Overview
Developed a revolutionary browser-based wireless screen casting platform eliminating software installation while enabling unlimited simultaneous screen sharing to TouchIT Interactive LED displays.
Key Responsibilities & Achievements
- Eliminated software installation requirements for screen casting
- Built unlimited simultaneous screen sharing capabilities
- Achieved cross-platform compatibility (PC, Mac, Chromebook, Linux)
- Implemented revolutionary browser-based wireless casting solution
- Created real-time multi-user collaboration features
Technical Implementation
The platform leverages React frontend with Node.js backend deployed on Digital Ocean infrastructure, utilizing OpenVidu's WebRTC framework for robust peer-to-peer screen sharing capabilities. The web application provides universal compatibility across Chrome and Firefox browsers on multiple operating systems without requiring client-side software installation. The casting functionality utilizes OpenVidu's WebRTC implementation to establish direct connections between browser clients and the Progressive Web Application (PWA) running on TouchIT LED displays. This PWA approach eliminates the need for native Android app installation while providing full casting receiver capabilities through modern web standards. The PWA receiver handles multiple simultaneous incoming streams using Fabric.js canvas for efficient stream rendering and real-time switching capabilities. The platform supports both full-screen and application-specific casting modes, with Fabric.js providing smooth canvas-based display management and interaction handling. Remote casting capability extends beyond local network limitations through OpenVidu's signaling server infrastructure, enabling distributed collaboration scenarios such as remote learning and support. The system maintains consistent performance across various network conditions by leveraging OpenVidu's adaptive streaming and connection management. The multi-casting architecture supports unlimited simultaneous participants through OpenVidu's scalable WebRTC infrastructure, implementing efficient stream management and display organization to handle large-scale collaborative scenarios typical in educational institutions. The React frontend provides responsive interfaces for both casting clients and PWA receivers, while Node.js orchestrates session management and participant coordination.
