 In the future, video
displays will be everywhere, permeating all of our environments, at home, at
work, or in public spaces. What kinds of content would we want to see on these
ubiquitous displays? We have begun to explore three different contexts in which
these displays might be used, with a different application driving the displays
in each context:
UniCast: a peripheral display in an
individual's office that can display a wide range of interesting—but not
extremely urgent or important—content that a person may not actively seek out
on his or her primary computer workstation, e.g., events of interest, artwork,
cartoons, and a range of X-of-the-day Web sites whose content changes daily.
Users create a profile for this content, which can then be used by displays in
other contexts.
GroupCast: a large display in a casual
group setting, such as a break area, where the content is selected based on the
combined profiles of the group assembled (or walking by) the display at any
given time—people nearby are identified by their infrared badges. The goal of
GroupCast is to foster a stronger sense of community among a group of
collocated workers, by creating new informal conversation opportunities based
on mutual interests.
OutCast: a peripheral display mounted
on the exterior of an individual's office that contains content a person may
want to communicate about him- or herself to passers-by, such as the office
occupant's current location, project descriptions, online demonstrations and
interests. As with GroupCast, some portion of an individual's UniCast profile
will likely be used in this context.
These three applications originated independently, but over
time, we expect that there will be considerable overlap between the profiles
used in each context.
