In this paper, we propose the Interactive 3D BreakAway Map (I3BAM), an extension of the wellknown Worlds In Miniature [6]. The I3BAM supports user navigation in virtual buildings as a navigation aid, but also provides a means of examining any floor of a virtual building without having to necessarily navigate it. The aid presents multiple views of a virtual(More)
