A Design Model for 3D Desktop Virtual Environments
A model for designing desktop virtual environments is presented. The model considers principles of user-centred design and leaner-centred design to integrate a design process that better meets the needs of the learner. The design process is illustrated in the context of prototyping a virtual environment for teaching safety information. Main stages of the design process are described in detail and practical recommendations are given. Design implications derived from evaluation are described in terms of virtual environments usability issues. Results suggest that principles of user-centred design and learner-centred design should be considered as complementary paradigms in order to design usable applications for learning.
