A design framework for interaction in 3D real-time learning environments

Currently, deficiencies in learning environments concern concepts, consistency, screen layout, interface design, navigation strategies, low-level of multimedia based interactions. In order to enlarge the communication capabilities in a learning environment, it is essential to focus on two fundamental aspects in the user interface: information presentation and information access. Pursuing this aim, the paper discusses the design of hypermedia systems in its own unity of concept and design modeling for learner-beneficial support by the user interface. In relation to these explanations, it presents a learning system that benefits from the research about both the consideration of human visual and acoustic perception in the user interface for learning and the sufficient visualization of multidisciplinary contents for engineering educational activities, especially by 3D models, 3D animations and simulations, which facilitate the learner's immersion in a hidden world.
