Abstract
Focus plus context displays combine high-resolution detail
and lower-resolution overview using displays of different
pixel densities. Historically, they employed two fixed-size
displays of different resolutions, one embedded within the
other. In this paper, we explore focus plus context displays
using one or more mobile projectors in combination with a
stationary display. The portability of mobile projectors as
applied to focus plus context displays contributes in three
ways. First, the projector’s projection on the stationary
display can transition dynamically from being the focus of
one’s interest (i.e. providing a high resolution view when
close to the display) to providing context around it (i.e.
providing a low resolution view beyond the display’s
borders when further away from it). Second, users can
dynamically reposition and resize a focal area that matches
their interest rather than repositioning all content into a
fixed high-resolution area. Third, multiple users can
manipulate multiple foci or context areas without
interfering with one other. A proof-of-concept
implementation illustrates these contributions.
