Rationale, Design and Implementation of a Computer-Vision based Interactive E-Learning System

This article presents a schematic application of computer vision technologies to e-learning that is synchronous, Peer-to-Peer-based, and supports instructor's interaction with noncomputer teaching equipments. The article first discusses the importance of these focused elearning areas, where the properties include accurate bidirectional interaction, low cost hardware; system portability and versatile vision technology are emphasized. In the subsequent sections, we present some results aiming to achieve these goals. In particular, we highlight the most recent advancements in the interactive PTZ camera control from both the instructor and remote student. We also illustrated how these results have successfully addressed the challenges.
