Abstract
Contextual information such as spatial location can significantly
enhance the utility of mobile applications. We introduce the concept
of active preferences that represent a combination of user
preference information and choices combined with spatial or
temporal information. Active preferences set the policy on how a
mobile application should customise its behaviour not just for a
particular user but as that user moves to different locations and
interacts with other mobile users or with fixed location base
stations. We discuss technical issues for establishing a middleware
infrastructure to aid experimentation and describe our prototype testbed.
Keywords: middleware; location context; personal context.
