This paper describes the design process for prototyping a three-dimensional desktop virtual environment. The design model encompasses evaluation as the central part of the design process. Design implications derived from a formative evaluation are described in terms of navigation, object interaction and affordance perception. The design process is described in the context of prototyping an application for teaching safety information. The evaluation results suggest that user-centred design and attention to usability issues are not always sufficient to support the user for learning purposes. Although conventional human-computer interaction evaluation methods partially address the evaluation of three-dimensional applications, results showed that they are relevant for designing this type of teaching environments, particularly during early stages.
