Previous studies about the use of 3D models for information search have not shown a clear advantage over 2D or textual user interfaces. This paper describes an experimental study focused on initial overview and information browsing tasks, that we consider to be more adequate to take advantage of 3D exploration. To this end, a 3D Explorer prototype was developed and tested by experimental subjects. The 3D usability evaluation provided interesting design concepts and feedback, while the statistical evaluation of results showed significant speed advantages over a more classic interface, and a good potential for future improvements.
