Many Ubiquitous computing applications can be considered
as planning and acting problems in environments characterised
by uncertainty and partial observability. Such
systems rely on sensor data for information about their environment
and use stochastic or probabilistic reasoning algorithms
to infer system state from sensor data.
We propose a domain modelling technique that characterises
the sensor and actuator infrastructure and the set of
system states in Ubicomp application domains. We capture
the location and geometry of all domainmodel elements and
use these spatial properties to tailor system state determination
to reflect the quality and spread of the sensor and
The domain model is used to support the development of
Ubicomp applications and allows us calculate the degree
of observability that exists over the state space in the environment.
The degree of observability over the state space
can act as an input into determining the state inference and
action selection algorithms used in Ubicomp systems.
In this paper we present the design of our Ubicomp domain
model. We show that the proposed model contains
information necessary to support Ubicomp application development.
The expressiveness of the proposed design has
been tested by building a model of an Urban Traffic Control
application for Dublin city.
