By using Virtual Reality systems, or Virtual Environments (VEs), complex models can be designed and developed on a large scale and their features visualized, simulated, discussed and documented. These models are claimed to replace expensive physical models, and are highly appreciated for projects in architecture. People can, however, experience models of the same artifact differently for different visualization technologies. The study presented in this paper follows up a large earlier experimental study that compared experiences and performance of working with full-scale models in different VEs. Quantitative and qualitative data were collected from 286 different first-time users on size and colors. They worked alone or collaborated in pairs on a puzzle-solving task for approximately 20 minutes. The virtual models on a Rubik type puzzle were implemented as similarly as possible in the different VEs. Earlier results showed correlation between experiences, performance and immersiveness of technology. Data regarding how people experience size and color are examined for the first time in this paper. The results argue for the benefits of using large-scale systems for correctly estimating sizes, while for the benefits of desktop systems in order to better distinguish colors. Another important finding is the impact of working in pairs for making more accurate estimations. Accordingly, the conclusions are that the applied technical setting and also the presence of a partner and the communication flow between them influence understanding and assessing The influence of applied technologies on estimating 1(13) graphical representations 2(13) Conference Architectural Inquiries, Goteborg 2008 graphical representations. This favors further research highlighting the consequences of using a certain technology for specific projects in architecture, and indicates how certain technologies need to be improved. Furthermore, the paper discusses possible implications of not only technical, but also social, differences in users’ estimation of the usefulness of virtual models in architecture.
