8. ¡ Geometrical
Zooming
zooms
the
geometry
of
the
view
¡ Semantic
Zooming
zooms
the
meaning
of
the
view:
§ Online
maps:
only
show
roads
and
rivers
as
the
viewpoint
gets
closer
§ Show
the
right
level
of
detail
for
the
zoom
point
§ Apply
lenses
to
the
data

9. ¡ Spatial
metaphors
may
require
additional
cognitive
load…

¡ Recalculation

16. ¡ Big

requires
new
tools
for

and

access
¡ Semantic
Zooming
supports
multi-­‐level

of

¡ Lenses
support
dynamic

of
