Abstract
Intelligent environments enable users to receive informa-
tion from a variety of sources, i.e. from a range of dis-
plays embedded in those environments. From a services
perspective delivering presentations to users in such an
environment is not a trivial task. While designing a
service it is, for example, not clear at all which displays
will be present in the speci¯c presentation situation and
which of those displays might be locked by other ser-
vices. It is further unclear if other users are able to see
the presentation, which could cause problems for the
presentation of private information in a public space.
In this paper we propose a solution to this problem
by introducing the concept of a presentation manager
that provides services with an abstraction of the avail-
able displays. The presentation manger is able to detect
con°icts that arise when several users and services try
to access the same display space and provide strategies
to solve these con°icts by distributing presentations in
space and time. Finally, we will report our experiences
that were gained within an intelligent environment with
a presentation manager managing parallel presentations
from a navigation and a shopping service.
