Focus Plus Context Screens: Displays for Users Working with Large Visual Documents
March 8, 2002
In this talk, I will present Focus
plus context screens. Focus plus context screens are wall-size
low-resolution displays with an embedded high-resolution display
region. Image content is displayed such that the scaling of the
display content is preserved, while its resolution varies according
to which display region it is displayed in. Focus plus context
screens allow users to view details of a document up close, while
simultaneously seeing peripheral parts of the document in lower
resolution. I will present our prototype that seamlessly integrates
an LCD with a projection screen, demonstrate four application
scenarios, and report the results of an experimental comparison
with competing visualization techniques.
Patrick Baudisch
is a research scientist at Xerox
PARC. His research interests include user interface design,
information visualization, and focus
plus context screens. While at GMD-IPSI, Baudisch was a member
of the digital libraries
group. His dissertation
is in the area of dynamic information filtering and resulted
in the TV recommendation systems TV
Scout. Baudisch worked as a guest researcher at the GroupLens
project at the University on Minnesota. Baudisch holds a PhD
in Computer Science from the Darmstadt
