Wayfinding techniques for multiscale virtual environments

Abstract

Não possui resumo em português

Way nding in multiscale virtual environments can be rather complex, as users can and sometimes have to change their scale to access the entire environment. Hence, this work focuses on the understanding and classi cation of information needed for travel, as well as on the design of navigation techniques that provide this information. To this end, we rst identi ed two kinds of information necessary for traveling e ectively in this kind of environment: hierarchical information, based on the hierarchical structure formed by the levels of scale; and spatial information, related to orientation, distance between objects in di erent levels of scale and spatial localization. Based on this, we designed and implemented one technique for each kind of information. The developed techniques were evaluated and compared to a baseline set of travel and way nding aid techniques for traveling through multiple scales. Results show that the developed techniques perform better and provide a better solution for both travel and way nding aid.
