation input. It receives video data, renders it for viewing, and captures touch input coordinates, then transmits annotation data back to the remote device. This intermediary role simplifies the data processing architecture by centralizing the coordination of video and annotation data flow
3Reliability
If multiple video streams are shared bidirectionally, then communication quality is improved, but network bandwidth requirements increase
Solution Approach 1:
The system implements bidirectional video streaming where both local and remote devices transmit and receive video streams simultaneously. This partial redundancy ensures that both parties have full video capability, improving communication quality and reliability. The system manages bandwidth by optimizing stream transmission and utilizing the mobile network infrastructure efficiently

AI summary
A local user of a local mobile device is allowed to participate in a video conference session with a remote user of a remote mobile device. Live video can be shared between and collaboratively digitally annotated by the local and remote users. An application can also be shared between and collaboratively digitally annotated by the local and remote users. A digital object can also be shared between and collaboratively digitally annotated by the local and remote users.
