Talk: Real-time PDF Commenting and Audience Interacting Online System

In common practice, instructors always tend to use generic computer-aided tools such as Slideshow or Word Processing software to facilitate their teaching in class. However, when they want to highlight few points, sketch some drawings during teaching or even type few texts in real time, it seems that those tools cannot provide a convenient way for them to do so. Instead, many instructors migrate to draw on the whiteboard or even use visualizer to write on hard copy of notes. Thus, I would like to propose an online system that can allow real-time typing, simple drawing and highlight on PDF file online.

Besides, it is now a trend to have both face-to-face teaching together with online LIVE teaching. However, it is a common practice that those real-time teaching platform always show presenter’s face through very small window when screen sharing is made. It cannot deliver any cordial feeling to our students. To better handle this issue, a scalable portrait view via webcam will be added to either left or right side of the system so that audience can see both our face and gestures during teaching.

On top of this, students always hesitate to ask questions during the class but they are pleased to ask through text messages. Therefore, I would like to incorporate a announcement and chatroom interface shown side-by-side with PDF commenting area to enable audience silently reflecting their doubts.
