Implementation of Interactive E-learning System Based on Virtual Reality

摘要

VR (Virtual Reality)-based e-learning applications have become an important part of the educational program in kindergarten as well as in the National Children's Library (NLCY), in Republic of Korea. As kindergarten pupils and their teachers use the VR-based e-learning system, they can be more visually aware of ongoing course materials and more intuitively aware of getting quick response from event handling on screens. However, the existing VR-based e-learning system consists of complex equipment such as a large screen and beam projector to show the actual scene in 3D, more than two PCs, a forward camera to detect the pupils' movement, and a rear camera to capture the pupils' image. In this paper, we introduce a VR-based interactive e-learning system, which is implemented to enable kindergarten pupils to quickly experience a better sense of reality and immersion in a virtual reality environment without regard to the floor space. Applying technologies such as RTSP (Real Time Streaming Protocol) to the VR-based interactive e-learning system allows users to display the same view on different remote display devices, allowing separate users to share interactive events for collaboration.
