Multi-scale collaborative virtual environments (MCVEs) provide an important platform for many 3D application domains as they allow several users to cooperate in a virtual environment (VE) at different scale levels, ranging from magnified detail views to minified overall views. However, in such MCVEs, the natural relations between a user's self-representation, i.e., her virtual body, and the environment in terms of size, scale, proportion, capabilities, or affordances are subject to change during the interaction. In this paper we describe how the type of the environment, virtual self-representation of our body, as well as presence of other avatars affects our estimation of dominant scale, i.e., the scale level relative to which we make spatial judgments, plan actions and interpret other users' actions in MCVEs. We present a pilot study, which highlights the problem domain, and two psychophysical experiments, in which we analyzed how the different factors in MCVEs affect the estimation of dominant scale and thus shape perception and action in MCVEs. Our results show an effect of the above-mentioned aspects on the estimation of dominant scale. In particular, our results show interpersonal differences as well as a group effect, which reveals that participants estimated the common scale level of a group of other avatars as dominant scale, even if the participant's own scale or the environment scale deviated from the other avatars' common scale. We discuss implications and guidelines for the development of MCVEs.
