CollaborativeComputingLab

A Prototype of Live Mobile Learning System (using RTMP)

The project was developed as part of research activities at the Collaborative Computing Lab (CCL), Hongik University.

Our goal is to provide a mobile learning experience comparable to real-world classroom lectures.

Key Features

  • Real-time audio / video lecture streaming
  • Multi-room lecture support
  • Live chat for real-time interaction between instructors and students
  • Annotatable PDF slides and a whiteboard
  • User-Adjustable UI that allows instructors to dynamically control the screen ratio between slides and the whiteboard
