The elegance of using virtual interactive lenses to provide alternative visual representations
for selected regions of interest is highly valued, especially in the realm of visualization …

Most of the maps used today are what we call pan-scalar maps, ie interactive zoomable
applications comprised of numerous maps of a particular area at different zoom levels (ie …

Map applications for smartwatches present new challenges in cartography, a domain in
which large display sizes have significant advantages. In this paper, we introduce …

Multi-scale navigation interfaces were originally designed to enable single users to explore
large visual information spaces on desktop workstations. These interfaces can also be quite …

Shared displays are well suited to public viewing and collaboration, however they lack
personal space to view private information and act without disturbing others. Combining …

Interactive lenses have proven to be useful for many visualization applications where
