Introducing Adaptive Hypermedia Techniques in 3D Educational Virtual Environments

Highly interactive learning environments, such as 3D Educational Virtual Environments can help people in learning through direct experience by visualizing concepts and performing tasks in a reproduction of the real world or in completely fictional worlds that are suited to the learning task. For these applications, adaptivity can play an important role in increasing the effectiveness of the learning process and usability of the interface. In this paper, we present a system that is able to deliver personalized learning content in 3D Educational Virtual Environments by exploiting techniques that extend those employed the field of Adaptive Hypermedia by the well-known AHA! system. Moreover, we present a case study in which the proposed system is used to build an adaptive 3D application that teaches students how to build interactive 3D graphics content using the eXtensible 3D (X3D) ISO standard language.
